Taking the prevalence of the global green development concept and China's green credit development practice as the background, this paper constructs a theoretical model analysis framework with the incentive policy of green credit as the entry point. First, the impact effect of green credit incentive policy is examined using the BVAR model. The results show that the green credit incentive policy suppresses the output level in the short run through the financing constraint channel, but has a positive contribution to output in the long run due to the adjustment of the production structure and the dynamic adjustment of green investment and R&D. Next, the paper constructs a DSGE model embedded with green credit fiscal and tax incentive policies, which explains the impact mechanisms and comparative effects of fiscal and financial policies driving green credit. The model shows that the re-guarantee policy is the most effective and consensual green credit incentive policy. In terms of the policy combination, the combination of the re-guarantee policy and the income tax policy is the current optimal policy pairing, and its policy is able to produce an amplification effect through the balance sheet channels of commercial banks and enterprises at the same time. In addition, a certain intensity of the above policy combination not only can effectively increase the scale of green credit, but also does not produce significant negative shocks to output and inflation. In summary, the findings of this paper provide a useful reference for the formulation and implementation of green credit incentive policies.

In the process of green transformation of China's economy, it is of great practical significance to study the impact of green finance in supporting the development of the real economy, especially the impact of green credit on enterprise innovation, in order to promote the green transformation of enterprises, industrial structure upgrading and sustainable economic development. This paper takes green credit as a perspective and introduces it into the analytical framework of the impact of environmental regulation on corporate green innovation, through theoretical mechanism analysis and empirical testing, in order to reveal the impact and mechanism of green credit on corporate green innovation. It is found that green credit can effectively promote green innovation in heavy polluting enterprises, and it is mainly reflected in the increase of green utility model patent applications with a low degree of inventiveness. The promotion effect of green credit on green innovation is more obvious in regions with lower levels of economic development. Further mechanism analysis shows that green credit policy promotes green innovation of heavy polluting enterprises mainly through the incentive effect brought by changing financing environment and the pressure effect brought by increasing market competition. The findings of this paper can provide references for policy-making departments, banks and enterprises.

This paper investigates the impact of Chinese firms’ ESG performance on their financial constraint and financing activities. We find a negative association between firms’ ESG performance and their financial constraint driven by the Chinese government’s commitment to tackling climate change. Compared with state-owned enterprises (SOEs), non-SOEs have alleviated their financial constraint through both equity and debt issuance, thanks to the stock price appreciation and green credit. High-pollution firms benefit from both equity and debt issuance, while low-pollution firms mainly finance through equity issuance. Our findings demonstrate the leading role of the Chinese government in its domestic capital markets.

As the problem of global climate change becomes more severe, countries have proposed the goals of carbon capping and carbon neutrality. Green finance is an essential capacity support for achieving carbon peaking and carbon neutrality, and it can guide and stimulate social capital to invest in low-carbon industries and initiatives via marketbased mechanisms. Based on the panel data of Chinese prefecture-level cities from 2006 to 2020, this paper empirically examines the impact of green finance on carbon emission efficiency using a two-way fixed-effects model, conducts a regional heterogeneity analysis, and examines the threshold effect of economic development level and the mediating role of regional innovation. The results indicate that, first, green finance contributes significantly to the improvement of carbon emission efficiency, and second, the level of regional economic development has a double threshold effect on the contribution of green finance to the improvement of carbon emission efficiency. Third, regional innovation is an important green finance channel for influencing carbon emission efficacy. The sensitivity of carbon emission efficiency to the green finance index demonstrates an inverted U-shaped trend. Fifth, the importance of green finance sub-dimensions in relation to carbon emission efficacy is as follows: green support, green credit, green insurance, green investment, green equity, green bond, and green fund. These findings provide theoretical support for green finance's role in promoting co-carbon efficiency and are valuable for policy formulation.
