数字经济与产业链供应链安全:基于智慧城市试点的准自然实验
Digital Economy and Security of Industrial Chain and Supply Chain:A Quasi-natural Experiment Based on Pilot Smart City
摘要
Abstract
The security of industrial chain and supply chain is a core component in promoting high-quality industrial devel-opment,ensuring the stable operation of the real economy,and building a new development pattern.Digital technology,as an emerging factor of production,has injected new impetus to enhance the security of industrial chain and supply chain.Based on panel data of 280 prefecture-level and above cities in China from 2000 to 2020,this paper takes pilot smart city as the exogenous impact variable of digital economy,and systematically analyzes the impact of pilot smart city on the security level of industrial chain and supply chain and their mechanisms of action.The research results are shown as follows:Pilot smart city significantly im-proves the security level of regional industrial chain and supply chain,and this conclusion is still valid in a number of robustness tests.Further mechanism analysis reveals that pilot smart city improves industrial chain and supply chain security level primarily by driving industrial structure upgrading and improving total factor productivity.Moreover,the positive impact of pilot smart city exhibits significant spatial heterogeneity,with the central and western regions and non-Yangtze River Economic Belt cities signifi-cantly benefiting more than the eastern regions and cities within the Yangtze River Economic Belt.关键词
