数字化转型对制造业企业绿色创新的“双刃剑”效应

The"Double-edged Sword"Impact of Digital Transformation on Green Innovation of Manufacturing Enterprises

在“双碳”目标约束下,制造业亟需依托绿色创新有效促进绿色经济发展。文章基于我国A股制造业上市企业2007—2020年面板数据,实证分析数字化转型对制造业企业绿色创新的影响。研究结果表明:(1)数字化转型与企业绿色创新水平、绿色创新质量之间均存在倒U形关系;相较于绿色创新水平,绿色创新质量达到最优需要的数字化转型程度更高。(2)数字化转型能够通过成本效应、信息效应、资源效应作用于绿色创新水平与绿色创新质量。(3)数字化转型与绿色创新水平、绿色创新质量之间的倒U形关系在国有企业、非重污染行业企业、东部地区企业、高市场化水平地区的企业中更显著。基于此,今后应推进制造业企业合理引进与发展绿色技术,进一步激发非国有企业创新活力,通过数字化转型带动绿色创新。

Under the constraints of carbon peaking and carbon neutrality goals,the manufacturing industry urgently needs to re-ly on green innovation to effectively promote the development of green economy.The paper is based on panel data of A-share manufacturing listed companies in China from 2007 to 2020,and empirically analyzes the impact of digital transformation on green innovation in manufacturing enterprises.The research results indicate that,firstly,there is an inverted U-shaped relation-ship between digital transformation and the level and quality of green innovation in enterprises;Compared to the level of green innovation,achieving optimal quality of green innovation requires higher levels of digital transformation.Secondly,digital trans-formation can affect the level and quality of green innovation through cost effects,information effects,and resource effects.Thirdly,the inverted U-shaped relationship between digital transformation,green innovation level,and green innovation quali-ty is more significant in state-owned enterprises,non heavily polluting industry enterprises,enterprises in the eastern region,and high marketization level areas.Based on this,in the future,manufacturing enterprises should promote the rational introduc-tion and development of green technology,further stimulate the innovation vitality of non-state-owned enterprises,and drive green innovation through digital transformation.
