基于社会网络视角的中国产业结构变迁实证研究

An Empirical Study on China’s Industrial Structure Change from the Perspective of the Social Network

根据国家统计局公布的中国7个年份的投入产出表,采用社会网络分析法,绘制了7个年份的产业结构网络拓扑图,从网络密度、中心势、中心度、凝聚子群等角度分析了2002年以来中国产业结构网络的特征和变化,并对中国产业结构变迁进行了实证研究。通过结果分析可知,中国的产业结构表现出多样化的特点,产业结构具有阶段性变化的特点,产业部门之间的联系呈波动性变化,各产业部门在产业结构中的地位是不平等的,但是产业部门之间的地位差距趋于减小,中国现在处于工业化的后期,已经开始步入后工业化时代,其中,第二产业的重要性下降,第三产业开始崛起,第三产业的重要性越来越突出,其影响力也逐渐增大,产业凝聚子群的频繁变动将会持续,甚至更加剧烈的情况会出现。

According to the seven years input-output table of the National Bureau of Statistics,the social network analysis to draw the seven years of industrial structure network topology was used.From the network density,centralization,centrality,and cohesive subgroups,the characteristics of China’s industrial structure network since 2002 was analyzed,and the empirical study on China’s industrial structure change was conducted.Through the results analysis,China’s industrial structure has diversification and the characteristics,the link between the industry sector has volatility,the industry sector status in the industrial structure is unequal,but the status of the gap between the industry sector tends to decrease.China is now in the late stage of industrialization,has begun into the post-industrial era.The importance of the secondary industry has declined.The third industry began to rise,the importance of the third industry is more and more prominent,and its influence is gradually increasing.industry cohesive subgroups of frequent changes will continue,Even more dramatic things can happen.
