Characteristics of the Network Structure of China's Advanced Manufacturing Industry and Producer Services
Based on the latest input-output table of 153 sectors in China in 2020,the two-mode network of the two industries is constructed with the producer service sector as the supply side and the advanced manufacturing sector as the demand side,and the structural characteristics of the two industry networks are comprehensively analyzed by dividing the supply network and the demand network.The analysis of industrial network shows that the supply network and the demand network have different forms and core and isolated nodes from different perspectives,and the structure of the demand network is more sparse than that of the supply network.The status of industrial nodes is quantitatively analyzed through the centrality analysis,which is basically consistent with the visualization results above.The core edge structure of the supply network and the demand network is different,and the fitting effect and block effect of the supply network are better than that of the demand network.The density of the two-mode network shows that the active density of linkage is lower than that of passivity,and the active and passive density of individuals varies in different departments.
