摘要:

文章依据长江三角洲城市经济协调会扩容事件,基于2007—2019年A股上市公司绿色专利申请数据,使用倾向得分匹配—双重差分模型实证检验区域一体化对企业绿色技术创新的政策效应。研究发现:区域一体化能有效促进企业绿色技术创新,不同类别的绿色技术创新均受正向影响;宏观层面渠道可通过缓解劳动力错配、促进区域金融发展、加速市场化进程、提升城镇化水平促进企业绿色技术创新,微观层面渠道可通过缓解企业融资约束和获得政府补助促进企业绿色技术创新。区域一体化促进企业绿色技术创新的异质性效应在不同所有制属性、地区和时间跨度上有所显现,具体表现为对国有企业、大规模企业及新加入城市内企业的促进作用更强。今后应持续推动区域一体化协调发展、完善具有针对性的企业扶持制度、强化政企合作,进一步促进企业绿色技术创新。

Abstract:

Based on the expansion of regional integration in the Yangtze River Delta region and the green patent application data of A-share listed companies from 2007 to 2019, this paper empirically tests the policy effect of regional integration on enterprise green technology innovation using the propensity score matching double difference model (PSM-DID). Research has found that regional integration can effectively promote green technology innovation in enterprises, and different types of green technology innovation are positively affected; The outer mechanism can promote green technology innovation in enterprises by alleviating labor mismatch, improving regional financial development level, deepening marketization process, and promoting urbanization level. The inner channel can alleviate financing constraints and obtain government subsidies to promote green technology innovation in enterprises. Heterogeneity effects induce green technology innovation capabilities in different attributes, regions, and time spans, with state-owned enterprises, large-scale enterprises, and newly entered cities having a stronger promoting effect. Based on the research findings of this paper, policy recommendations are provided to continuously promote the coordinated development of regional integration, strengthen targeted support for enterprise systems, and promote government enterprise cooperation.

Key words: Yangtze River Delta region, regional integration, enterprise green technological innovation, PSM-DID
