Corporate Environmental Protection Investment and Debt Financing Costs: Evidence from China

Corporate environmental protection investment is crucial for reducing pollution levels and controlling harmful substance emissions. We examine the relationship between corporate environmental protection investment and debt financing costs, utilizing a sample of A-share listed companies in China from 2011 to 2020. We find that debt financing costs are negatively related to corporate environmental protection investment. Green technology innovation and ESG performance are the main channels. Environmental regulations, air quality, and green finance impact the interplay between corporate environmental protection investment and debt financing costs. Moreover, our heterogeneity analysis underscores that enterprises facing looser financing constraints and low levels of pollution are more likely to mitigate debt financing costs by investing in environmental protection. The conclusion provides policy implications for guiding enterprises to consider environmental investment as a long-term strategy and provides a theoretical foundation for the government to enhance its guiding role.
