公众环境关注度对企业碳绩效水平的影响研究

The Impact of Public Environmental Concern on the Level of Corporate Carbon Performance

基于中国A股工业行业上市公司2011~2019年的数据,探讨公众环境关注度与企业碳绩效水平的关系。研究发现:公众环境关注度能够有效提升企业的碳绩效水平,在进行工具变量法等稳健性检验后,该结论依然成立。机制分析表明,公众环境关注度通过两条路径对企业的碳绩效水平产生积极影响,即促进企业绿色技术创新和优化地区能源消费结构。异质性检验表明,公众环境关注度对企业碳绩效水平的提升作用,在地方环境规制更强、低碳试点城市的企业、社会责任表现较差的企业中更加明显,且对不同产权性质的国企和非国企都发挥了显著影响。

This study explores the relationship between public environmental concern and the level of corporate carbon performance based on the data of Chinese A-share listed companies in the industrial sector from 2011 to 2019.The research finds that public environmental concern significantly improves the level of corporate carbon performance,and this conclusion remains robust after additional tests such as the instrumental variables approach.The mechanism analysis shows that public environmental concern improves the level of carbon performance in firms through two mechanisms.One is promoting green technological innovation in firms,and the other is optimizing the regional energy consumption structure.The heterogeneity analysis indicates that the impact of public environmental concern on the level of carbon performance is more pronounced for firms facing stronger local environmental regulations,located in low-carbon pilot cities,and with poorer social responsibility performance,while it exerts a significant effect on both SOEs and non-SOEs.
