区域产业集群发展关联网络的建模与实证分析——以汽车行业和石化行业为例

本文首先根据投入产出直接消耗系数表,结合复杂网络理论的建模思想构建了一类有向加权网络——区域产业结构网络,然后运用2007年全国投入产出数据研究了该网络的一系列特征值。在研究网络的路径问题时,考虑到网络边权是一种相似权,进而转向研究网络的最长路径及其蕴含的产业经济意义。以此为基础,论文又构建了产业间最强关联网络和产业集群发展关联网络,一方面梳理出区域产业规划过程中的关键产业部门,另一方面通过与发达国家和地区进行比较,识别出产业集群化过程中存在的问题。最后选取了汽车行业和石化行业进行了产业集群发展可行性方面的实证分析。

Modeling and Analysis of Industrial Cluster Development Networks

This paper analyzed the theory of complex networks and then made an industrial structure model,which are on the basis of input-output theory.Furthermore,topology of the industrial networks was researched by degree distribution,strength distribution and path length.In view of similarity weights of edges,the longest path and its economic implications were put on primary study,according to which the industrial strongest relevant networks and industrial cluster development networks were built up.On the one hand,through searching this kind of networks,important sectors can be recognized in the process of doing regional plans,on the other hand,problems from clustering can be discovered in contrast with developed countries.Finally,automobile industry and petrochemistry were chosen to analyze the model’s feasibility.
