At present, more and more attention is paid to the sustainable development of enterprises. In particular, in the context of frequent financial crises and COVID‐19 pandemic, how the performance of listed companies' environmental, social, and governance (ESG) affects the company's market value has attracted widespread attention. Different from existing studies, this paper takes financial performance as a mediating variable and constructs linear regression model and mediating effect model based on analyzing the relationship between ESG performance, financial performance, and company market value and their influencing mechanism. The ESG rating data of Chinese listed companies newly developed by SynTao Green Finance from 2014 to 2019 were selected for empirical test. The results show that the improvement of ESG performance of listed companies can improve the market value of the company, and the financial performance of the company presents an obvious mediating effect. At the same time, operational capacity is an important mediating way for ESG performance to affect the company's market value. Further research shows that ESG performance of state‐owned listed companies exerts a stronger mediating effect on corporate operating capacity. Finally, this paper provides relevant suggestions for regulators, listed companies, and investors.

From the perspective of the policy impact effect, this paper takes green enterprises as the treatment group and polluters as the control group. Firstly, the double difference method (DID) was adopted to study the effect of green credit policy on enterprises from two aspects, namely the amount of loans obtained by enterprises and the financing cost. The study found that in terms of loan volume, the launch of “Green Credit Guidelines” enabled green enterprises to obtain more credit resources than polluters. In terms of financing cost, green credit policy means green enterprises obtain lower financing cost than polluters. The triple difference method is further used to test the impact of green Credit Guidelines on the access to credit resources and financing costs of enterprises. The results show that for enterprises with different property rights, the effect of green credit policy on non-state-owned enterprises is more significant than that of state-owned enterprises. For enterprises in different regions, the policy effect of green credit policy on enterprises in regions with relatively backward economic development levels is more significant than that of enterprises in regions with relatively developed economic development level. From the empirical results, the policy basically realized the original intention of directing credit resources to green enterprises and realized the Pareto improvement of financial resource allocation.

Inclusive finance is an important financial development strategy in the world. The promoting effect of the human capital on economic growth has also gained theoretical and empirical support. This paper attempts to deeply examine the interaction among inclusive finance, human capital and regional economic growth as well as their mutual influence mechanism. To the end, data of 31 provinces and cities from 2005 to 2015 were chosen to build a corresponding panel data template. Meanwhile, the fixed effect model was adopted for an empirical test. Results suggest the following. (1) Inclusive finance and human capital can exert a significantly positive promoting effect on regional economic growth. The influence of inclusive finance on regional economic growth is more obvious, while the nonlinear influence of human capital is more significant; (2) Inclusive finance is observed to have a significantly negative influence on economic growth of China’s central region (mainly referring to eight provinces, including Shanxi). The positive promoting effect of inclusive finance on economic growth of China’s west region (mainly referring to 12 provinces and cities, including Chongqing) is found to be the most significant. Differently, human capital exerts the most significantly promoting effect on China’s central region. The economic development level differs in different regions of China. As an increasing number of talent resources gather in the central and western region of China and the financial system is built in the two regions, resource optimization has become a necessity, which is the linchpin to China’s sustainable economic development.

Different from the existing literature which only studied the unilateral impact of the FDI or the ODI on economic growth, this paper took both the FDI and the ODI into the analysis framework of international capital flow on economic growth, and tried to introduce the mediating effect model to test the transmission mechanism and influence effect of international capital two-way flow on the economic growth. The results showed that both the FDI and the ODI can significantly improve the quality of economic growth, and the role of the FDI was stronger than that of the ODI. At the same time, the FDI and the ODI had obvious regional heterogeneity in promoting the quality of economic growth. International capital flow mainly requires three mediating effects to improve the quality of economic growth, which are the employment, the technology spillover as well as the output efficiency. The three effects of the FDI have a played significant role in promoting the quality of economic growth, while the ODI mainly plays a role through the improvement of output efficiency and technology reverse spillover. There are also significant regional differences in mediating effects.
