Research on the Impact of Technological Finance on Financial Stability: Based on the Perspective of High-Quality Economic Growth

(is paper investigates the relationship between technological finance, high-quality economic growth, and financial stability. Based on data of 30 provinces (including autonomous regions and municipalities) collected between 2004 and 2017, this paper adopts the method of factor analysis to construct comprehensive indexes of technological finance and financial stability before calculating green total factor productivity as the index of high-quality development, using the CRS Multiplicative Model. (en it constructs the spatial SACmodel and PVARmodel for analyses of the just-mentioned relationship based on the total sample of the nation and regional samples in eastern, middle, and western China, respectively. (e results reveal that (1) All samples, whether the total national samples or regional samples of eastern, middle, and western China demonstrate the positive influence of technological finance on high-quality economic development, with an obvious spatial spillover effect. (e impact factor is the highest in the eastern region, while the western region holds the lowest factor among the three. (2) Judging by the general national sample, technological finance has an obvious negative shock effect on financial stability within a short period, but the effect gradually dwindles as time goes by. (is rule applies to the sample of the eastern region, as its technological finance poses a shorttime negative shock effect on financial stability, before gradually diminishing to 0. Neither western nor middle regions have displayed an obvious shock impact on financial stability.


Introduction
e Chinese economy has progressed from the stage of highspeed growth to a high-quality one, and the importance of sustainable economic development cannot be overemphasized for the achievement of economic transformation.
e Fourteenth Five-Year Plan passed at the fifth plenary session of the 19th Communist Party of China (CPC) Central Committee proclaims "the promotion of high-quality development" as its keynote. It carries on existing policies that assert "the transformation of highspeed growth to high-quality development," demonstrating a new high level of Chinese comprehension and application of the law of economic and social development. e essence of high-quality economic growth is to increase the elementary investment-output ratio in the hope of achieving sustainable economic development with little factor input and environmental costs. Currently, the marginal utility motivated by resource factors in China is gradually decreasing.
rough the investment of immaterial factors, technological innovation can boost the transformation of development towards technological advance, knowledge accumulation, and labour qualities, solving the dilemma between the labor force and resource restraints while increasing factor productivity. Hence, technological innovation is the driving force behind high-quality economic growth.
Joseph Schumpeter is one of the earliest pioneers expounding on the relationship between financial support and technological innovation in his Economic Doctrine and Method (1911) [1]. He believed that the major motivation of economic development comes from innovation, the key issue of which is to fulfill new enterprises' credit demands. erefore, bankers play a key role in the choice of new enterprises and new technologies. Similarly, according to Hicks [2], a hundred years before James Watt's invention of the steam engine, scholars of physics were already acquainted with the knowledge of heat and pressure. e reason why the steam engine was invented in Britain and not any other countries is that Britain had a capital market of strong mobility. ese two scholars revealed that technological innovation alone is insufficient for stimulating economic growth. Another prerequisite for the application of new technologies is the existence of a mobile capital market. Other scholars have researched from perspectives like diversified financial market's risk dispersion of technological innovation [3], bank's guidance of technological innovation programs [4], and financial market efficiency's improvement of technological innovation capabilities [5].
To strengthen financial support of technological innovation, the Ministry of Science and Technology published Comments on Promoting the Union of Technology and Finance for Accelerating the Application of Independent Innovation Strategy in collaboration with the Ministry of Civil Affairs, Ministry of Public Security, Ministry of Foreign Affairs, National Railway Administration, Ministry of Transport, National Health Commission, General Administration of Customs, and Civil Aeronautics Administration. Later, it issued Pilot Implementation Agenda for Promoting the Fusion of Technology and Finance in collaboration with the Ministry of Finance, the People's Bank of China, China Banking and Insurance Regulatory Commission, and China Securities Regulatory Commission. Since then "Technological Finance" has become a popular concept. Based on scholars' views, here we interpret technological finance as finance's intervention of technological innovation, manifested as a series of financial policies, tools, and systems boosting the realization of technological achievements, encouraging and directing markets, enterprises, governments, and financial institutions to fund technological innovation activities, so that financial resources would accumulate within technological enterprises. In 2020, there were 145 companies listed in the Shanghai Stock Exchange Science and Technology Innovation Board, raising a total IPO of 222.622 billion Yuan, which is 1.7 times the amount of 2019. In early 2020, the loan balance of domestic technological enterprises reached 4.1 trillion Yuan, exceeding the figure in early 2018 by 38.9%. In 2020, 2.43931 trillion Yuan were invested in scientific research across the nation, which is 55.6% more than the amount in 2016. By the end of 2020, the effective amount of invention patents in China reached 2.213 million, which doubles the amount in 2016. e rapid development of scientific innovation effectively boosts the high-quality development of the economy. Compared with 2010, the high-tech products' export amount in 2020 has increased by 49% and reached 733.4 billion US dollars, while the technology market's business volume-2.8252 trillion Yuan-increased by six times. New service industries, including technology, information, and software service, keep growing rapidly, with the added value of strategic burgeoning industries taking up 15% of the GDP-a huge increase compared to the 4% in 2010. Meanwhile, in terms of industrial added value, the proportion of high-tech manufacturing among industrial enterprises above the designated size has increased from 9.4% (2012) to 15.1% (2020). In 2010, 52.1% of China's surface water bodies reached the level of Class III or beyond. A decade later, this figure has risen to 74.9%. In 2010, 2.185 million tons of sulfur dioxide were released as exhaust gas. In 2019, the figure dropped to 4.578 million tons, with an evident improvement in the environment. e contribution ratio of technological advances in China has risen from 43.2% (2005) to 60% (2020). China's comprehensive innovative capacity now ranks 15th in the world, as technological advance keeps boosting the nation's high-quality economic growth.
Yet the striking exclusivity of technological innovation is also worthy of our attention. Technological innovation is a long-term act involving huge investment and instability due to its immense complexity, high difficulty, and low success rate. It is wrought with risks coming from various aspects: technology, information, market, and financing. When participating in activities of technological finance, technological enterprises and financial institutions demonstrate striking information asymmetry. It is difficult for financial institutions to obtain an accurate evaluation of an enterprise's earnings persistence and credit risk in the future. Excessive nonperforming loans would lead to financial instability and economic turbulence. us, the development of technological finance has a "double-edged sword" impact on the real economy. On the one hand, technological finance enterprises can facilitate technological progress and industrial structure transformation and promote high-quality economic development; on the other hand, high-quality economic development does not mean financial stability. e characteristics of high risk and strong transmission of technological finance determine that increasing the scale of funds to technological finance enterprises will increase the accumulation of financial risks and affect financial stability. "Has technological finance reduced financial stability and aggravated financial systemic risks while promoting highquality economic development?" It has become an important proposition that needs to be tested. e report issued at the 19th National Congress of the Chinese Communist Party stresses the persistent strategy of technology-led development to accelerate the deep integration of technology and finance. Meanwhile, it also makes explicit the determination to fend against any systematic financial crisis. As technological finance takes up an even higher proportion in the financial business, some urgent issues need to be solved for the realization of healthy and sustainable development of technological finance: namely, how to achieve the coordinated linkage between technology and finance, how to curb the risks of the financial system while encouraging high-quality economic growth, and how to improve the fragile health of technological finance.

Definition of Technological Finance.
e word "Technological Finance" first appeared in an announcement issued by Shenzhen Science and Technology Bureau in 1993, entitled "Technology and Finance Jointly Support High-Tech Enterprises". (In Chinese, "technological finance" and "technology (and) finance" use the same four characters.) According to Zhao [6], technological finance is a systematic and innovative arrangement of a series of financial tools, institutions, policies, and services for the purpose of promoting science and technology development, achievement transformation, and high-tech industrial development. Herrera [7] pointed out that long-term loans from banks can encourage enterprises'interest in technological innovation. Based on samples collected in Taiwan, China, Tang and Chvi [8] concluded that risk investment can facilitate technological growth. Wang and Xu [9] believed that technological finance is a systematic arrangement conducted by agents of financial resources, like government, financial institutions, and market investors, to provide all sorts of capital and financial products, policies, and services to innovative agents devoted to innovative development, achievement transformation, and industrialization, including enterprises, universities, and research institutes. It aims at an organic union of the technological innovation chain and the financial capital chain. Ang [10] adopted Korean time series data and discovered the function of financial liberalization in technological innovation. Tadesse [11] found out that a marketoriented financial system benefits technological advances. According to Zhang et al. [12], technological finance is a series of financial tools promoting science and technology development, achievement transformation, and high-tech industrial development. ese tools include financial systems, policies, and services promoting industrial growth and governments, enterprises, market and social agencies funding science and technology innovation activities. In the meantime, technological finance is a key component of the financial system and national innovation system. Audretsch and Lehmann [13] concluded that venture capital tends to favor small and medium technological enterprises, and it evidently stimulates entrepreneurial development. Based on data of Italian enterprises, Benfratello [14] concluded that banking development encourages activities of science and technology innovation. Currently, scholars have not reached a consensus on the connotation of technological finance, though they do concur that the key of technological finance is its capital raising function in science and technology development. is paper interprets technological finance as policies and institutional arrangements conducted by various financial organizations and capital-such as governments and markets-to provide monetary support and financial services to activities of science and technology innovation.

Impact of Technological Finance on High-Quality Economic Growth.
Studies on the impact of technological finance on a high-quality economy have led to various conclusions. He [15] believed that some factors are restraining China's high-quality economic growth to a certain extent. ey include imperfection of relevant laws and regulations, insufficiency of shared service platform, monotonous fundraising pattern, inadequate industry innovation, and absence of professional talents. Deng [16] also pointed out that current technological finance falls short of ideal policies and regimes, hence its lack of persistent innovation and the restraint over high-quality economic development. Shao and Wang [17] believed that the system of technological finance is far from perfect, as its performance has been hindered by unavailable access to venture capital. Schwartz [18] analyzed the significance of finance and technological advances in the entire economic system. Finance boosts the development of technologies and lends support to the course of high-quality economic growth. e study of commercial banks, conducted by King and Levine [19], leads to the view that banks could make use of their information edge in programme selection for risk diversification. eir funding of technology enterprises effectively supports technological innovation and optimizes the quality of economic growth. Gu and Wang [20] investigated the spatial and temporal heterogeneity of the quality effects brought by Chinese technological finance's participation in economic growth. ey found out that the spatial and temporal trajectories of such quality effects are consistent with the changing level of technological finance's investment and the shifts of technology innovation capacity. Griffith et al. [21] believed that financial capital is mostly used by the enterprise for innovation and technology transfer. Using the total factor productivity as an index, they analyzed how technological progress increases the total factor productivity and subsequently stimulates high-quality economic growth. According to Zheng and Zhang [22], technological finance is of nonlinear relationship with regional technological innovation. Hsu et al. [23] classified samples into two categories: emerging economies and developed countries. eir discussion on the relationship between technological innovation and financial development leads to the discovery that the credit market and venture capital can encourage technological progress and high-quality economic growth. Zou and Ni [24] believed in the substitution effect of public technological finance. Beck et al. [25] used commercial banks' changing credit rates to evaluate the level of financial innovation.
eir study leads to the conclusion that the more drastically the credit rate changes, the higher level of technological innovation for technological enterprises. Besides, enhanced enterprise productivity stimulates high-quality economic growth. Chowdhury and Maung [26] believed that the impact of innovation investment on the high-tech industry is of positive correlation with the development level of the financial market. Xu et al. [27] gave a theoretical explanation of the notable promotion mechanism behind technological finance's impact on the high-tech industry's technological innovation. For Ilyina and Samaniego [28], finance is capable of effectively allocating resources to departments of advanced technology and high productivity. Once the issue of external funding for technological innovation is settled, technological development can be further enhanced for the realization of high-quality economic growth. In his analysis of Turkey samples, Adak [29] explained how investment in technological innovation can effectively improve productivity and hence the quality of economic growth.
ere are also some studies evaluating the efficiency of technological finance.

Technological Finance's Impacts on Financial Stability.
Technological finance benefits technological enterprises with financial capital inflow. Yet, due to the high-risk management of technological enterprises, such inflow also leads to financial instability and subsequent risks in the financial system. Technological finance is a financial resource targeting technological enterprises. Its risks come from both adjustments of financial structure and instability of the debtor. erefore, despite its promotion of high-quality economic growth, technological finance is fraught with financial uncertainties. Scholars have yet to reach a consensus on the role played by technological finance in financial stability.
e "facilitation school" holds that financial innovation is beneficial for risk transfer and diversification [30]. Zhang [31] pointed out that the growth of technological finance could stimulate the diversified development of financial institutions'businesses, improve fund allocation and operation efficiency of financial institutions. As a result, it could effectively optimize the financial market system, improve the market's capability to defend and deal with risks and crises, reduce the likelihood of systematic financial crisis and strengthen the stability of economic growth. Zhang and Gu [32] believed that technological finance achieves coordinated development with technological innovation systems via the technicalization of new industries, thereby achieving the goal of stabilizing the macroeconomy. Drasch et al. [33] believed that an in-depth fusion of finance and technology could encourage diversification of commercial banks' business and customers and reduce bad loan ratios and systematic risks.
On the contrary, the "destruction school" holds that the purpose of financial innovation is to transfer rather than diminish systematic risks, and it would lead to more financial turmoil in times of disorderly and excessive innovation [34]. Technological enterprise, due to its inherent instability, may increase the credit risks of financial institutions, whereas the mobility and conductivity of these risks would make financial systematic risks escalate. Duffey and Saull [35] believed that, due to the information asymmetry of the market as well as the high uncertainly of technological enterprises' sustainable profitability, financial institutions cannot obtain an accurate evaluation of asset quality via core technologies. is would lead to industrial default risks and economic turbulence. Geddes and Schmidt [36] pointed out the imbalance of functional structure in the development of technological finance. is issue could be manifested as the imperfect loan model of policy-based financial institutions, which is mainly direct loans that would worsen the risks of currency mobility within banks. Yang et al. [37] indicated that, while financial innovation in the banking industry helps to fulfill business demands raised by investors and customers, thereby realizing the self-interests of the banking institutions, such innovation would also lead to risk expansion of the entire banking industry. e analysis of Jiang [38] leads to the argument that, as financial innovation evades existing risks and encourages economic growth, it also amplifies the transmission effects of financial risks and may even result in systematic financial risks.
Existing literature has examined the impacts of technological finance on high-quality economic growth and financial stability, and their achievements are of great significance, though there is still room for improvement. (1) e indexes of technological finance, high-quality economic growth, and financial stability await further refinement, while there is some confusion concerning index variants. Judging from both domestic and overseas literature, scholars hold various understandings of "technological finance, which lead to distinct constructions of the technological finance index. Technological finance emerged in China only recently and there are insufficient statistics of relevant data held by financial institutions like banks. ese obstacles have troubled scholars working on technological finance. erefore, it is of immediate significance to choose comprehensive evaluation indexes that would truly reflect the Chinese condition. (2) Existing studies of technological finance mostly focus on the theories and efficacy measurement of technological finance. Technological finance and high-quality economic growth are normally regarded as two distinct subjects for study. Literature examining technological finance tends to focus on economic growth rather than the quality of such growth, though the latter is the key to China's economic transformation. (3) Academic studies on technological finance and economic growth have not stepped beyond the topic of their relationship. So far, few have paid attention to financial risks accompanying the development of technological finance or the impacts of technological finance on financial risks. Is it true that, along with its stimulation of high-quality economic growth, technological finance has also brought down financial stability and thus worsened financial systematic risks? (4) Most of the analyses on issues related to technological finance tend to be conducted within a certain region or across the nation. Due to the lack of regional comparison, existing research achievements have neglected the spatial features of economic variables. erefore, this paper extends the study to the following aspects: (1) e author makes further elaboration on technological finance, high-quality economic growth, and financial stability index, thereby constructing a comprehensive evaluation index system befitting the Chinese condition and of solid reliability. (2) is paper focuses on the quality of economic development, highlighting the goal of the age-high-quality economic growth. Empirical studies of technological finance and high-quality economic growth adopt the spatial econometric model, with regional spatial interaction taken into consideration.
(3) e current study incorporates the impacts of technological finance on financial stability, analyzing the shock effect brought by the former to the latter, thereby arriving at a more profound and objective examination of technological finance. (4) Based on existing research, this paper conducts both national and regional investigations on the relationship between technological finance, high-tech economic growth, and financial stability. e conclusions are generally applicable and attentive to specifics, serving as an empirical foundation for the making and application of differentiated policies.

Model Setup.
Given the research goal of the current paper, namely to analyse the impact of technological finance on high-quality economic growth and financial stability, here the core explanatory variable is technological finance, and the explained variables are highquality economic growth and financial stability. is section begins with the construction of an econometric model for the analysis of technological finance's impacts on high-quality economic growth. e research object covers thirty provinces (including autonomous regions and municipalities) since studies of regional economic issues could not neglect the spatial relativity of variables [39]. e method of spatial econometrics introduces the geographical location and reciprocal effects of a region into the model for the exploration of individuals' spatial changes and contributory factors within a region. us, this section establishes a spatial econometric model in the following form: (1) In formula (1), all variables are in vector form. e explained variable TFP is high-quality economic growth. TFI represents technological finance. M t is the set of controlled variables, and W, the matrix of spatial weights.
Existing literature tends to adopt 0-1 matrix as the setup for spatial weight matrix [40], which may lead to inaccurate results. is paper adopts economic distance to construct the weight matrix of each province (including autonomous region and municipality).

Core Variable
(1) Technological Finance. e selection of technological finance indicators mainly follows the scientific principle, which means that the indicators that can truly reflect the development level of regional technological finance should be selected. Based on the main sources of funds in technological finance: government, enterprises, financial institutions, and capital markets, public technological finance, technological finance market, and technological finance output are selected as measurement indicators. Based on the works of Zou and Ni [24] and Zhang and Gu [41], this paper constructs a comprehensive index of technological finance from three aspects: public technological finance, market technological finance, and technological finance output (see Table 1). e weight construction of this comprehensive index is based on the sum of three individual index weights, constructed in accordance with the respective indexes using factorial analysis.
(2) High-Quality Economic Growth. In the new normal, total factor productivity becomes the key driving force behind China's economic growth, bearing direct correlation with the dream to achieve more sustainable and much fairer development of higher quality and more efficiency. High-quality economic development is a more efficient and sustainable development. As the cost of labor and other factors in China continues to rise, and the constraints of resources and environment are becoming increasingly tight. e extensive development model of China that relied primarily on high input, high consumption, and high pollution in the past has become unsustainable. Highquality economic development is to achieve the maximum benefit with less resource consumption and lower pollution emissions, improve input-output efficiency, and cut down energy and environmental costs. Hence, this paper selects the green total factor productivity to measure the highquality economic development. is index is evaluated via the green total factor productivity. is paper adopts the method of the DEA-Malmquist-Luenberger Index for the assessment of green total factor productivity. is method has no restraint over the number of investment-output indexes. Construction of the output index could incorporate both desirable and undesirable outputs, along with resource and environment factors, to ensure an accurate evaluation of the high-quality economic growth index. After consulting the practice undertaken by Li et al. [42], this paper adopts the CRS Multiplicative Model of the reference set within a fixed period to measure the total factor productivity.
(3) Choice of Investment-Output Index. In this paper, investment covers three aspects, namely fixed asset investment, human capital investment, and energy investment. Calculation of the fixed asset investment is based on the work of Zhang et al. [43]. Here, we select the social fixed asset investment indicator and then calculate the capital stock of each province from 2004 to 2017 using the perpetual inventory system. e actual calculation runs as follows: K it � I it + (1 − δ)K it−1 K it is the capital stock of province i in the year t. I it is the amount of fixed asset investment of province i in the year t. δ is the depreciation rate, here set at 6% (Hall, 1999). 2004 is the base year, and the amount of its fixed asset inventory is calculated via K i0 � I i0 /(g + δ), after consulting Coe et al. [44]. K i0 Is the base year's capital asset, g is the economic growth rate of that year, and δ is the depreciation rate, calculated by running deflator on each province's fixed asset investment price index of that year. e index of human capital investment is calculated based on two indicators: the amount and the quality. e amount of human capital is the sum of each province's labour force working in the primary, secondary and tertiary industries. e quality of human capital is calculated according to the years of education one has received, i.e., S � S i L i / L i . In this formula, S is the maximum number of years receiving education for a given level, L is the number of people receiving each level of education. e maximum years of education for each level are, respectively, six years for primary school education, three years for both junior and senior high school education, and three years for higher education. e output index is Complexity 5 judged from two aspects-the desirable and the undesirable outputs-for a more accurate evaluation of high-quality economic growth. For the desirable output, the regional total output value is adopted-as the normal practice goes-and then deflated according to the GDP deflator indicator of the corresponding year. e undesirable output selects five indicators: wastewater, chemical oxygen demand, ammonia nitrogen discharge, sulfur dioxide emission, and total dust emission. e total power emission is the sum of industrial soot (dust) emission, life-related soot (dust) emission, and industrial dust emission (see Table 2).

Controlled Variables
(1) Level of Economic Development (AED). e level of regional economic development plays a key role in highquality economic growth, restraining a region's investment in improving technological innovation, humane environment, and natural environment. is paper adopts the regional GDP per capita as the proxy variable, which is deflated according to the GDP deflator index of each province.
(2) Scientific Research Investment (SRP). Endogenous growth theory maintains that scientific development motivates the development of economic society, and this paper treats the number of practitioners working in the respective fields of scientific research, technological service, and geological survey as proxy variables.
(3) Investment Rate (IRE). e ratio between the total amount of fixed asset investment and regional GDP is used as the proxy variable (see Table 3).

Data Source.
Provincial data adopted in this section comes from China Statistical Yearbook, China Statistical Yearbook on Environment, China Statistical Yearbook on Science and Technology, the National Bureau of Statistics website, and ESP database.
Due to the data deficiency of the Tibetan Autonomous Region, its data is removed and the research samples comprise data from 30 provinces (including autonomous regions and municipalities) between the years 2005 and 2017. e few missing data is replenished using interpolation and regression.

Spatial Autocorrelation Test.
Since this paper adopts the spatial econometric model for empirical study, we need to verify whether the data being examined is spatial dependent. is paper uses the widely adopted Moran's I Index to test the global spatial autocorrelation. e formula for this index is as follows: 2 /n is the sample variance, w ij is the spatial weight matrix, S 2 n i�1 n j�1 w ij is the sum of spatial weights. Results in Table 4 reveal that, between 2005 and 2017, the high-quality economic growth index, i.e., the Moran's I value, of 30 provinces (including autonomous regions and municipalities) have passed the significance test at 1%, 5%, and 10% levels, respectively. All the values are positive, indicating a significant spatial positive correlation among the high-quality economic growth indexes of each province (autonomous region and municipality).

Model Construction.
First, we use the LR and Ward tests, and the results are as follows: chi2(5) � 10.80, Prob > chi2 � 0.0555, chi2(5) � 24.48, Prob > chi2 � 0.0002. e original hypotheses θ � −βρ and θ � 0 are rejected, respectively. Neither SAR nor SEM models apply to the current study. en, we add the deviated lagging economic value and determine the applicability of SAC (SARAR) and SDM models according to AIC and BIC standards. e results demonstrate that the AIC figure has changed from 949.035 to 941.3444, and the BIC figure from 1022.871 to 987.9776. Both figures have become smaller, indicating that we should choose the spatial SAC (SARAR) model.
Results of the Hausman test are as follows: chi2(5) � 66.93，Prob > chi2 � 0.0000. erefore, we should use the fixed effects model rather than the random-effects model. Based on the results of the model applicability test, this paper adopts the two-way fixed effects model.

Estimated Results and Analysis.
is section begins with an estimation of the gross sample of 30 provinces (including autonomous regions and municipalities) in China. Since the developments of both the economy and the technological finance demonstrate obvious regional features, we divide the gross sample into three subgroups representing the eastern, middle, and western regions of China, according to the standards issued by the National Development and Reform Commission in 2003.
According to the results in Table 5, estimation of the national gross sample indicate that technological finance holds an evident positive impact over high-quality economic growth. Every time the figure representing technological finance rises by 1%, the one representing high-quality economic growth rises by 0.66413%. Estimation of the regional samples reveals that technological finance in all three regions also holds evident positive influence over the respective region's high-quality economic growth. e difference lies in the size of the impact factor. In the eastern region, technological finance proves to be a strong driving force stimulating high-quality economic growth, which increases by 1.39995% every time technological finance rises by 1%. In the middle region, high-quality economic growth rises by 0.66607% at every 1% increase of technological finance. e effect proves the be the weakest in the western region, as high-quality economic growth improves by a mere 0.17450% for the 1% rise in technological finance.
Judging from spatial interactions, both the national sample and the regional samples have demonstrated an evidently positive "spatial spillover"effect, indicating that the development of regional technological finance is positive encouragement to neighbouring regions' high-quality economic growth. is is due to the nature of technological finance as a union of technological innovation and financial assets, which can optimize resource allocation of neighbouring regions' human resources, technological resources, and capital, thus enhancing the production efficiency and economic growth there.

Robustness Test.
To test the robustness of technological finance on high-quality economic growth, this section runs estimation via constructing other controlled variables. ree variables are selected: infrastructure (ARE), human capital (HCL), and industrialization level (IDL). e infrastructure adopts the road area per capita as the proxy variable. e human capital level uses the ratio of the population receiving secondary and higher education to the entire population. As for the level of industrialization, it is the ratio between the second and the third industries' production. Judging by the estimated results of the robustness test listed in Table 6, the size and significance of individual variable factors differ,  Note: * , * * , and * * * represent, respectively, passing 10%, 5%, and 1% significance level test. e bracketed figure is the Z statistic value. whereas the core variable-spatial spillover factor of technological finance-remains the same. erefore, the results of technological finance and high-quality economic growth prove to be relatively robust.

Technological Finance's Impacts on Financial Stability
e union of technology and finance is an innovation. Within a short period, constructions of financial institutions, products (services), and systems started from scratch [45]. Such construction is accompanied by diversity and uncertainty, which, in other words, mean potential risks. And this section is a study on whether technological finance and financial stability can lead to shocks. e traditional VAR model fails to take regional heterogeneity into account. PVAR model considers both temporal and geographical factors and fetches information relevant to both, thereby establishing a more valid connection between the variables.

Model Setup.
In formula (3), all variables are in vector form. FSF represents financial stability; TFI, technological finance; i, the region; and t, the time. p stands for the model's lag order; β j , the regression factor of the lag endogenous variable; α i , the individual fixed effect; and ε it , the disturbance term. e PVAR model assumes that every cross-section shares an identical basic structure.

Complexity
(2) Financial Stability. Financial stability depends on both the macroscopic and the microscopic aspects [46]. Based on the work of Li [47], the financial stability index in this section is constructed as a comprehensive one joining three aspects: condition of macroeconomic growth, markets, and macrofinancial institutions, and markets and microfinancial institutions. e details are listed in Table 7. e weight is set in the same manner for the construction of the technological finance index mentioned earlier, i.e., using the factor analysis method.

Controlled Variable.
In this section, the controlled variable adopts the investment rate (IRE), using the ratio of fixed asset investment's total amount to the regional GDP as a proxy variable.

Data Processing and Data
Source. Data in this section comes from the wind database, China Statistical Yearbook, the National Bureau of Statistics website, and ESP database. Due to the data deficiency of the Tibetan Autonomous Region, its data is removed and the research samples comprise data from 30 provinces (including autonomous regions and municipalities) between the years 2005 and 2017, as we did earlier. e few missing data is replenished using interpolation and regression (see Table 8).

Stationarity Test of the Panel Data.
To avoid causing distorted results of the model estimation due to instationary data, this paper adopts the frequently adopted LLC and IPS for the panel unit root test. e results indicate that, after the first feasible region, all the data are stationary. e test results are listed in Table 9.

Choice of the Optimal Lag Order in the Panel VAR
Model. Assessment of this model requires us to choose the optimal lag order. According to T � 2P + 2, the maximum number for the lag order here is 5. Here are the results running for the optimal lag order according to the AIC, BIC, and HQIC rules.
According to Table 10, in the lag order test run within the range of 1 to 5, information volumes of AIC, BIC, and HQIC are the smallest when the lag order is 4. erefore, the optimal lag order in this model is set at 4.

Panel Generalized Method of Moment.
is section runs a panel generalized method of moment (GMM) on the estimation of the PVAR model. With reference to Love's procedure, we run the methods of cross-section mean difference and forward difference to eliminate the estimate deviation caused by temporal effect θ and α i . Results of the system GMM estimation in Table 11 demonstrate the negative impact of one lagging session of technological finance on the level of financial stability, which drops by an evident 1% with a factor value of −0.15290. If technological finance lags for two sessions, there is no significant impact on financial stability. A three-session lag would lead to a positive impact at the 5% significance level, with a factor of 0.03853. Four sessions' lag has not yet been found of any significant influence.
Judging by the pulse response function graphs of the national samples, technological finance is of a significant negative shock effect on financial stability, which reaches its maximum at the third session and then gradually drops low (see Figure 1).
Results of variance analysis in Table 12 reveal that only 4.505% of the financial stability's estimated variance comes from technological finance at the 10th session, whereas the results of the variance analysis at the 20th and 30th estimation sessions are relatively the same. It suggests that after the 20th estimation session, the impact of technological finance on financial stability has become mostly stable. Judging by the results of the 10th, 20th, and 30th estimation sessions, the estimated variance of financial stability comes mainly from itself and remains stable around 92%.
According to the method selected by the gross sample PVAR model's lag order, we run the similar procedure on PVAR models of the eastern, middle, and western region samples, and finally, confirm the GMM estimate results for the 3rd, 1st, and 5th sessions are (see Table 13): Figure 2 shows that, in the eastern, middle, and western regions, the response value of financial stability at its selfshock is positive within a short period, and then the shock gradually wanes. In the eastern region, technological finance's response to the shock of financial stability is negative within a short period, then the negative shock weakens and finishes at 0. In the middle and western regions, the shock on financial stability is barely visible. As for the impact of investment rate on financial stability, it is of little significance in the eastern and middle regions. In the western region, this impact holds positive for a short period and then weakens, demonstrating a trajectory that rises and falls and then rises again. is section replaces the investment rate index with the inflation rate since the latter proves to be of certain influence over financial stability [48]. Here we adopt the GDP deflator index as the proxy variable to examine the shock brought by technological finance on financial stability. e result does not differ much from what this thesis has presented, proving the robustness of our conclusion on the relationship between technological finance and financial stability.

Conclusion and Policy Implications
Based on the panel data of 30 Chinese provinces (including autonomous regions and municipalities) between 2005 and 2017. Based on the gross national sample and the regional samples, we have analyzed the relationship between technological finance, high-quality economic growth, and financial stability both theoretically and empirically. e results demonstrate that: (1) According to the gross national sample, technological finance holds an evident positive impact on high-quality economic growth. Every time the figure representing technological finance rises by 1%, the one representing high-quality economic growth rises by 0.66413%. e development of technological innovation is what motivates and evidently accelerates high-quality economic growth. Given its demand for sufficient funding, technological innovation can enhance its efficiency and level with increasing financial support, which would then be translated into the more effective promotion of high-quality economic growth. (2) Empirical study on regional samples demonstrates the positive influence of technological finance on high-quality economic development in all three areas, namely China's eastern, middle, and western parts. An evident spatial spillover effect can be observed. e difference lies in the size of the impact factor: the eastern region holds the largest impact while the western region is at the bottom. Technological finance tends to accumulate in regions of high-standard economic growth and abundant financial resources. e bigger the scale of the accumulation, the more advanced innovation capacity and economic effects would become. Once a cluster centering on technological finance is formed, technological, financial capital would start to accumulate and promote high-quality economic growth. e gathering effect of technological finance is also a spillover. Mobility of factors like financial capital, talents, and techniques exert positive effects on neighbouring regions' high-quality economic growth. e extent of such spatial spillover is closely related to the level of a regions' technological financial development.
(3) Analysis of the national sample demonstrates the significant negative shock effect of technological finance on financial stability within a short period. is negative shock then gradually weakens along with the passage of time. e biggest difference between technological finance and traditional modes of finance is that the former serves technological enterprises which runs high-risk business. e high risk and contagiousness of technological finance mean that funding technological enterprises would lead to the accumulation of financial risks, and eventually affect financial stability. As the financial system becomes perfected and the risk coping capacity improves, the negative impact of technological finance over financial stability also lessens, and the financial system gradually adapts itself to the development of technological finance. (4) In the eastern region, technological finance has an obvious negative shock effect on financial stability   within a short period, but the effect gradually dwindles as time goes by. Neither western nor middle regions have displayed an obvious shock impact on financial stability. Such regional difference suggests that financial stability is related to the level of regional development and the nature of trade. Enterprises in the middle and western regions are mostly of the traditional industry, with relatively little financial investment into the technological enterprises. erefore, the risk thus incurred would not affect the region's overall financial system much.
On the contrary, the eastern region is keen on technological innovation, with much financial investment on enterprises of technological innovation, hence the escalating financial risks.
As a financial resource devoted to the technological industry, technological finance is of great significance for China's entry into the new normal and transformation of the economic development model into high-quality economic growth. Technological finance is an ingenious child born out of the union between science and finance, yet its early stage of development is so unstable and risky that it brings a negative shock impact on financial stability. Based on the above findings, this paper proposes the following: (1) e government should display its vigorous financial support of technological innovation, increase fiscal investment in technological enterprises and encourage social capital's participation, to perfect the service platform for technological finance. Technological finance has innovatively enriched the scope of financial products and services, alongside its promotion of macroscopic high-quality economic growth. is innovative financial service optimizes resource allocation, achieve technological advance, and satisfy the needs of all sorts of technological enterprises. Innovation in financial tools and services has also widened the scope of financial options available for investors, bringing vibrancy to the capital market and unveiling microscopic effects of economic growth. In the meantime, we should shorten the regional gap of technological finance development. Governments of all levels should attach importance to the financial support of the technological industry and implement key policies-particularly in the middle and western regions-to stimulate financial institutions' transformation for the strengthened investment of technological finance in these regions. ese would help promote the development of technological industry in all regions. (2) We should strengthen the communication and interaction among regions. Enhanced regional connectivity can help neighboring provinces and cities to follow suit and make progress together, technological finance has a spatial spillover effect, and its development is of significance to the high-quality economic growth of all regions in China. We should establish a service platform of technological finance, combine regional resources for shared information so that technological finance could be communicated. We should also strengthen the support lent by technological finance to backward regions, transmit resources of technological finance to the neighboring region as a gesture of support so that technological finance would enjoy a mobile development in all regions and stimulate their high-quality economic growth. (3) We should strengthen the construction of the financial system to avoid financial risks. Innovative development of technological finance requires an institutional guarantee, hence the need for a fitting institutional framework. Government guidance and market operation should complement each other because the development of technological finance requires market promotion and the government supervises the procedure as the facilitator. Despite its stimulation of both technological and economic developments, the growth of technological finance, spurred by the inflation of financial capital, could also lead to a mismatch between financial resources and technological resources temporally and spatially. is would increase the overall risks of the financial system. (4) Policies concerning the development and regulation of technology should be designed in accordance with distinct regional features. Agents involved should be regulated under perfected laws and regulations on technological finance. All regions should monitor the status of technological finance development and mend its shortcomings in time for better coordination between technological finance and highquality economic growth. Affected by the regional levels of technological innovation and financial development, technological finance exerts heterogeneous influence over regional high-quality economic growth and financial stability. erefore, policies on developing and regulating technological finance should also be heterogeneously arranged.
