Spatio-temporal characteristics of foreign monopoly degree in the upstream of Chinese enterprises'supply chain and its innovation effect
Previous studies have focused on the degree of foreign monopoly in the upstream of the supply chain to carry out empirical econometric studies from the macro perspective,but have not paid attention to the typical factual characteristics of its spatio-temporal evolution under the perspective of economic geography and its impact on micro enterprise innovation.In this paper,with the data of A-share listed manufacturing enterprises from 2007 to 2022,we interpret the spatio-temporal dynamic differentiation characteristics of the degree of foreign monopoly in the upstream of the supply chain,and examine the relationship between it and enterprise innovation.The study finds that:(1)In the temporal dimension,the degree of foreign monopoly in the upstream of the supply chain of Chinese manufacturing enterprises shows an overall fluctuating downward trend.In terms of sub-industry,there are obvious differences in the degree of monopoly in various industries in China,and the lack of resources and technology gap have become major influencing factors for the higher degree of monopoly in specific industries,reflecting the fact that resource and technology endowment is an important factor affecting the development of Chinese manufacturing industry.(2)In the spatial dimension,the degree of monopoly in the eastern region is higher than that in the central and western regions,but the degree of monopoly in the central and western regions is gradually increasing,and the centre of gravity of monopoly shows the geographical migration characteristic of"southeast→northeast→southwest".(3)The influence of the degree of foreign monopoly in the upstream of the supply chain on enterprise innovation shows an asymmetric U-curve,and the influence of the degree of foreign monopoly in the upstream of the supply chain on the innovation of enterprises in the non-state-owned sector,the eastern region,and the poor financial background is more sensitive.
