摘　　要：已有文献聚焦供应链上游国外垄断程度并从宏观视角开展经济学实证计量研究,但未重视其在经济地理学视角下时空演变的典型事实特征及其对微观企业创新的影响。本文借助2007—2022年A股上市公司制造业企业数据,解读供应链上游国外垄断程度的时空动态分异特征,并分析其与企业创新之间的关系。研究发现:①时间维度上,中国制造业企业供应链上游国外垄断程度整体呈现波动下降的趋势。分行业来看,中国各行业供应链上游国外垄断程度差异明显,资源缺乏与技术差距成为特定行业供应链上游国外垄断程度较高的重要原因,反映了资源和技术禀赋是影响中国制造业发展的核心因素。②空间维度上,东部地区的供应链上游国外垄断程度高于中西部地区,但中西部地区的供应链上游国外垄断程度逐步提高,垄断重心呈现出“东南→东北→西南”的地理迁移特征。③供应链上游国外垄断程度对企业创新的影响呈非对称的U型曲线特征,且供应链上游国外垄断程度对非国有、东部地区和较差金融背景等类型企业创新的影响更为敏感。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.
