This study examines the impact of strategic alliances on corporate green innovation. We find that strategic alliances significantly promote corporate green innovation. Mechanism tests indicate that strategic alliances promote green innovation through channels of attracting market attention, alleviating agency problems, and stimulating collaborative innovation. Heterogeneity analysis demonstrates that the effects of strategic alliances are more pronounced for firms in areas with stringent environmental regulations and a favorable business environment, and firms facing intense product market competition. The findings provide new insights into the green transformation and upgrading of enterprises.

This paper examines the spillover effect of environmental regulations on firms’ green technological innovation, from the perspective of supply chain relationships. Analyzing data from Chinese listed companies, we find that the average environmental regulatory pressure faced by the client firms of a supplier firm enhances the green patent applications filed by the supplier firm, indicating that environmental regulatory pressure from clients spills over to suppliers. When the industries of suppliers are more competitive or the proportion of their sales from the largest client is higher, suppliers feel more pressured to engage in green innovation, resulting in more green patent applications. Thus, via their negotiation power, client firms can prompt supplier firms to innovate to meet their demand for green technologies. Finally, we show that this effect is particularly pronounced when supplier firms are located in highly marketized regions, receive low R&D government subsidies, or have high ESG ratings.

Comprehensive evaluation and identification of the critical regulatory determinants of carbon emission efficiency (CEE) are very important for China’s low-carbon transition. Accordingly, this paper first employs an undesirable global super-hybrid measure approach to calculate the CEE of China’s iron and steel industry (ISI). We then further use spatial error and threshold regression models to examine the spatial and non-linear effects of heterogeneous environmental regulations on CEE, respectively. Our empirical results show that (1) CEE varies significantly across China’s regions, with the eastern region having the highest CEE score, followed by the western and central regions, with the northeast region ranking the lowest; (2) command-and-control and market-incentive regulations both promote CEE, whereas the public participation approach does not significantly contribute to performance gains; (3) all three types of environmental regulations exhibit a non-linear threshold effect on CEE; (4) openness level, technological progress, and industrial concentration enhance efficiency gains, while urbanization level exerts a negative impact on CEE. Our findings have important implications for the design of environmental regulations.

Exploiting the unexpected Central Environmental Inspections (CEI) in China as a quasinaturalexperiment, we find that public firms in polluting industries experience significant gains in both profitability and market valuation after the regulatory shock, relative to firms in nonpolluting industries. The outperformance of public firms can be explained by the retreat of their private competitors, many shut down due to poor environmental performance. Because firms seeking public listing are required to meet high environmental standards, CEI significantly strengthen public firms’ competitive position, leading to increased sales growth and market share. Moreover, the outperformance is more pronounced for firms with more eco-friendly technologies, consistent with strict environmental regulations increasing the marginal benefit of these technologies. We provide novel evidence of the bright side of environmental regulation by highlighting the importance of industry dynamics.

Using the data of Chinese listed firms from 2003-2020, this study applies a System GMM estimation approach to document that high local government ecological concerns increase a firm’s stock price crash risk. This finding remains consistent after addressing endogeneity issues and undergoing robustness checks. This study also reveals that the implementation of the new environmental protection law in 2015 mitigates the relationship between local government ecological concerns and stock price crash risk. Further analyses indicate that stricter environmental regulation and high subsidies, as well as enhanced corporate social responsibility and governance, can effectively alleviate the adverse effect of local government ecological concerns on stock price crash risk. In addition, we note that the influence of local government ecological concerns on stock price crash risk is more significant in the eastern region, heavily polluting industries, and non-SOEs. Lastly, the research identifies two potential channels through which local government ecological concerns can impact stock price crash risk by reducing the quality of information disclosure and intensifying investor disagreement.

Taking the Stock Connect scheme as an exogenous shock based on data of China’s Ashare non-financial listed companies from 2009 to 2021, we identify the causal effect of stock market liberalization on green innovation. The baseline result based on a staggered difference-indifferences (DID) model suggests that stock market liberalization promotes corporate green innovation and this effect is similar to the green benefits of China’s mandatory environmental regulations. The results are robust to various checks, including the parallel trend tests, placebo tests, and the heterogenous time-varying treatment test based on Bacon decomposition and the DIDM approach. The enhanced continuity of corporate financing, improved corporate green governance and increased firm external technological collaboration are three plausible channels that allow stock market liberalization to promote corporate green innovation. Moreover, the effect is more significant for clean firms, non-SOEs, and firms in a good institutional environment. Further analysis suggests that the green innovation-enhancing effects of stock market liberalization are more likely to be high-quality innovation. Our paper provides new insights into understanding the green benefits of stock market liberalization and achieving sustainable economic development in developing countries.

Based on the perspective of human capital and technology R & D regulation, this paper adopts the unexpected output super efficiency SBM model to calculate the ecological efficiency of digital enterprises in 30 provinces in China from 2010 to 2019, analyzes its spatial correlation, and empirically explores the driving factors of the ecological efficiency of Chinese digital enterprises under the role of environmental regulation. The results show that during the research period, the overall level of ecological efficiency of digital enterprises in China can be divided into three stages: gentle stage (2010-2014), trough stage (2014-2017) and fluctuation stage (2017-2019), and the eastern region > the central region > the western region; The ecological efficiency of China's digital enterprises as a whole shows a ladder like evolution law of decreasing from southeast to northwest, with significant spatial agglomeration and "block" characteristics; Environmental regulation has a lag effect on the ecological efficiency of digital enterprises, and the lag period inhibits the improvement of the ecological efficiency of digital enterprises; The level of human capital and the level of scientific and technological research and development have significant threshold characteristics. When the level of human capital is used as a threshold variable, the impact of environmental regulation on the ecological efficiency of digital enterprises is "U" shaped. When the level of scientific and technological research and development exceeds a certain threshold, environmental regulation has a negative impact on the ecological efficiency of digital enterprises.

Using the firm-level data of the Chinese industrial sector from 1998 to 2010, this study investigates the impact of the previous environmental protection experience of prefecture-level Communist Party secretaries on the COD regulation within the secretaries’ respective jurisdictions. The study finds that the secretaries’ previous environmental protection experience has reduced the COD discharge intensity. The duration of the previous environmental protection experience is selected as an instrumental variable and the endogeneity is further addressed; the research conclusion remains unchanged. However, this negative impact only lasts for two years and presents an unclear long-term impact. The negative effect on COD discharge intensity caused by the previous environmental protection experience is affected by the mandatory regulation pressure from the central government and the overall polluting density of the sub-sectors. Secretaries with previous environmental protection experience do not reduce the COD discharge intensity by using the punishment mechanism of increasing sewage charges. The secretaries, instead, encourage enterprises to use clean production technology, save water resources, and reduce the produced COD level. Also, the secretaries place an emphasis on the treatment of wastewater pollutants, thus reducing the COD discharge intensity. The conclusions of this study can provide decisionmaking reference for the selection and training of local officials, with the goal of environmental regulation.

The caliber of export products is a microcosmic reffection of economic development quality. This study seeks to elucidate the inffuence of environmental regulation on product quality, integrating the role of the skill premium as shaped by environmental regulation within a Dixit-Stiglitz CES production function model. Additionally, we empirically scrutinize the interplay between environmental regulation, skill premium, and product quality, utilizing Chinese customs export data in conjunction with data from listed companies spanning 2003-2015. The conclusions drawn from our theoretical analysis and empirical veriffcation reveal an inverted U-shaped relationship between environmental regulation and product quality, which is tempered by the skill premium. Moreover, a signiffcant positive correlation exists between environmental regulation and the skill premium. Similarly, the relationship between the skill premium and product quality manifests an inverted U-shape. Notably, an elevated skill premium markedly bolsters the enhancement of product quality through green innovation. These insights underscore the need for balanced environmental regulations and strategic investment in skilled labor to augment product quality. This serves as a valuable compass for policymakers and businesses endeavoring for green innovation and high-quality, sustainable economic growth.

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.
