绿色技术创新对企业竞争力的影响效应研究

Research on the Influence of Green Technology Innovation on Enterprise Competitiveness

采用2010—2019年沪深A股上市公司的数据,实证检验了绿色技术创新对企业竞争力的影响。研究发现,绿色技术创新对企业竞争力有显著的正向影响,在采用工具变量法、替换核心解释变量和被解释变量以及对核心解释变量采用动态效应后,结果依然稳健;中介机制检验表明,企业开展绿色技术创新能够提升企业全要素生产率以实现成本领先与标新立异,使其具备绿色特征的竞争优势;产融结合负向调节了绿色技术创新对企业竞争力的促进作用;在非国有企业以及处于东部地区企业中,绿色技术创新对企业竞争力的提升作用更大。

An empirical test has been made of the impact of green technology innovation on corporate competitiveness by using data from A-share listed companies in Shanghai and Shenzhen from 2010 to 2019.Research has found that firstly,green technology innovation has a significant positive impact on corporate competitiveness in that the results remain robust after using instrumental variable method,replacing the core explanatory variable and the dependent variable,and applying dynamic effects to the core explanatory variable.Secondly,the intermediary mechanism test shows that the implementation of green technology innovation helps to enhance the total factor productivity of enterprises so as to achieve a low-cost leadership and innovation,thus granting them a competitive advantage with green characteristics.Thirdly,the combination of industry and finance negatively helps to regulate the promoting effect of green technology innovation on the competitiveness of enterprises.Fourthly,green technology innovation has a greater impact on competitiveness enhancement of non-state-owned enterprises and those located in eastern regions.
