Environmental judicial protection and urban green technology innovation: evidence from China’s environmental public interest litigation pilot

Abstract

ABSTRACT Environmental justice is an important part of the environmental governance system. We use the exogenous shock of the environmental public interest litigation (EPIL) pilot implemented by the Chinese government in 2015 to construct a quasi-natural experiment and employ the difference-in-differences (DID) model to examine the impact and its mechanisms of environmental judicial protection on urban green technology innovation (GTI) with the help of the panel data of 274 cities in China from 2011 to 2019. The results show that the EPIL policy can significantly promote urban GTI. Mechanism tests reveal that the EPIL policy can induce urban GTI by raising public environmental attention (PEA) and strengthening the application of digital technology (DE). Heterogeneous analyses indicate that the promoting effect is more significant in eastern cities, southern cities, cities with higher administrative levels, larger cities, and cities with higher economic development levels. Our study not only enriches the relevant literature in the field of ‘law and economics’, but also provides a reference for policymakers to scientifically implement EPIL policy.
