The evolution and influencing factors of global semiconductor trade network
Amidst the accelerated restructuring of the global industrial chain,accurately grasping the evolutionary trends in the organizational structure of global semiconductor trade networks across various stages and their influencing factors holds significant importance in interpreting a novel world order from the perspective of core high-tech industries.This paper constructs a theoretical framework for the evolution of the global semiconductor trade network from an industrial chain perspective.Semiconductor trade data were from UN Comtrade Database.Complex network analysis,spatial analysis,and negative binomial regression methods are employed to reveal the evolution patterns of the trade spatial layout,trade network topology,and organizational structure of the global semiconductor industry from 2001 to 2022,along with the driving factors.The conclusions of this research are as follows:(1)The trade network for manufacturing equipment has consistently been dominated by the US,Japan,and some Western European countries,while the dominance for manufacturing materials and finished devices continues to concentrate towards East Asia.The trade network has become increasingly interconnected,exhibiting evident characteristics of power-law distribution and a small-world phenomenon.(2)The organizational structure of nodes within the global semiconductor trade network maintains a stable hierarchical system of"core-periphery",with node types contained by dominant and marginal types.Evolution of network relationships shows distinct features of Northern Hemisphere division and Southern Hemisphere integration.(3)Proximity in language and favorable geopolitical economic relations play a facilitating role in the development of the semiconductor trade network,while the positive impact of geographical proximity diminishes and the negative effect of economic proximity strengthens.The economic development level of a country,its degree of openness to foreign markets,and technological advancement all exert varying degrees of influence.However,the impact of social governance level is comparatively minor.
