数字经济赋能长江经济带绿色发展:机制、异质性及策略

Empowering Green Development in the Yangtze River Economic Belt with Digital Economy:Mechanisms,Heterogeneity and Strategies

数字经济作为加快发展新质生产力的重要措施,对于促进产业绿色化转型、提升绿色全要素生产率发挥着重要作用。以2011—2022年长江经济带108个地级市的面板数据为研究对象,深入探讨数字经济对长江经济带绿色全要素生产率的提升路径,结果表明:第一,数字经济能显著促进绿色全要素生产率的提升;第二,产业结构升级、人力资本以及绿色技术创新在两者关系中起到了重要的机制传导作用;第三,异质性检验结果显示,数字经济对提升长江经济带下游地区绿色全要素生产率的促进作用更加明显。面对长江经济带在利用数字经济推动绿色发展时仍面临的区域发展不平衡、产业结构调整难度大和绿色技术创新转化效率低等问题,建议通过加强区域协调发展、优化数字基础设施、激励企业创新及培养高端人才等策略,实现长江经济带绿色全要素生产率的全面提升。

The digital economy plays a crucial role in accelerating the development of new quality and vitality,promoting the green transformation of industries,and enhancing gtfp.This study focuses on the panel data of 108 prefecture-level cities in the Yangtze River Economic Belt from 2011 to 2022 to explore how the digital economy enhances gtfp.The findings indicate that:first,the digital economy significantly contributes to improving gtfp;second,upgrading industrial structure,investing in human capital,and innovating green technology are key mechanisms in this relationship;third,heterogeneity testing reveals that the digital economy has a more pronounced impact on promoting gtfp in the lower reaches of the Yangtze River Economic Belt.Facing the problems of unbalanced regional development,difficult industrial structure adjustment and low efficiency of green technology innovation transformation,the Yangtze River Economic Belt still faces in promoting green development through digital economy,it is suggested to strengthen regional coordination development,optimize digital infrastructure,encourage enterprise innovation and cultivate high-end talents,so as to realize the comprehensive improvement of gtfp of the Yangtze River Economic Belt.
