数字经济发展不平衡、劳动要素流动与国内价值链循环

Unbalanced Development of Digital Economy,Labor Mobility and Circulation of National Value Chain

利用中国多省份区域间投入产出表,进行省份间的两两配对,探讨了数字经济发展不平衡对省际国内价值链循环的影响。研究发现:数字经济发展不平衡显著抑制了国内价值链循环。异质性检验表明,数字经济发展不平衡的抑制作用在低经济发展水平省份间更大;相较于制造业和服务业,数字经济发展不平衡对初级产品和资源型产业的抑制效果更强;对南北区域内部以及区域间都具有显著的抑制效应,并且这一效应在北方区域内部更为突出。机制研究表明,数字经济发展不平衡通过市场、创新以及成本机制对国内价值链循环产生抑制效应。最后,省际劳动力流动有助于弱化数字经济发展不平衡对国内价值链循环的抑制作用。研究为加快构建双循环新发展格局以及推动国内统一大市场建设提供了新的理论分析和政策研究思路。

Using the inter-regional input-output table of multi-provinces in China,this paper discusses the impact of unbalanced development of digital economy on the cycle of inter-provincial domestic value chain by pairwise matching of data between provinces.The result shows that imbalance development of digital economy significantly inhibits the circulation of domestic value chains.Heterogeneity test shows that the restraining effect of unbalanced development of digital economy is greater among provinces with low level of economic development.Compared with manufacturing and service industries,the unbalanced development of digital economy has a stronger inhibitory effect on primary products and resource-based industries.And the imbalance of digital economic development has a significant inhibitory effect on the economic development within and between the north and south regions,and this effect is more prominent in the northern region.Mechanism research indicates that the unbalanced development of digital economy suppresses the cycle of domestic value chain through market,innovation and cost mechanism.Finally,the inter-provincial labor mobility helps to weaken the inhibitory effect of the imbalance of digital economic development on the domestic value chain cycle.This study provides new theoretical analysis and policy research ideas for speeding up the construction of a new dual-cycle development pattern and promoting the construction of a unified domestic market.
