Research On Network Structure Characteristics Of Global Industrial Chain

With the economic globalization and the integration of production,and the links between different industries are becoming stronger and stronger,thus gradually forming a global industrial chain between different industries and within each link of product production.Based on this,an in-depth study and analysis of the characteristics of the global industrial chain network structure will help promote the modernization process of China’s industrial chain and gradually enhance China’s participation in the global value chain.At present,the state proposes to speed up the exploration and construction of a new pattern of domestic and international double-cycle industrial development,and actively create international cooperation and competitive advantages.Therefore,China’s readjustment of the industrial chain needs to be placed under the new development pattern,combining with the structural characteristics of the global industrial chain network,to find a path suitable for China’s current industrial development situation,and to enhance the integrity and security of the industrial chain.According to the input-output table data of the World Input-Output Database(WIOD)in2000,2005,2010 and 2014,this paper uses the social network analysis method to construct the global industry overall network,and analyzes the network density overall network characteristics and the network characteristics of individual industries with degree of output,degree of entry and intermediate centrality.On this basis,block model technology is used to cluster global industries,and global industrial chains of each year are obtained.By investigating the characteristics of China,the United States,Germany and Japan’s typical countries participating in the global industrial chain,and analyzing the dynamic changes of China’s status in participating in the global industrial chain,the policy enlightenment of enhancing the security competitiveness of China’s industrial chain and accelerating the modernization process of the industrial chain is obtained.According to the empirical results,the following conclusions are drawn:(1)Since 2000,the global production network has been very close,and the scale of the whole network has become larger and larger.There are direct or indirect relationships between different countries and different industrial sectors.(2)From 2000 to 2014,the global industrial chain structure changed from simplification to complexity and multi-level,the upstream and downstream departments remained stable and showed an increasing trend,the development of intermediate goods hub departments became more and more complete,and the industries of one country to many countries promoted the formation of transnational long industrial chains,realizing the smooth effect and leading effect of international circulation to promote domestic circulation.(3)The participation of China’s basic industries in global production has gradually deepened,and most of them are in the downstream position of the industrial chain;High-end technology products are in great demand in the international market,and the impact of China as an intermediate hub on the global economy can not be ignored.
