数字经济赋能现代流通体系建设的理论机制与实证检验——来自287个地级市的证据

Theoretical Mechanism and Empirical Verification of Digital Economy Empowering the Construction of Modern Circulation System--Evidence from 287 prefecture level cities

在加快构建新发展格局的当下,如何借力数字经济推动现代流通体系高标准建设,更好服务于国内大循环,成为新时期亟待探索的重要议题。本文采用2004-2021年287个城市数据,探究了数字经济对现代流通体系建设的直接与间接赋能效应。实证结果表明,数字经济能够显著提升现代流通体系建设水平,这一积极作用主要通过促进降本增效、激发包容创新、引导职能强化、加速质量提升等内在逻辑实现。数字经济对现代流通体系建设的影响存在异质性条件约束,具体而言,中部地区的赋能效应最强,东部和西部相对较弱,东北部最弱;同时,非中心城市的赋能效应强于中心城市。数字经济能基于营造创新发展空间、激发流通创业活力、强化金融支持力度等机制赋能现代流通体系建设。因此,须加大数字基础设施投资力度,推动数字技术与流通体系深度融合,因地制宜推进数字经济赋能现代流通体系,努力营造良好赋能环境。

In the context of accelerating the formation of a new development pattern,leveraging the digital economy to enhance the construction of a high-standard modern circulation system and better support the domestic economic cycle has become a key issue for exploration in the current era.This paper uses data from 287 cities between 2004 and 2021 to investigate both the direct and indirect empowering effects of the digital economy on the development of the modern circulation system.The empirical results indicate that the digital economy significantly enhances the level of modern circulation system construction.This positive impact is primarily driven by internal mechanisms,including cost reduction and efficiency improvements,the stimulation of inclusive innovation,the strengthening of functional roles,and the acceleration of quality improvements.The influence of the digital economy on modern circulation system development is subject to heterogeneous conditions.Specifically,the enabling effect is strongest in the central region,relatively weaker in the eastern and western regions,and weakest in the northeastern region.Additionally,non-core cities experience a stronger enabling effect than core cities.The digital economy facilitates the construction of modern circulation systems through mechanisms such as creating innovative development spaces,stimulating entrepreneurial dynamism in the circulation industry,and enhancing financial support.Consequently,there is a need to increase investment in digital infrastructure,promote the deep integration of digital technology with the circulation system,tailor efforts to local conditions,and foster a favorable enabling environment for the digital economy to empower the modern circulation system.
