绿色化能否带动数字化：来自气候适应型城市建设的证据

Can Greening Drive Digitalisation: Evidence From Climate-adaptive Urban Development

摘要:

双化协同发展，旨在以数字化赋能绿色化，以绿色化带动数字化的可持续发展，是新时代中国经济社会发展的必然选择与核心战略路径。本文聚焦于绿色化带动数字化这一条路径，基于2012－2023年A股上市企业数据,以气候适应型城市建设试点政策的实施为“准自然实验”，使用标准双重差分法考察该政策的实施对企业数字化转型的因果效应。研究发现，气候适应型城市建设试点政策的实施显著促进了企业数字化转型，且这一政策在国有企业、管理层权力小的企业、非高新技术行业、重污染行业、高能耗压力城市和省会城市的促进效果更为明显。机制检验发现，气候适应型城市建设试点政策主要通过数字基础赋能效应、规制驱动效应和研发激励效应促进企业数字化转型。进一步分析表明，地方政府数字关注度、政府补助和人才引进强度均能够与气候适应型城市建设试点政策产生协同作用，强化了气候适应型城市建设试点政策对企业数字化转型的促进作用。本研究为气候适应型城市建设试点政策的进一步完善提供参考与借鉴。

Abstract:

The coordinated development of digitalization and greenization aims to empower greenization with digitalization and drive the sustainable development of digitalization through greenization. It is an inevitable choice and core strategic path for China"s economic and social development in the new era. This paper focuses on the path of greenization driving digitalization. Based on the data of A-share listed companies from 2012 to 2023, it takes the implementation of the pilot policy for climate-adaptive city construction as a "quasi-natural experiment" and uses the difference-in-differences method to examine the causal effect of the pilot"s implementation on enterprises digital transformation. The research finds that the implementation of the pilot policy for climate-adaptive city construction significantly promotes enterprise digital transformation, and this policy has a more obvious promoting effect on state-owned enterprises, enterprises with less management power, non-high-tech industries, heavy-polluting industries, high-energy consumption pressure cities and provincial capital cities. Mechanism tests show that the pilot policy for climate-adaptive city construction mainly promotes the digital transformation of enterprises through the digital infrastructure empowerment effect, regulatory driving effect and R D incentive effect. Further analysis indicates that government digital attention, government subsidies and talent introduction intensity can work in synergy with the pilot policy for climate-adaptive city construction to jointly promote the digital transformation of enterprises. This research provides reference and inspiration for the further improvement of the pilot policy for climate-adaptive city construction.
