Through the use of 30 provincial panel datasets covering the years from 2013 to 2017, on the basis of constructing the regional green development indicator system, this paper used the fixed-base range entropy weight method to measure the regional green development level. The difference-in-differences model was used to test the policy effect, the mechanism of the establishment of the green financial reform, and the innovation pilot zone on green development. The results showed that: (1) the establishment of the pilot zone promotes regional green development and shows regional differences; (2) under the guidance of policies, the provinces that set up the pilot zone affect the level of regional green development mainly through the upgrading of industrial structure and technological innovation; further research has found (3) a high level of financial investment in environmental protection and marketization, which will help the pilot zone to further play a positive role in promoting the green development of the region. The results of this article indicated that China should continue to expand the scope of green finance reform and innovation pilot zones and make reasonable arrangements among regions according to local conditions to explore new ways of promoting green development. At the same time, the government should actively play the role of green finance in the pilot zone to promote industrial structure upgrading and technological innovation and guide market players to establish green development concepts to gradually build an environmentally friendly, circular model economy to enhance the overall green development capacity of the region.

Green credit is regarded as an important means to promote sustainable growth. Based on the provincial panel dataset of China from 2007 to 2017, this paper investigates the dual impacts of green credit on the economy and environment, and it establishes mediating effect models to analyze the Porter hypothesis. The results show that the green credit policy significantly improves economic performance and reduces pollutant emissions. The above results are robust to employing methods with alternative variables and instrumental variables. Second, the green credit policy contributes to innovation; that is, the green credit increases the innovation scale and improves innovation efficiency. The results of mediating effect models suggest that the Porter effect of green credit can be achieved by improving innovation efficiency. The findings of the current study indicate that the green credit policy helps achieve the win–win situation for economic goals and environmental targets.

The effective design of green financial policies is crucial for balancing the operational pressures of heavily polluting enterprises with the goal of sustained carbon emission reduction. This study investigates the impact of the Green Finance Reform and Innovation Pilot Zone (GFRIPZ) policy by employing a multi-period difference-in-differences (DID) model based on firm-level panel data from 2012 to 2021, covering A-share listed enterprises in Shanghai and Shenzhen. The results show that GFRIPZs significantly reduced carbon emissions in pilot regions, with heterogeneous effects observed across enterprise types—particularly among large enterprises, state-owned enterprises, and those located in financially developed areas. To uncover the underlying mechanisms, we compare two behavioral responses: green innovation, marked by long-term investment in green technologies, and expedient compliance, involving short-term, strategic compliance behaviors. Our findings indicate that GFRIPZs did not effectively promote green innovation. Instead, it has encouraged a shift from productive capital investment toward un-productive, symbolic actions aimed at fulfilling policy requirements. These responses risk undermining the long-term objective of green transformation and may contribute to a broader shift from real economic activity toward speculative or less productive investments, raising concerns about the quality and sustainability of the low-carbon transition.

As the green bond market in China develops and its institutional structure improves, the green bond has emerged as a pivotal element within the broader framework of the green financial system. We focus on bond issuers in China’s A-shares from the years 2010 to 2021 and explore green bond issuance and the spillover effect of green technology innovation under the market attention perspective. Findings are that: (1) Green bond issuance can produce the spillover effect in the industry and significantly enhance peer enterprises’ green technology innovation. (2) From the viewpoint of market attention, analyst attention can significantly enhance the spillover effect of green bond issuance within the industry. The same is true for media attention and investor attention. (3) Further research shows that within the same industry, the spillover effect is more pronounced for state-owned enterprises, large-scale enterprises, and enterprises in regions with higher levels of green financial development. For the booming development of China’s green bond market and the sustainable development of enterprises, this paper provides theoretical and practical foundations.

As the concept of balancing environmental protection and maintaining sustainable economic development has been widely recognized, the green bond is assuming an increasingly significant role within China’s financial market. We utilize the data from China’s A-share listed enterprises that issued bonds in the period 2010 to 2021 and try to examine whether and how green bond issuance facilitates the spillover effect of green technology innovation in industry. The results show that: (1) Green bond issuance can generate a spillover effect, greatly enhancing green technology innovation within the industry. (2) The spillover effect of green technology innovation from green bond issuance within an industry is more pronounced for state-owned enterprises, and relatively weaker for enterprises in Northeast China in the same industry. Relative to non-high-pollution industries, high-pollution industries reinforce the spillover effect. (3) Financing cost and agency cost are important influencing mechanisms for green bond issuance to improve peer enterprises’ level of green technology innovation. Overall, the results provide theoretical support for encouraging the market for green bonds to maintain their development over the long term and for effectively promoting the transformation of the economy and society to a green and low carbon one.
