Study on the Influence Mechanism of Environmental Management System Certification on Enterprise Green Innovation.

Improving the green technology innovation capability of enterprises is an important way for industrial enterprises to improve product quality and production efficiency and reduce industrial pollution and energy consumption. Based on the Porter hypothesis, this paper took the data of listed companies of the heavy polluting industry in Chinese A-shares from 2011-2018 as a study sample, and a difference-in-differences (DID) model was constructed to explore the impact of environmental management system certification (EMSC) on enterprises' green innovation. This paper also studied the differential impact between the EMSC and enterprises' green innovation from the perspective of enterprise heterogeneity.
