摘要
在数字经济快速发展及国内价值链面临"断链""卡链"风险的双重背景下,数字技术如何赋能中国价值链稳定性值得探讨.文章在构建嵌入式投入产出表的基础上分别从生产要素投入、增加值波动视角构建指标体系,测算省份—行业层面的数字技术、价值链稳定性水平,并实证检验了数字技术对价值链稳定性的影响及机制.研究发现:数字技术可显著赋能价值链稳定性,主要通过提升生产效率、中间品供应多元化两条途径实现;中西部省份数字技术更能提升价值链稳定性,在制造业领域数字技术更能促进价值链稳定性;投入省外的数字技术及来自服务业的数字技术对价值链稳定性的提升作用更强.研究结论对于统筹经济发展与安全,加快构建新发展格局,推动经济高质量稳步发展具有重要的现实意义.
Abstract
Against the backdrop of the rapid development of the digital economy and the risk of"broken chain"and"stuck chain"in the domestic value chain,this paper delves into how digital technology empowers the stability of China's value chain.Based on China's multi-region input-output table and the world input-output table,this paper constructs an embedded world input-output table covering 21 industries of 31 provinces in China and 62 countries or regions in the world,and on this basis,it constructs an index system from the perspectives of production factor input and value-added fluctuations to measure digital technology and value chain stability at the level of province-industry.This paper also theoretically analyzes and empirically tests the impact of digital technology on value chain stability,expanding to examine the heterogeneity of the impact of digital technology on value chain stability in different factor source regions,different factor source industries,and different factor source regions-industries.It is found that:First,digital technology significantly empowers value chain stability mainly through two ways:enhancing production efficiency and diversifying the supply of intermediate goods.Second,digital technology in central and western provinces and southern provinces better enhances value chain stability,and digital technology in the manufacturing sector better promotes value chain stability.Third,digital technology from outside the province and from the service industry has a stronger role in enhancing value chain stability.Policy implications are that:First,fully explore the development potential of digital technology,vigorously develop the digital economy,and give full play to the positive role of digital technology in maintaining value chain stability.Second,actively improve production efficiency and diversify the supply of intermediate goods to promote value chain stability.Third,strengthen the cross-regional flow of digital production factors,build a unified domestic market,and improve the efficiency of resource allocation.Fourth,encourage the upgrading of manufacturing services to maintain value chain stability.This paper is of great practical significance for integrating economic development and security,accelerating the construction of a new development pattern,and promoting high-quality and steady economic development.
