ESG growth catalyst: China's Central Bank collateral framework expansion

Area of Science:

• Environmental Economics
• Corporate Finance
• Sustainable Development

Background:

• Environmental, Social, and Governance (ESG) criteria are crucial for corporate sustainability.
• China's central bank expanded its Medium-Term Lending Facility (MLF) collateral to include green bonds in June 2018.
• This policy aimed to alleviate financing constraints and foster green innovation.

Purpose of the Study:

• To investigate the impact of China's Expanded Pledge Framework Policy (EPCF) on corporate ESG performance.
• To determine if the EPCF alleviates financing constraints and promotes green innovation.
• To analyze the causal relationship between the EPCF and corporate ESG performance.

Main Methods:

• Utilizing a quasi-natural experiment design with the EPCF.
• Employing difference-in-differences (DID) and other econometric methods.
• Analyzing panel data of China's A-share listed companies from 2014 to 2022.

Main Results:

• The EPCF significantly improves corporate ESG performance by easing financing constraints and promoting green innovation.
• Implementation of the EPCF leads to an average improvement of 0.02 units in relative ESG performance.
• The policy shows a greater positive impact on non-heavy polluting enterprises and in regions with higher marketization and coastal areas.

Conclusions:

• The EPCF is an effective policy tool for enhancing corporate ESG performance in China.
• While green bonds alone have limited impact, the EPCF amplifies their positive effect.
• Policy effectiveness is context-dependent, being stronger in more marketized and coastal regions.
