Study on the Evolution of Industrial Network Structure Characteristics in Xinjiang Based on Social Network Analysis Method

产业结构的演变对地区经济发展具有重要意义。本研究综合运用社会网络分析法(SNA)，通过合并相似的产业部门，从网络密度、拓扑结构、中心性和凝聚子群等角度来考察新疆产业网络结构的网络属性及其演变。研究表明：1) 新疆产业网络具有较短的路径长度和较高的聚类系数，各部门投入产出频繁，呈现出“小世界”的网络特性；2) 新疆产业发展呈现出阶段性的特征，近年来新疆产业结构逐步向第三产业偏移，经济服务化凸显；3) 二三产业的中心性均较大，没有支配性产业的出现，各类产业间联系增强；4) 新疆产业网络派系总体变化不大，但派系内部产业部门持续变迁，主导派系产业部门逐年增多。The evolution of industrial structure is of great significance to regional economic development. By comprehensively applying social network analysis (SNA), the network attributes of Xinjiang’s industrial network structure and its evolution are examined from the perspectives of network density, topology, centrality and cohesive subgroups by merging similar industrial sectors. The study shows that: 1) Xinjiang’s industrial network has a short path length and a high clustering coefficient, with frequent inputs and outputs in each sector, showing the network characteristics of “small world”; 2) Xinjiang’s industrial development shows stage-by-stage characteristics, and in recent years, Xinjiang’s industrial structure has gradually shifted to the tertiary industry, and the service-oriented economy is highlighted; 3) The centrality of the secondary and tertiary industries is large, and there is no dominant industry, the industrial structure shows a diversified development pattern, and the links between various types of industries have been strengthened; 4) There is little overall change in the industrial network factions in Xinjiang, but the industrial sectors within the factions have continued to change, and the dominant factions have increased in the number of industrial sectors year by year.
