摘要: 在“数字中国”和“美丽中国”的建设进程中,本文以2011-2019年全国274个地级及以上城市的平衡面板数据为样本,在剖析数字经济自身特性的基础上,从作用机制与门槛效应两方面探讨了数字经济对城市绿色发展的影响。研究发现:数字经济显著促进了城市绿色发展,并且这种促进作用在东部城市、智慧城市试点城市以及知识产权保护力度强的城市中更为明显。进一步研究表明,数字经济可以通过推动经济结构服务化、激励绿色技术创新、提升公众环境关注度促进城市绿色发展。随着当前数字基础设施的广泛建设,社会用电量和碳排放不断增加,数字经济对城市绿色发展的的影响存在边际效应递减的非线性特征。本文的研究结论在积极推动城市拥抱绿色发展新范式的同时,也为构建集约化、低碳化的现代基础设施体系,实现数字化绿色化协同发展提供了有益借鉴。

Abstract: In the process of the construction of "Digital China" and "Beautiful China", this paper takes the balanced panel data of 274 cities at prefecture level and above in China from 2011 to 2019 as samples, and on the basis of analyzing the characteristics of digital economy itself, discusses the impact of digital economy on urban green development from two aspects of action mechanism and threshold effect. The study found that digital economy significantly promoted urban green development, and this promoting effect was more obvious in eastern cities, smart city pilot cities and cities with strong intellectual property protection. Further research shows that digital economy can promote urban green development by promoting the servitization of economic structure, stimulating green technology innovation and enhancing public environmental concern. With the extensive construction of the current digital infrastructure, social electricity consumption and carbon emissions continue to increase, and the impact of digital economy on urban green development has a non-linear feature of diminishing marginal effect. The research conclusions of this paper not only actively promote cities to embrace the new paradigm of green development, but also provide a useful reference for the construction of an intensive and low-carbon modern infrastructure system and the realization of digital green coordinated development.
