【摘要】 文章以2015—2019年中国石化行业337家上市公司为研究样本,运用双重差分模型验证了当期环境规制对后一期企业绩效的正向影响。进一步的中介效应检验发现,环境规制主要通过技术创新促进企业绩效的提高,从而验证了中国石化行业"波特假说"的存在。此外文章还发现环境规制影响企业绩效的效果及作用机制存在显著的区域差异,东、中部地区表现出显著正向影响,均支持"波特假说",西部地区则影响不明显。基于上述研究,文章认为促进石化行业的绿色低碳发展,需进一步加大石化行业生态环境保护的政策实施力度、促进石化行业企业的科技投入并注重区域差异。更多还原

【Abstract】 The paper used 337 listed companies in China’s petrochemical industry from 2015 to 2019 as research samples to verify the positive impact of current environmental regulations on the company’s performance in the subsequent period by differencesin-differences method. The further test of the intermediary effect found that environmental regulations mainly improve enterprise performance through technological innovation, thereby verifying the existence of the Porter Hypothesis in China’s petrochemical industry. In addition, the paper also found that there are significant regional differences in the effect and mechanism of environmental regulation on enterprise performance. The eastern and central regions showed significant positive effects, and both supported the Porter Hypothesis, while the western regions had no obvious influence. To promote the green and low-carbon development of the petrochemical industry, it is necessary to further increase the implementation of environmental protection policies in petrochemical industry, promote the the scientific and technological investment of petrochemical enterprises and focus on regional differences.更多还原
