生产性服务业FDI对制造业效率影响研究——基于信息基础建设的调节效应

随着产业信息化的发展，信息基础建设对生产性服务业外商直接投资（FDI）和制造业效率之间的关系产生的影响越发显著。因此，揭示信息基础建设在生产性服务业FDI与制造业效率影响关系中发挥的作用具有重要的研究意义。采用2011—2020年中国省级面板数据为研究对象构建调节效应模型，在分析生产性服务业FDI对制造业效率影响的基础上，探讨信息基础建设在生产性服务业FDI与制造业效率影响关系中发挥的作用。结果表明：就全国而言，信息基础建设水平越高，生产性服务业FDI对制造业效率的促进作用越强；进一步考虑到区域异质性后发现，东部地区信息基础建设存在显著的正向调节效应，而西部地区信息基础建设的调节效应并不明显。

Research on the Effect of Producer Service FDI on Manufacturing Efficiency: Moderating effects based on information infrastructure construction

With the development of industrial informatization, the impact of information infrastructure on the relationship between productive service industry FDI and manufacturing efficiency has become more and more significant. Therefore, it is of great research significance to reveal the role of information infrastructure in the relationship between productive service industry FDI and the impact of manufacturing efficiency. The provincial panel data of China from 2011 to 2020 is used as the research object, themoderating effect model is constructed , and the role of information infrastructure in the relationship between productive service industry FDI and manufacturing efficiency is discussed based on the analysis of the impact of productive service industry FDI on manufacturing efficiency.The results show that: on the whole, the higher the level of information infrastructure construction, the stronger the promoting effect of productive service industry FDI on manufacturing efficiency. After regional heterogeneity, it is found that the information infrastructure construction in eastern has a significant positive moderating effect, while the moderating effect of information infrastructure construction in the western region is not obvious.
