Introduction
e construction and sustainable development of the Guangdong-Hong Kong-Macao Bay Area are an important strategic decision at the national level. In February, 2019, the CPC Central Committee and the State Council issued the outline of the development plan for the Guangdong Hong Kong Macao Bay Area, which clearly pointed out that the Guangdong-Hong Kong-Macao Bay Area should be built into a vibrant world-class urban agglomeration, an international science and technology innovation center, an important support for the construction of the "the Belt and Road," and a demonstration area for in-depth cooperation between the mainland and Hong Kong and Macao; and a high-quality life circle suitable for living, working, and traveling should be created to become a model of highquality sustainable development.
e new strategic positioning requires the greater Bay Area cities to be equipped with a good regional business environment to provide allround and deep support for high-quality business, from trade circulation to high-tech from cultural creativity to service industry. A good regional business environment is conducive to the rapid and high-quality growth of enterprises and can effectively enhance the core competitiveness of the city. It is an important embodiment and foundation of the economic strength of Guangdong-Hong Kong-Macao Great Bay area. However, the business environment of cities in the Guangdong-Hong Kong-Macao Greater Bay Area is quite different. Important node cities play different roles in the development of the Greater Bay Area, and important node cities play different roles in the development of the Greater Bay area. For example, Hong Kong needs to consolidate and enhance its status as an international financial, shipping, trade center, and international aviation hub. It should promote high-end and high-growth development in finance, commerce, logistics, and professional services and build itself into a more competitive international metropolis. Guangzhou should give full play to the leading role of a national central city and a comprehensive gateway city, comprehensively enhance its functions as an international business center and a comprehensive transportation hub, cultivate and enhance its functions as a scientific, educational, and cultural center, and strive to build itself into an international metropolis. Shenzhen should give full play to the leading role of the special economic zone, the national economic center city, and the national innovation city, accelerate the construction of a modern and international city, and strive to become a city of innovation and creativity with world influence. In order to fully stimulate the economic vitality of the Guangdong-Hong Kong-Macao Greater Bay Area and continuously optimize the regional economy, it is particularly important to explore the influencing factors of the regional business environment of important node cities.

Literature Review
"Business environment" was first proposed by the "doing business" project of the International Finance Corporation of the world bank group. It refers to the sum of all kinds of surroundings and conditions accompanying the whole process of enterprise activities. It is a systematic project for designing economic and social reform and opening to the outside world in many fields. Since the World Bank first released the Doing Business Report in 2003, it has taken 17 years to objectively measure the business environment of 190 economies, providing objective basis, comparison, and reference for each economy to create a good business environment. However, due to the differences in the political and economic systems of countries around the world, the World Bank's measurement indicators cannot effectively match the actual situation of countries and regions [1]. In recent years, under the initiative of the central government to improve the "rule of law, internationalization, and facilitation" business environment, local governments at all levels in China have actively explored ways to optimize the business environment in line with local development realities. First, the World Bank business is used as a template to intercept some evaluation indicators in line with the current situation of local economic development. Second, with the help of the intellectual support of institutions of higher learning, scientific research institutions and other units carry out in-depth cooperation for comprehensive evaluation. erefore, many domestic scholars have put forward different research directions on the influencing factors of business environment. Yang [2] used factor analysis to measure the business environment of Shandong, Jiangsu, Zhejiang, and Guangdong provinces from three first-level perspective of market environment, policy and government environment, and legal environment. Wu and Zhang [3] constructed 10 first-level indicators, including overall evaluation, government efficiency, administrative approval, market supervision, legal environment, credit environment, financial environment (financing environment), human resources environment, social environment, and infrastructure environment from the three dimensions of overall perception, government environment perception, and factor environment perception. Peng and Ma [4] selected four firstclass indicators, that is, demand identification, service capability, service function, and service supply as evaluation dimensions. Yan [5] built a business environment satisfaction evaluation model based on five first-class indicators, including government policies, talent protection, market supervision, legal environment, and financial support. Peng et al. [6] selected 23 indicators from the four aspects of economic environment, market environment, basic environment, and supporting environment to build an evaluation index system for regional business environment.
Many scholars have done the research on business environment and satisfaction evaluation, but the application of evaluation system in Guangdong-Hong Kong-Macao Greater Bay Area is pretty new and meaningful. Based on the research results of the world bank and domestic and foreign scholars on the business environment, this paper focuses on five soft environment aspects: policy support, talent security, market supervision, financial support, and cultural promotion. e policy support includes the compliance of policy objectives, the degree of government information disclosure, and the government's response to demands. Talent security includes talent cultivation, supporting services and apartment housing. Market regulation includes regulation of code of conduct, reasonable frequency of regulation, and attention to fairness of conduct. Financial support includes the financial base, the number of financial institutions, and the fit of financial services. Cultural promotion includes the atmosphere of innovation and vitality, the level of opening to the outside world, cultural industries, or cultural brands.

Basic Information about Sample Data.
e outline of the Guangdong-Hong Kong-Macao Great Bay Area Planning clearly points out that it is necessary to "give play to the leading role of the strong alliance between Hong Kong and Shenzhen, Guangzhou and Foshan, and Macao and Zhuhai" and give Hong Kong and Shenzhen, Guangzhou and Foshan, and Macao and Zhuhai very high political standards. However, in reality, the weight of this pole is obviously insufficient, and the degree of economic connectivity and integration is far less than the other two poles. In order to solve this objective contradiction in theory, based on the research foundation of the 2020 Guangdong Province innovation and strengthening school project (Research on the path of Zhuhai Macao coordinated optimization of business environment), this paper analyzes the influencing factors based on the statistical data of the regional business environment of Australia Zhuhai one pole. e specific results are shown in Table 1.
It can be seen from Table 1 that the data source comes from the middle-level and above employees of enterprises registered in Zhuhai or Macao. e degree of business integration between the two cities is low, and only 22.6% of enterprises have business intersection. e proportion of private enterprises and small-and medium-sized enterprises is large, indicating that the two cities have strong market activity. As a transportation hub city, the proportion of Commerce and trade circulation industry (such as wholesale, retail, transportation, warehousing, leasing, and business services) is relatively high, up to 28.2%. In addition, the scale of new enterprises in the two cities is not very prominent, there are few mature enterprises, and growth enterprises account for a large proportion.

Sample Data Reliability and Validity
Tests. Due to the research on the source of statistical data, reliability and validity tests were carried out on the sample data in order to objectively test the sample data to truly reflect the degree of variables and ensure that scientifically refined measurement dimensions further fit the reality and maintain the stability of the test. e results are shown in Table 2, in which the KMO values are greater than 0.7, and the significance level of Bartlett sphere test is less than 0.05, which meets the validation criteria and has good validity. e commonly used alpha reliability coefficient method is adopted in the study, and each reliability value is greater than 0.8, which shows that the scale has high reliability and can meet the research requirements.

Research Methods.
e logical analysis of the objective data of the regional business environment assessment system has been highly respected, but the research based on the perception of market players is not good. Under the socialist market economic system, the market is the distributor of social resources. Considering the regional business environment, enterprise satisfaction should be an important part of the evaluation system. In order to measure the perception of market participants, this paper uses the customer satisfaction studied by American scholar Cardozo for reference and introduces enterprise satisfaction as the dependent variable, which is defined as the measurement of the gap between the actual feeling and expectation of market participants on the regional business environment. And this paper considers whether the regional business environment will continue to improve. In this paper, one-way ANOVA and Cobb Douglas function are used as research methods.
3.3.1. One-Way Analysis of Variance. When other factors are fixed and unchanged, the one-way variance only considers whether there is a significant difference in the mean value of dependent variables at different levels of a single factor and set in the test of the equality of K overall mean values: H 0 : μ 1 � μ 2 � · · · � μ k H α : the means of k populations are not all equal. e rejection rule is P-valued method: if so P-≤α, reject H 0 .
Using one-way ANOVA, we aim to explore the ratio of the systematic deviation of a control factor to six measurement dimensions and the randomness deviation that cannot be explained by this factor and then derive the characteristics of whether there is a significant difference.

Cobb-Douglas Function.
In order to objectively calculate the degree of influence of five measurement dimensions on the regional business environment, this paper constructs a regional business environment influencing factor model based on the transformation of the Cobb-Douglas function of the new economic growth theory. For the convenience of research, it is referred to as business environment (DB), policy support (PS), talent security (TG), market supervision (MS), financial support (FS), and cultural promotion (CS). DB = µPS α TG β MS ε FS θ CS λ . To eliminate the effects of heteroscedasticity, a logarithm can be obtained on both sides of the above equation: (1) Among them, µ is the on-standardized coefficients α, β, ε, θ, λ are the flexibility coefficients of policy support, talent security, market supervision, financial support, and cultural promotion. Table 3, in addition to cultural promotion, individual positions have significant differences in evaluation for the remaining five dimensions. Among them, the legal representative has the highest evaluation in several dimensions, followed by senior managers and the lowest middle managers. e legal representative and the senior managers have a more macro environment, and the difference between the two is also small. e middle managers have a weaker feeling about the 5 dimensions due to the limitations of the position. e strong commonality of cultural promotion has resulted in no significant differences found in different functions. e registered enterprises in the two cities have significant differences in the five evaluation dimensions, among which the perception of policy support and talent protection of registered enterprises in Zhuhai is higher, while the perception of registered enterprises in Macao in terms of market supervision, cultural promotion, and financial support is higher. Regarding balanced comprehensive factors, there is no significant difference in the Discrete Dynamics in Nature and Society Discrete Dynamics in Nature and Society perception of the business environment of registered enterprises in the two cities, which shows that there is complementarity between the influencing factors of the business environment, and each has different urban advantages. ere are significant differences in the business environment of business intersection concentration, and the specific performance of policy support and market supervision is the biggest difference between the business environment of Zhuhai and Macao. Enterprises with business dealings can feel different policy environments and market environments, and their average evaluation is significantly higher than that of a single city.

4.2.
One-Way ANOVA of Industry Types. Table 4 shows that the degree of difference in the business environment of different types of enterprises is very prominent. Among the policy support, transportation, retail, leasing and business, and other commercial circulation industries have higher average evaluation values. e two governments allowed them to give full play to their location and geographical advantages and carry out many effective measures to promote the development of circulation formats. In addition, high-tech industries such as software and information technology service industries in Zhuhai and Macao are embracing new development opportunities. At the same time, the industrial structure of the two cities has shifted to the tertiary industry, the proportion of the primary industry is extremely low, and the average evaluation of the primary and secondary industries ranks last. In the talent guarantee, the government has given greater efforts to emerging industries such as software and information technology service industries, and emerging industries has achieved good results. In contrast, industries such as industry, agriculture, and postal and express delivery industry are difficult to attract higher-level talents due to the low entry threshold, and the talent guarantee is at a relatively backward level. In market supervision, in addition to high-tech and other key industries, in the catering and accommodation industry, because it involves the vital interests of the people, the regulatory behavior and frequency are more scientific and reasonable, and the average evaluation is higher. Among the financial support, leasing and business services have a relatively close relationship with finance, and the average evaluation value is higher. Due to the relatively weak financial foundation of Zhuhai and Macao, the evaluation of other industries is not prominent. In the promotion of culture, the two cities are both tourist cities, and catering, accommodation, and other exportoriented economy attract the strongest feelings of foreign floating populations, reaching more than 11.1, and software and information technology service industry and other key industries are also the focus of culture attraction of the two cities. In general, the average business environment evaluation of the catering and accommodation industry, which is mainly affected by tourists, and the key supported commercial circulation and high-tech industries is significantly different from that of other industries, and the average price of the primary and secondary industries is the lowest.

One-Factor ANOVA Analysis of the Nature of the Enterprise, Size of the Enterprise, and Length of Enterprise
Registration. In the nature of enterprises, except for talent security and financial support, the other evaluation dimensions are significantly different (see Table 5). e developed private economy of the two cities is mainly expressed in the form of limited liability companies and individual private enterprises, and the policy inclination is relatively large. e investment enterprises in Hong Kong, Macao, and Taiwan are emerging in an endless stream, and the governments of the two places have paid close attention to them. Comparatively speaking, the two cities pay more attention to competition guarantees and give the private economy and other different types of enterprises an "open, just, and fair" market environment. e average market supervision evaluation of the private economy and other different types of enterprises is higher. In the promotion of Discrete Dynamics in Nature and Society culture, the private economy and other different types of enterprises are more in line with market demand, more likely to be affected by cultural appeal, and the average evaluation is higher. Overall, the business environment of the two cities is more friendly to the private economy and has a higher evaluation. At the same time, the proportion of the state-owned economy and the collective economy is low, and the perception and evaluation of policies, markets, and cultures are at a low level. From the scale of enterprises in Table 5, it can be seen that, in addition to financial support and cultural promotion, there are significant differences in policy support, talent protection, market supervision, and business environment. e average policy evaluation of small and micro enterprises is high, which is in line with the policy orientation of the two cities. e number of large enterprises is small, and the government also pays special attention. In recent years, the two cities of Zhuhai and Macao have vigorously introduced foreign populations and do a good job in supporting talents. e cultivation of talents and housing guarantee of large enterprises have been effectively alleviated. e talent requirements of small and micro enterprises are not high, which coincides with the demographic characteristics of strong mobility. At a result, the average talent evaluation of large and small and micro enterprises is higher than that of medium-sized enterprises. In market supervision, small and micro enterprises are mostly emerging industries. e market environment in Zhuhai and Macao is more tolerant, and the average evaluation of small and micro enterprises is also higher than that of large and medium-sized enterprises. In general, the business environment of Zhuhai and Macao cities pays more attention to small and micro enterprises, and the average evaluation value is higher. Due to industrial supporting facilities and industrial cluster effects, the perception and evaluation of large and medium-sized enterprises need to be improved. In the duration of registration, there were no significant differences in other evaluation factors except for cultural promotion and business environment. Factors such as cultural atmosphere, openness level, and cultural industry support require time to experience. e longer the enterprise exists, the stronger the perception of culture will be, and the higher the average evaluation of cultural role will be.

Analysis and Discussion on Different Influencing Factors on Regional Business Environment
As can be seen from the above, there is a significant influence relationship between the five influencing factors and the business environment, showing different role status between different categories. However, how correlated are any two influencing factors? It is a problem that must be faced squarely to explore the internal logical relationship between influencing factors. Further, it is necessary to explore the common role between the five influencing factors and the business environment, and to find out the role of different factors on the business environment. Based on this, the following is an analysis of the interaction between individual factors and the interaction of combined factors. Table 6 analyzes the correlation of the overall data of Zhuhai and Macao, and it can be obtained that (1) there is a significant positive correlation between the six evaluation dimensions, of which the Discrete Dynamics in Nature and Society optimization effect of building a soft environment and enhancing cultural strength on the business environment is becoming prominent. e business environment is affected by market supervision, policy support, and cultural promotion, and the correlation coefficient is above 0.6. e policies of Zhuhai and Macao are highly transparent, highly in line with market demand. Market supervision is relatively strong and pays attention to norms, and the cultural commonality of "openness and inclusiveness" plays a role in the penetration and aggregation of soft power, which is significantly improving the level of business environment.

Degree of Individual Action.
(2) Due to the current situation of financial foundation and the current situation of talents, it is difficult to give full play to the effectiveness of policies in the short term. e correlation coefficient between policy support and financial support and talent security is about 0.3, and the financial foundation of the two cities is relatively weak. e economic volume cannot support a more developed financial scale, and the policy dividend is difficult to see immediately in the short term. At the same time, the population size of the two cities has long been at the end of the Guangdong-Hong Kong-Macao Greater Bay Area urban agglomeration, the talent base is inherently insufficient, the attractiveness and advantages of talents are not obvious, and the high housing prices in the two cities are also an important loss of talent security.
Further, Table 7 compares the correlation between the variables of the two cities, and the following can be obtained: (1) there is a significant positive correlation between the six evaluation dimensions of the two cities of Zhuhai and Macao. e data show that the correlation degree of most of the evaluation dimensions is not much different. (2) In addition to market supervision, Zhuhai's degree of correlation between policy support and other dimensions is higher than that of Macao, especially the degree of correlation between policy support and talent protection, which shows that the Zhuhai government's policy effect in talent protection is stronger, and the implementation of the "Talent Plan" effectively attracts, trains, and serves all kinds of high-level and high-skilled talents. Macao's long-term talent supply is insufficient, and talent protection lacks a spatial foundation. (3) In addition to policy support, Macao's degree of correlation between market supervision and other dimensions is higher than that of Zhuhai, which reflects that Macao's industrial supervision, corporate credit, safety production, and other regulatory behaviors are more standardized, and more attention is paid to the frequency and level of supervision. Zhuhai's market supervision is dominated by traditional means, and the supervision method of "strong government and weak society" limits the level of supervision to a certain extent. Discrete Dynamics in Nature and Society   Discrete Dynamics in Nature and Society From the above three Cobb-Douglas functions, it can be compared that (1) the financial support has not been combined with other factors to affect the business environment in Zhuhai.
is further reflects the uneven and insufficient situation of Zhuhai's overall financial industry, and the problem of incongruity with the development of the real economy is more prominent. When the other four factors jointly act on Zhuhai's business environment, the flexibility coefficient of policy support is the highest, and the rest are cultural promotion, market supervision, and talent protection. (2) e failure of talent security to have a joint effect with other factors affecting Macao's business environment is related to Macao's talent dilemma, the shortage of population supply, and the single skill structure, and the introduction of mainland talents has been in a "contradictory" situation for a long time. When the other four factors are combined to act on Macao's business environment, the elasticity coefficient of market supervision is the highest, and the rest are cultural promotion, policy support, and financial support. (3) When the five factors jointly act on the business environment of Zhuhai and Macao, they can produce significant correlations, and the elasticity coefficient of Chinese promotion is the highest, and the rest are policy support, market supervision, talent security, and financial support.

Conclusions and Recommendations
In order to explore the influencing factors of the regional business environment, this paper focuses on the five aspects of policy support, talent security, market supervision, financial support, and cultural promotion, and it takes Zhuhai and Macao registered enterprises for empirical analysis.
e following conclusions are drawn: first, five factors in different categories have different degrees of significant impact on the regional business environment, among which the industry type has the greatest impact (both significant). In addition to cultural promotion, personal position also has a significant impact. e registered city of enterprises does not significantly affect the business environment, but it has the complementary effect of influencing factors overall. e significant impact of business exchanges between Zhuhai and Macao on the business environment is reflected in the policy support and market supervision. e nature and scale of the enterprise are not significantly affected by some factors. Apart from cultural promotion, the duration of registration does not significantly affect the business environment. Second, there is a significant positive correlation between the six evaluation dimensions of Zhuhai and Macao. ere is no significant difference in the correlation degree of most evaluation dimensions. However, the correlation degree of policy support and other dimensions in Zhuhai is higher than that of Macao, and the correlation degree of market regulation and other dimensions in Macao is higher than that of Zhuhai. In the joint effect, financial support failed to have a joint effect with other factors to affect the business environment in Zhuhai, and talent security failed to combine with other factors to affect the business environment in Macao.
irdly, the five factors have a significant impact on the regional circulation business environment of Zhuhai and Macao, among which the biggest impact of Zhuhai is policy support (the largest elasticity coefficient), the smallest impact is financial support (no significant correlation), the largest impact of Macao is market supervision (the largest elasticity coefficient), and the smallest impact is talent security (no significant correlation). e integration of Zhuhai and Macao can produce a significant correlation. e greatest impact is cultural promotion (the largest elasticity coefficient), and the smallest impact is financial support (the smallest elasticity coefficient).
Based on this, this paper puts forward the following suggestions: (1) according to the industrial characteristics Discrete Dynamics in Nature and Society and enterprise types of the important node cities in Guangdong, Hong Kong, and Macao, this paper proposes political measures for different factors affecting the region's business environment, especially paying attention to the specific needs of different industry types, and comprehensively optimizes the regional business environment from the perspectives of policy, talent, market, finance, and culture to ensure the sustainable and high-quality development of the Greater Bay Area. (2) Objectively evaluate and introduce the element resource differences of important node cities in Guangdong-Hong-Kong and Macao Great Bay Area, build a fusion platform for regional business environment through multiparty cooperation, launch a "one-to-one," "one to many," or even "many to many" communication and coordination mechanism, and implement a new path of binding development of regional economy. (3) Seek the complementary effect of resources between the important node cities in Guangdong-Hong-Kong and Macao Great Bay Area, build a multiagent policy cooperation operation mechanism, enrich the new connotation of talent attraction and cultivation among cities, promote the construction of joint guarantee market mechanism, carry out a new model of multinode financial coordinated development, and work together to enhance the cultural soft power of the important node cities in Guangdong-Hong Kong-Macao Bay area, so as to achieve the sustainable and high-quality development of Guangdong-Hong Kong-Macao Bay area. e research was made based on two cities, Zhuhai and Macao, and we hope to have more data on more cities in Guangdong-Hong Kong-Macao Bay area to make the analysis more accurate and adaptable [7][8][9][10][11].
