随机抽查环境监管制度对企业绿色创新的影响

The Impact of Random Inspection of the Environmental Supervision System on Corporate Green Innovation

随机抽查环境监管制度是我国环境治理领域的一项重大创新。基于2010—2021年A股上市公司的绿色创新数据,采用双重差分法考察了这项制度对企业绿色创新的影响。研究结果表明,随机抽查环境监管制度显著地推动了企业绿色创新,且这种影响具有较强的持续性。机制分析结果显示,该制度通过增强政府的环境监管压力和企业的环境合规压力,提升了企业绿色创新,分别体现了规制效应和威慑效应。拓展性分析发现,随机抽查环境监管制度对企业绿色创新的促进作用在国有企业、融资约束较小、代理成本较低以及知识产权保护较强地区的企业中表现得更明显。此外,随机抽查环境监管制度不仅显著地提升了企业的环境绩效,展现了其环境有效性,同时也显著地改善了企业的经济绩效,展现了其经济有效性。因此,政府部门应积极推进随机抽查环境监管制度,强化知识产权保护,并采取措施缓解企业在绿色创新过程中面临的融资约束。同时,企业还应致力于完善公司治理机制,降低代理成本,以进一步促进绿色创新水平的提升。

The random inspection of the environmental supervision system is an important innovation in the field of China's environmental governance.Based on the green innovation data of A-share listed companies from 2010 to 2021,this paper explores the impact of the random inspection of the environmental supervision system on corporate green innovation by using the difference-in-differences method.The findings show that the random inspection of the environmental supervision system can significantly promote corporate green innovation,and this positive effect has a strong continuity.The mechanism analysis uncovers that this system enhances the green innovation of enterprises by strengthening the environmental regulatory pressure of the government and the environmental compliance pressure of enterprises,reflecting both regulatory and deterrent effects.The results of the extended analysis indicate that the promotion effect of the environmental supervision system on green innovation in enterprises through random sampling is more evident in the state-owned enterprises and the enterprises located in the areas with less financing constraints,lower agency costs,and stronger intellectual property protection.In addition,the random inspection of the environmental supervision system not only significantly improves the environmental performance of enterprises and demonstrates their environmental effectiveness,but also significantly improves their economic performance and demonstrates their economic effectiveness.Therefore,it is necessary for the government departments to actively carry out the random inspection of the environmental supervision system,strengthen intellectual property protection and take measures to alleviate the financing constraints faced by enterprises during the process of green innovation.Meanwhile,enterprises should further improve the corporate governance mechanism and reduce agency costs,so as to promote the level of corporate green innovation.
