企业数字化转型、政策组合协同与企业绿色创新——基于环保与创新政策的交互视角

Enterprise Digital Transformation, Policy Mix Coordination and Enterprise Green Innovation—Based on the Interactive Perspective of Environmental Protection and Innovation Policy

摘要: 本文以2005~2023年中国A股上市公司为样本，构建多时点双重差分模型，考察数字化转型视角下环保与创新组合政策协同对企业绿色创新的影响效应及作用机制。研究发现：第一，数字化转型视角下双政策协同显著促进了企业绿色创新，且效果优于单一政策；第二，双政策协同主要通过数字赋能效应和人才集聚效应这两条路径发挥作用；第三，受数字化网络影响，双政策协同效应对周边150~200公里范围内的城市存在正向空间溢出效应。本文为理解数字化转型视角下双政策协同与企业绿色创新的关系提供了实证依据，并为优化政策组合提供了参考。

Abstract: Based on the sample of China’s A-share listed companies from 2005 to 2023, this paper constructs a multi-time difference-in-difference model to examine the impact and mechanism of the synergy of environmental protection and innovation portfolio policies on corporate green innovation from the perspective of digital transformation. The study found that: First, from the perspective of digital transformation, dual policy synergy has significantly promoted corporate green innovation, and the effect is better than a single policy; second, the dual policy synergy mainly plays a role through the two paths of digital empowerment effect and talent agglomeration effect. Thirdly, due to the influence of digital network, the synergistic effect of the two policies has a positive spatial spillover effect on the cities within the range of 150~200 km. This paper provides an empirical basis for understanding the relationship between dual policy coordination and enterprise green innovation from the perspective of digital transformation, and provides a reference for optimizing the policy mix.
