An Empirical Study on the High-Quality Development of “Specified, Refined, Characterized, and Innovative” Small- and Medium-Sized Enterprises under the Background of “Dual Circulation”: A Case Study of Wuxi City, Jiangsu Province

China attaches importance to the development of “specied, rened, characterized, innovative (SRCI)” smalland medium-sized enterprises (SMEs) under the background of the major strategic adjustment of the new pattern of “dual circulation.” is study studies the willingness and inuencing factors of SMEs through questionnaire survey, interview, and data mining of 147 technology-based SMEs, 20 “SRCI” small giant enterprises, and 146 NEEQ-listed enterprises by descriptive statistics and inference statistics. To promote “SRCI” quality development of SMEs, the policy suggestions are guided to consummate the related industry, the established companies’ cultivation library are improved, the public service platform of SMEs is established and improved, enterprises are guided to enhance independent innovation ability by “patent” to strengthen the innovative service supportability, and SMEs are guided to strengthen the echelon construction of talent team with the standard of high-quality development. Suggestions on strengthening the support for the listing of high-quality enterprises can provide a reference for the management of decision-making and enterprise practice of government departments.


Introduction
Small-and medium-sized enterprises (SMEs) are the basic force of scienti c and technological innovation. As the vanguard of China's science and technology, self-reliance "SRCI" SMEs have formed the key power source of highquality economic development, the key stabilizer of new development patterns, and the new force of the innovative country. With the background of the continuous strengthening of the country's cultivation of "SRCI" SMEs, especially the outbreak of COVID-19, and the major strategic adjustment of "double circulation," the emphasis on the development of "SRCI" SMEs has reached a new height in recent years.
President Xi attaches great importance to the development of SMEs and points out that "SMEs can do great things." e "14th Five-Year Plan for National Economic and Social Development and the Outline of Vision 2035" clearly stated that it is necessary to cultivate "SRCI" small giant enterprises, guide local governments to improve support policies and public service systems, and focus on supporting more than 1,000 enterprises in three batches. e high-quality development of a national-level "SRCI" small giant enterprise has driven about 10,000 SMEs to grow into national-level "SRCI" SME small giant enterprises. e "List of Practical ings to Do" for "SRCI" SMEs, which was recently issued, pointed out 10 speci c measures to carry out activities of 10,000 people to help 10,000 enterprises. Wuxi City, Jiangsu Province, has a clear goal, appropriate measures, and a strong guarantee for the cultivation project of "SRCI" enterprises and walks at the forefront of China. ere are 32 national-level "SRCI" small giant enterprises in Wuxi, ranked third in Jiangsu Province. e contribution of the "SRCI" enterprise group has become increasingly prominent.
e social influence has become increasingly extensive, and the development and growth of advantageous enterprises have provided important support for highquality development. "SRCI" has become a hot word. e high-quality development path and strategy of "SRCI" enterprises have become an important issue for us. How to build a high-quality development path and strategy for SEMs has become an important issue for us to face with the overall improvement of the reputation, competitiveness, and attention of enterprises and products.

Data Source.
e survey uses three batches of sample companies: (1) 146 companies listed on the New ird Board in Wuxi City; (2) 147 technology-based SMEs; and (3) 20 "SRCI" small giant enterprises. A total of 147 questionnaires were distributed, and a total of 147 questionnaires were recovered. e effective rate of the questionnaire was 100%.
is study mines the data of 313 enterprises in the sample cities and analyzes the overall characteristics and influencing factors of the willingness of SMEs in Wuxi to develop "SRCI." "SRCI willingness" is taken as the explained variable. "SRCI willingness" refers to whether SMEs intend to develop in the direction of "specified, refined, characterized, innovative." "SRCI willingness" is defined as a binary variable (Table 1), which is divided into two categories, one is to develop "SRCI" and the other is not to develop "SRCI." e categorical variables specifically are set as follows: "willing to develop SRCI" is 1 and "unwilling to develop SRCI" is 0.

Model Specification.
is chapter mainly conducts data analysis on the willingness of SMEs to develop "SRCI" through descriptive statistics and inferential statistics. Descriptive data are used to analyze the general characteristics of the willingness of SMEs to develop "SRCI" and descriptive analysis of the willingness of SMEs in Wuxi to develop "SRCI." A binary logistic regression model is usually used in inferential computing. e logit model is a probability unit model, which can analyze the probability that enterprises with different characteristics prefer to develop "SRCI" and analyze which characteristics that enterprises prefer to develop "SRCI" [1]. e specific formula is as follows: Due to the use of logit transformation in the model, the partial regression coefficients (i � 1, 2, . . ., n) of the respective variables represent the willingness of the interviewed companies to develop "SRCI" and the unwillingness to change each unit of the independent variable. e amount of change in the natural logarithm of the development "specialization and novelty" occurrence ratio exp(β i ) is the occurrence ratio, which means that the ratio of the probability that an enterprise is willing to develop "SRCI" and the probability of unwilling to develop "SRCI" is the multiple of the corresponding ratio before the change for each unit of change in the independent variable [2].

Empirical Analysis
In this study, the business situation, technology, and products, development strategy, R&D and innovation, development environment, problems, and suggestions are comprehensively investigated, as shown in Table 2.
From the perspective of industry classification, manufacturing (70.55%), software, and information technology services (10.27%) conform to the characteristics of 16 key industrial clusters of advanced manufacturing industries in Wuxi. From the perspective of enterprise scale, the proportion of large, medium, small, and micro-enterprises is 34.01%, 51.7%, 13.61%, and 0.68%, respectively. ere are 369,600 enterprises of various types registered in Wuxi City in 2020 and 58,600 newly registered enterprises of various types. It shows that the overall number of "SRCI" enterprises is not large, the proportion is small, and the cultivation volume cannot meet the urgent needs of enterprises to carry out "SRCI" development; the path mainly comes from "independent development" accounting for 89.8%. Independent development lacks coordination, and the level and efficiency of innovation are greatly reduced. From the perspective of technology and product promotion, the main part is exhibitions (91.84%), recommendation from old customers (68.71%), lack of deep participation in the Internet and big data applications, and e-commerce applications are mainly limited to online sales; publicity forms are single, especially if a single enterprise is unable to publicize and promote industrial cluster brands, local governments should actively undertake from the perspective of development environment, 83.67% of enterprises want the government to "formulate industrial guidance policies," 42.18% of enterprises want the government to "guarantee supporting factor resources," and 41.5% of enterprises want the government to "cultivate leading enterprises," 34.69% of enterprises want the government to "build a public service platform," and in all aspects of SME innovation and various stages of industrial development, enterprises hope to establish "province, city, county (district) linkage through the government" science and technology public service platform, open service.
ere are 10 explanatory variables in this study, and there will inevitably be correlations between explanatory variables. To improve the scientificity of the analysis results, it is necessary to use a multicollinearity test for each explanatory variable.
e method used in this study is the variance inflation factor (VIF) method. e results show that the maximum value of the VIF is 3.551, and all VIF values are less than 10, so there is no obvious collinearity between the explanatory variables, and there is no need to eliminate variables.
(1) In terms of "whether it is a high-tech enterprise," the willingness of high-tech enterprises to develop "SRCI" is significantly stronger than that of the control group, and the possibility is 1.232 times that of the control group. at is to say, high-tech enterprises are more willing to develop into "SRCI" enterprises with core competitiveness by improving their design innovation capabilities, strengthening product development, and accelerating technological upgrading [3].
(2) "Operating income" is also one of the factors that affect the development of "SRCI" enterprises. From the analysis results, it can be seen that enterprises with operating income between 50 million and 100 million yuan have lower operating income than enterprises with RMB 50 million, and their willingness to develop "SRCI" has been strengthened, but as the operating income further increases to 100 million to 1 billion yuan, this impact becomes negatively correlated, that is, after the operating income reaches a certain level. e willingness of enterprises to develop "SRCI" has declined. e reason for this phenomenon may be that after reaching a certain operating income, the enterprise will put more effort into production (or OEM) and develop "SRCI." e prospector input-output ratio of "SRCI" is not attractive to this part of the enterprise. (3) " e proportion of technical personnel in the total employees of the company" and "the proportion of R&D expenses in the operating income" are two important indicators to measure the innovation and R&D capabilities of enterprises. Enterprise R&D expenses and technical talents are the vitality of technological innovation. From the regression results, it can be seen that with the rise of these two indicators, the willingness of enterprises to develop "SRCI" has gradually increased. (4) "Financing demand" has no significant impact on whether an enterprise is willing to develop "SRCI." However, the Beijing Stock Exchange was officially established, and "SRCI" SMEs ushered in a historic growth opportunity.
According to the latest "Beijing Stock Exchange Listing Rules (Trial)" (Draft for Comments), as shown in Table 4, the research team conducted a statistical analysis on the financial indicators of whether the 146 New ird Board-listed companies in Wuxi meet the listing conditions, as shown in Figure 2. is study only considers "net profit," "operating income," "revenue growth rate," and "R&D investment." Among the 146 companies in this survey, 17 are in the innovation layer and 129 are in the basic layer. Among the 17 innovation-level enterprises, 7, 14, and 13 meet the criteria of "net profit," "income," and "income + R&D investment," respectively, and 17 meet one of the three criteria. at is, all 17 innovation-level companies meet the financial standards for listing on the Beijing Stock Exchange. Among the 129 basic-level enterprises, 12, 73, and 98 meet the criteria of "net profit," "income," and "income + R&D investment," respectively, and 115 meet one of the three criteria. Seizing the opportunity, listing on the Beijing Stock Exchange has set an example for the city's SMEs to expand financing channels, Evaluation of "SRCI" policy "SRCI" willingness marking that Wuxi City has entered a new stage in the process of promoting the capital market to serve SMEs.
(5) e "number of patents" has no significant impact on whether an enterprise is willing to develop "SRCI." is is mainly because the development of "SRCI" enterprises only needs to obtain 2 invention patents or software copyrights related to the main products. Under the influence of the driving strategy, intellectual property rights such as patents have been integrated into the texture of high-quality development of enterprises. However, the "number of trademarks" and the "number of qualification certificates" have a significant impact on whether enterprises are willing to develop "SRCI." At the same time, this study excavated the data of 146 NEEQlisted enterprises in Wuxi City in the past four years and constructed the "New Patent_Revenue" indicator, that is, the total number of newly applied valid invention patents divided by the latest operating income data. e larger the value of this indicator, the more authorized patents it has obtained under the condition of similar operating income, thus indicating that the company has strong innovation ability. e research team separately counted the average of "SRCI" enterprises and "non-SRCI" companies and calculated the ratio. If the ratio result is greater than 1, it can indicate that the average value of the "New Patent_Revenue" indicator of the "SRCI" enterprise is greater than the average value of this indicator of other companies. e statistical results are shown in Figure 3. (6) Compared with enterprises that do not understand the policy of "SRCI" (1-3 points), the willingness to develop "SRCI" is not significantly enhanced for enterprises that have some understanding of the policy (4-7 points). However, when the company has a very good understanding of the policy (8-10 points), the probability of the company's development of "SRCI" is significantly increased, which is 1.356 times that of the reference group. Similarly, when the company has a very high evaluation of the policy implementation effect (8-10 points), its probability of developing "SRCI" is 37% higher than that of the control group (1-3 points).

Suggestions
In this research, we believe that if we can promote the government, scientific research institutes, universities, industry associations, entrepreneurs, etc., to take joint actions through appropriate institutional arrangements, paths, and strategies to help SMEs achieve high-quality development of "SRCI." It can realize the upgrading of Wuxi's industrial clusters and can promote the transformation of Wuxi's entire regional economy. 1. e average operating income in the past two years is ≥100 million; 2. the total R&D investment in the past two years accounts for ≥8% of the total operating income in the past two years

Continue to Expand Corporate Financing Channels and Need to Increase Support for High-Quality Companies to Go
Public. Wuxi City has thoroughly implemented the industry-leading strategy and the innovation-driven core strategy and supported the listing of enterprises and listed companies. e listing work has become an important focus of the city's development of the real economy. With the official establishment of the Beijing Stock Exchange, "SRCI" SMEs ushered in a historic growth opportunity, which further stimulated the development vitality of "SRCI" SMEs. First, various public service platforms for SMEs, etc., are fully used, the development of investment and financing docking and project roadshows for SMEs is promoted, corresponding government investment funds, venture capital (VC), and private equity funds (PE) are regularly organized, and equity financing and non-public issuance [10] are conducted. e second is to summarize the successful cases of listed companies, promote the good experience and good practices of high-quality listed companies and listed companies using the capital market to achieve high-quality development, and give full play to the role of high-quality listed companies as "facilitators" [11].
e third is to strengthen policy publicity, classification, and cultivation and special counseling, for the listed companies that meet the listing requirements of the Beijing Stock Exchange, and they should give all the support and start the listing work as soon as possible [12]. e fourth is to establish a joint meeting system for listing work, a reserve company database for listing, implement precise support, and build an echelon of companies listing. e pattern is nurtured.
Starting from the basic situation of the enterprise, the operation of the enterprise, technology and products, development strategy, R&D and innovation, development environment, and other factors, this study analyzes in detail the factors that affect the willingness of SMEs to develop "SRCI" in the sample locations. e relevant research on the development of "SRCI" for small SMEs still needs to be further developed and deepened. First of all, there are many factors influencing the willingness of SMEs to develop "SRCI." Although this study analyzes the influence of various factors on the willingness to develop "SRCI," there are still many factors that need to be analyzed, such as brand strategy and differences in the development level of enterprises and industries; secondly, the financial support system and its related institutional arrangements directly affect the willingness of SMEs to develop "SRCI," while the relevant policies of different cities are difficult to quantify. It is also difficult to estimate the impact of the "SRCI" willingness. erefore, the continuous follow-up investigation and research on the "SRCI" of the development of SMEs need to be further carried out.
