摘要
为探究产业集聚与企业绿色创新之间的关系,基于2011—2021年上市公司的绿色专利数据,将中国地级市产业集聚指数匹配至企业层面,运用固定效应模型对产业集聚程度与企业绿色创新的关系进行实证检验。研究发现,城市产业集聚程度有利于促进企业绿色创新,企业ESG表现正向调节二者关系。进一步通过异质性分析发现,产业集聚程度对企业绿色创新的促进作用存在区域异质性、企业异质性和行业异质性。区域异质性分析结果显示,产业集聚对企业绿色创新的促进作用在中西部和东部地区显著,但是对中西部地区的企业绿色创新边际贡献更大;产业集聚对企业绿色创新的促进作用在环保重点城市显著而在非环保重点城市不显著。企业异质性分析发现产业集聚对非国有企业、小规模企业绿色创新的影响显著。行业异质性分析表明,产业集聚对企业绿色创新的影响在高技术行业显著。研究为提高企业绿色创新提供了理论基础,为政府制定决策提供依据,有利于企业有效利用产业集聚所带来的知识流动、企业合作等机遇,提高自身绿色创新水平从而获得竞争优势。
In order to explore the relationship between industrial agglomeration and enterprise green innovation,based on the green patent data of listed companies in the decade from 2011 to 2021,the industrial agglomeration index of China's prefecture-level cities was matched to the enterprise level,and then the fixed-effect model was used to empirically test the relationship between industrial agglomeration degree and enterprise green innovation.The empirical results indicate that the degree of urban industrial agglomeration is conducive to promoting enterprise green innovation,and ESG performance positively adjusts the relationship between industrial agglomeration degree and enterprise green innovation.Furthermore,through heterogeneity analysis,it is found that there is regional heterogeneity,enterprise heterogeneity and industry heterogeneity in promoting green innovation of enterprises.The results of regional heterogeneity analysis show that the role of industrial agglomeration in promoting enterprise green innovation is significant in the central and western regions,but industrial agglomeration has a greater contribution of enterprise green innovation in the central and western regions than eastern regions.The role of industrial agglomeration in promoting green innovation of enterprises is significant in key cities of environmental protection,but not in non-key cities of environmental protection.The analysis of enterprise heterogeneity shows that industrial agglomeration has a significant impact on the green innovation of non-state-owned enterprises and small-scale enterprises,but it is not significant in state-owned enterprises and large-scale enterprises.The analysis of industry heterogeneity according to industry groups shows that the impact of industrial agglomeration on enterprise green innovation is significant in high-tech industries but not in non-high-tech industries.The research conclusion provides a theoretical basis for improving the level of enterprise green innovation and provides a basis for the governm
