中国先进制造业与生产性服务业关联网络结构特征

Characteristics of the Network Structure of China’s Advanced Manufacturing Industry and Producer Services

基于最新2020年中国153部门投入产出表,以生产性服务业部门为供给侧,以先进制造业部门为需求侧,构建两业关联二模网络,并分为供给网络和需求网络综合分析两业网络的结构特征。产业网络分析显示:供给网络和需求网络在不同视角下形态各异且存在核心与孤立节点,需求网络结构相比于供给网络更加稀疏;通过中心性分析对产业节点地位做了进一步的量化分析,与可视化结果基本一致;供给网络和需求网络的核心边缘结构不同,且供给网络比需求网络的拟合效果和分块效果更好;二模网络密度显示,联动性的密度主动性低于被动性,个体性的主被动密度在不同部门表现各异。

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.
