【摘要】 推进企业数字化转型是实现经济高质量发展的必然要求，以低碳城市试点政策为代表的命令控制型环境规制在“数字中国”的建设中发挥着重要作用。鉴于此，本文以低碳城市试点政策为切入点，基于2007—2021年中国A股上市公司的数据，采用交错双重差分模型实证检验了命令控制型环境规制政策对企业数字化转型的影响及作用机制。研究发现，低碳城市试点政策的实施能够有效倒逼企业数字化转型，传导机制为碳排放水平降低效应、绿色技术创新促进效应、融资约束缓解效应和董事海外背景调节效应。该结论在经过一系列稳健性检验后依然成立。异质性分析显示，政策效应的发挥会因产业类型和行业类型的差异而呈现异质性。进一步分析发现，该政策在推动数字化转型的同时还能够促进企业扩大规模，推动试点地区经济发展，对试点城市的经济贡献度为0.0184%。本文的研究结论对于政府如何利用宏观调控手段倒逼企业数字化转型，实现经济“绿色化”和“数字化”协同发展具有重要启示。更多还原

【Abstract】 Promoting digital transformation of enterprises is an inevitable requirement for achieving high-quality economic development. Command-and-control environmental regulations represented by low-carbon city pilot policies play an important role in the construction of “digital China”. Based on the pilot policy of low-carbon cities as the entry point, data from China’ A-share listed companies from 2007 to 2021 was used to test the impact and mechanism of command-and-control environmental regulation policies on enterprises’ digital transformation by the staggered differential model. The results show that the implementation of pilot policies in low-carbon cities can effectively force enterprises to transform digitally by reducing carbon emission level, promoting green technology innovation, easing financing constraints and adjusting from directors’ overseas background. The conclusion is still valid after a series of robustness tests. The heterogeneity analysis shows that the policy effect will depend on the difference of industry type and category of employment. Further analysis shows that while promoting digital transformation, the policy can also promote the expansion of enterprises and the economic development of pilot areas. The economic contribution of pilot cities is 0.0184%. The research conclusions of this article have important implications for how the government use macro-control means to force enterprises to digital transformation and realize the coordinated development of “green” and “digital” economy.更多还原
