Positive impacts of green finance on environmental protection investment: Evidence from green finance reform and innovations pilot zone

Abstract

After long-term development, the global economic level has improved significantly, but environmental issues generated by early extensive development seriously threaten the survival of human beings. China, in particular, urgently needs to promote sustainable development through green finance policies. For this reason, this paper regards the 2017 eight pilot zones in five provinces for green finance reform and innovations (GFRIs) as a quasi-natural experiment, and explores whether it can encourage investment in environmental protection in heavily polluting enterprises by using difference-in-differences-in-differences (DDD) model. The paper finds that: First, GFRIs can bolster investment in environmental protection in heavy polluting enterprises. The results remain consistent after several robustness checks, covering the placebo test, PSM-DID test and so on. Second, mechanism tests find that the policy promotes environmental protection investment by alleviating financing constraints and cutting financing costs. Third, heterogeneity analysis shows that the promotion effect of GFRIs on environmental protection investment is more pronounced for provinces with higher percentages of secondary industry GDP, large-scale enterprises, and enterprises with better ESG management. This paper demonstrates the beneficial influence of GFRIs on promoting the transformation of heavy polluting enterprises and provides suggestions for the improvement of such policies.
