数字产业集聚与制造业企业绿色转型

Digital Industry Agglomeration and the Green Transformation of Manufacturing Enterprises

摘要: 在“双碳”目标背景下，推动制造业企业绿色转型已成为实现经济高质量发展的重要路径。基于2013~2022年中国A股制造业上市公司数据，本文实证检验了数字产业集聚对制造业企业绿色转型的影响及其作用机制。研究结果表明，数字产业集聚能够显著促进制造业企业绿色转型，该结论在一系列稳健性检验后依然成立。机制检验结果显示，数字产业集聚可能通过促进知识溢出和吸引人才集聚两条机制在一定程度上推动制造业企业绿色转型，对污染型企业影响更为显著，并且该效应在东部地区表现更为强劲。本文的研究结论进一步表明，政府应当进一步推动数字产业集聚，建设多方面的绿色转型支持体系，并实施差异化政策。

Abstract: Against the backdrop of China’s “dual-carbon” goals, promoting the green transformation of manufacturing enterprises has become an important pathway to achieving high-quality economic development. Using data on Chinese A-share listed manufacturing firms from 2013 to 2022, this study empirically examines the impact of digital industry agglomeration on the green transformation of manufacturing enterprises and explores its underlying mechanisms. The results show that digital industry agglomeration significantly promotes the green transformation of manufacturing enterprises, and this conclusion remains robust after a series of robustness tests. Mechanism analysis suggests that digital industry agglomeration may facilitate the green transformation of manufacturing enterprises to some extent by promoting knowledge spillovers and attracting talent agglomeration, with a more pronounced effect observed in pollution-intensive firms. Furthermore, the effect is stronger in the eastern region. The findings further imply that the government should continue to promote the development of digital industry agglomeration, establish a comprehensive support system for green transformation, and implement differentiated policies.
