Evolution of the Global Semiconductor Trade Dependence Networks and Its Risk Relationship Identification:Concurrent Discussion on the Change of China's Status
This paper constructs of trade dependence networks for key commodities in the semiconductor industry,and reveals the spatiotemporal evolution of global semiconductor trade dependence networks.At the same time,it integrates the relations of trade dependence,international competition and geopolitics to construct a dependence risk measurement model,examines the trade dependence risk relationship and its changes,and further discusses the change of China's status in the trade dependence networks of the semiconductor industry.The results show that:1)The average dependence level of the trade dependence network of key commodities in the semiconductor industry is significantly reduced,and the dependence agglomeration characteristics are gradually increasing.2)The trade dependence relationships gradually shift in regional space,showing the characteristics of"rising in the East Asia and falling in the Western Europe and North America",but the core position of North America in the trade dependence network of integrated circuit is stable.3)The global semiconductor trade dependence is primarily at low risk,the risky relationships are mainly concentrated between some small countries and large countries and show an expanding trend.The trade dependence risk index between core economies such as China and the United States remains low,and there is no outstanding trade dependence risk,which is deviated from the risk perception of the West.4)China's status in the trade dependence network of various commodities in the semiconductor industry has been continuously improved,and its power disadvantage status in specific trade dependency relationships has reversed,and its risk dominance has been significantly strengthened,however,there is still a certain gap with the United States'influence in the trade dependence network of integrated circuit.
