International Trade Network Topological Structure and Its Impact on Economic Growth:A Case Study of Semiconductor Trade
Under the background of the development of digital economy,this paper selects semiconduc-tors which are the foundation of digital economy construction as the research object,using the semicon-ductor trade data(HS code is 8541)of the United Nations Commodity Trade Database from 2001 to 2020 to construct a directed weighted semiconductor international trade network based on complex network methods and its topological structure characteristics are analyzed.Through panel regression model,the impact of network topology on global economic growth and its mechanism of action are explored.The results show that the semiconductor international trade network presents the characteristics of a small world network.China and the United States have a high in-degree,closeness centrality and eigenvector centrality,which means that they are all in the center of the trade network.China's centrality status continues to rise,but the United States'centrality declines.The improvement of the individual centrali-ties about semiconductor international trade network significantly promotes economic growth.The more active,central,and influential a country(region)is in the network,the faster its economy grows.The mechanism analysis results show that the central structure of network promotes economic development through technological innovation.In addition,whether a country(or region)is a country(or region)along the Belt and Road and an OECD member has a heterogeneous impact on the relationship between semiconductor trade network centrality and economic growth.This paper offers some policy recom-mendations for China's semiconductor industry and economic growth from the perspective of economic globalization,as well as new research ideas for the study of economic problems based on complex network and econometric theory.
