数字经济赋能城市群消费升级的机制和路径研究

The Mechanism and Path for Digital Economy to Empower Urban Agglomeration Consumption Upgrading

数字经济已成为我国经济发展的新动能,其对居民消费结构升级产生的影响不可忽视。基于此,以城市群为视角,利用2011~2019年19个城市群224个城市的面板数据,在测度城市群数字经济发展水平的基础上,梳理了数字经济、产业结构升级和居民消费结构升级3者间的关系。运用动态面板和中介效应实证分析城市群数字经济影响居民消费结构升级的传导路径,并进一步将产业结构水平作为门槛变量研究城市群数字经济对居民消费结构升级的作用机理。研究发现:城市群数字经济在直接推动居民消费结构升级的同时,也能通过产业结构升级间接促进居民的消费结构升级。同时,城市群数字经济对居民消费结构升级还具有显著的门槛效应。因此,引导数字经济和产业结构的融合发展,加强“新基建”投入力度,推进数字产业化进程,以促进居民消费结构优化。

The digital economy has become a new driving force in China's economic development,and its impact on the upgrading of residents'consumption structure cannot be ignored.Based on the panel data of 224 cities in 19 urban agglomerations from 201l to 2019,and the development level of digital economy in urban agglomerations,this paper combs the relationship between digital economy,upgrading of industrial structure and upgrading of residents'consumption structure from the perspective of urban agglomeration.Using dynamic panel and intermediary effect,this paper empirically analyzes the transmission path of digital economy affecting the upgrading of residents'consumption structure in urban agglomeration,and further studies the mechanism of digital economy affecting the upgrading of residents'consumption structure in urban agglomeration by taking the level of industrial structure as a threshold variable.The research finds that while the digital economy of urban agglomeration directly promotes the upgrading of residents'consumption structure,it can also indirectly promote the upgrading of residents'consumption structure through the upgrading of industrial structure.At the same time,the digital economy of urban agglomeration also has a significant threshold effect on the upgrading of residents'consumption structure.Therefore,we should guide the integrated development of digital economy and industrial structure,strengthen the investment in"new infrastructure",and promote digital industrialization to optimize the resident consumption structure.
