Local governments and enterprises are two important actors in China's environmental governance system. A better understanding of the interaction between corporate environmental responsibility (CER) and governmental environmental responsibility (GER) will help to enhance the collaboration between corporations and the government, craft a good environmental governance system, and achieve coordinated development of economic development and environmental protection. This paper divides GER into three types: policymaking responsibility, implementation responsibility, and supervisory responsibility. Based on panel data on Chinese manufacturing companies listed during the period 2012-2017, this paper analyzes the relationship between GER and CER and explores the impact of the collaboration between the two on regional environmental pollution. The research results show the following: (1) in China, policymaking responsibility significantly promotes CER, whereas implementation responsibility has a significant negative impact on CER, and supervisory responsibility has no significant influence. (2) The collaboration between GER and CER effectively reduces solid waste discharge in a region but does not significantly reduce SO 2 emissions or wastewater discharge.
