As an important component of green finance, green bonds are still in their infancy in China and require more policy support from the government. The ESG (Environmental, Social, and Governance) evaluation system, as a crucial tool for assessing corporate green development and sustainability, plays a significant role in enhancing corporate sustainable management capabilities and promoting the transformation of the economy towards green and low-carbon directions, especially as China pursues its goals of carbon peak and neutrality. The focus of this study is on the impact of corporate green bond issuance on ESG ratings. Based on data from 2010 to 2022, with corporate green bond issuance as the explanatory variable, corporate credit scores and financialization as moderating variables, and corporate ESG ratings as the dependent variable, this paper employs fixed-effects models, moderation effect models, heterogeneity analysis, and mechanism analysis to explore the promoting effect of core variables on corporate ESG ratings and their channels of action. The results indicate: 1) The issuance of green bonds by companies has a relatively significant positive effect on ESG ratings; 2) Corporate credit scores and financialization can effectively enhance the promoting effect of green bonds on corporate ESG ratings; 3) In terms of industry pollution levels, the issuance of green bonds has a more pronounced effect on heavily polluting enterprises, and in terms of property rights, the issuance of green bonds has a more significant impact on the ESG performance of non-state-owned enterprises.
