Does interest rate liberalization affect corporate green investment?

Abstract

This paper investigates the impact of interest rate liberalization on corporate green investment by taking the cancellation of the lower limit of the loan interest rate of financial institutions by the People's Bank of China in July 2013 as an exogenous quasi-natural experiment. We find that the interest rate liberalization will boost corporate green investment. Specifically, for every one standard deviation increase in interest rate liberalization, the enterprise green investment intensity increases by 9.6% of the sample standard deviation on average. Moreover, underlying mechanisms show that interest rate liberalization reform can improve corporate green investment by easing financing constraints, improving market competition, and reducing business risks. In addition, the impacts are more profound on enterprises facing higher environmental supervision intensity, lower attention of capital market, higher degree of regional marketization, and lower degree of financialization. Extended analysis show that interest rate liberalization will further promote the substantive innovation of green technology and improve environmental performance after enhancing the green investment of enterprises. This study contributes to playing the role of financial services in the green transformation of the economy.
