长江经济带产业联动网络的结构特征及其解释

Structural Characteristics and Explanation of Industrial Linkage Network in the Yangtze River Economic Belt

本文利用复杂网络分析法构建了长江经济带产业联动网络,分析显示区际产业联动紧密度明显低于区域内,并且长江经济带下游地区的产业是上游与中游地区产业联动的枢纽。基于这一产业联动现实,实证研究发现区域经济发展差异会促进区际产业联动,而区域分割与地方保护会阻碍区际产业联动,公路与内河航运基础设施对区际产业联动具有明显促进作用。长江经济带产业联动受区域分割影响较大,可通过实施区域联动发展政策,以削弱区域分割对长江经济带产业联动的影响。

In this article, the industrial linkage network of the Yangtze River Economic Belt is constructed by using the complex network analysis, which shows that the inter-regional industrial linkage degree is obviously lower than that of the region, and the industry in the downstream area of the Yangtze River Economic Belt is the hub of the industrial linkage between the upstream and midstream areas. On the basis of the reality of industrial linkage, empirical research shows that regional economic development differences will promote inter-regional industrial linkage, while regional division and local protection will hinder inter-regional industrial linkage. Besides, highway and inland waterway transportation infrastructure will significantly promote inter-regional industrial linkage. Industrial linkage in the Yangtze River Economic Belt is greatly influenced by regional division, and the influence of regional division on industrial linkage in the Yangtze River Economic Belt can be weakened via the implementation of the policy of regional linkage development.
