摘要
数字化与绿色化协同发展是经济全面转型升级的内在需求。当前研究主要关注数字化对低碳发展的影响,低碳转型如何影响企业数字化这一问题还未得到充分关注。构建理论模型探究了低碳城市试点影响数字化的内在逻辑,利用2005-2021年城市和上市公司数据,结合低碳城市试点政策的准自然实验,构建双重差分模型考察了该政策对企业数字化的影响。研究发现,低碳城市试点显著促进了企业数字化,在一系列稳健性检验后结论依然稳健,并且这一影响在不同企业、不同行业和不同区域中存在明显差异,具体表现为低碳城市试点对中小型企业、国有企业、高碳密度行业和工业专业化程度更高的地区有更显著的促进作用。机制分析显示,低碳城市试点通过缓解融资约束、促进产出绿色化和增加绿色产品需求从而促进企业数字化。此外,成本-收益分析表明低碳城市试点政策引发的企业数字化收益大于数字化成本。结论从数字化视角证实了低碳城市试点带来环境保护和经济发展的双重红利,也为低碳转型和数字化共生发展的政策制定提供了启示。
The coordinated development of digitalization and greening is required for comprehensive economic transformation and upgrading.The existing literature focuses on the impact of digitalization on low-carbon development but few studies consider how low-carbon transformation affects enterprise digitalization.This paper builds a theoretical model to theoretically reveal the internal logic of low-carbon city pilot policy affecting enterprise digitalization,and constructs a difference-in-differences model to verify the relationship between the two based on prefecture-level city data and listed company data from 2005 to 2021.The results show that the policy has significantly promoted the digitalization of enterprises,and this finding remains stable after a series of robustness tests.However,the impact is significantly different depending on enterprise characteristics,industries,and regions;there is a more significant promotion effect on small and medium-sized enterprises and state-owned enterprises as well as in high-carbon-density industries and regions with greater industrial specialization.The mechanism analysis shows that the low-carbon city pilot promotes the digitalization of enterprises by alleviating financing constraints,promoting green output,and increasing the demand for green products.The cost-benefit analysis shows that the benefits of enterprise digitalization as a result of the low-carbon city pilot are greater than the costs of digitalization.The findings confirm that the low-carbon city pilot brings dual dividends of environmental protection and economic development through digitalization and also support the formulation of policy for low-carbon transformation and digital symbiotic development.
