提出了一类基于异质性的产业群交易网络模型,采用柯布-道格拉斯函数对网络中群异质性进行了定量刻画和分析,同时给出了产业群网络的结构参数的定义。通过理论分析和仿真实验得出:群间成本与所占共享资源比重呈反比;该群网络是一个非均匀网络,其集中度与群聚集性都非常低。最后,通过实证分析得出,北京市产业关联网络与提出的产业群网络是相符的,且第三产业与其他产业间的异质性较强,第三产业的发展促进了第一、二产业的进步。
An industrial clusters trading network model is built based on the heterogeneity of clusters. The degree of clusters heterogeneity can be quantitatively described and analyzed by the Cobb-Douglas production function. Meanwhile, the definitions of structure parameters of clusters network are given. Theoretical analysis and numerical simulation show that the costs between different clusters are inversely proportional to the proportion of shared resources. The cluster network model is a heterogeneous network which the centrality and the clustering are very low.Finally, empirical analysis obtains that industrial relationship network of Beijing is consistent with that network we proposed. The heterogeneity between the third industry and other industries is stronger. So, we can say that the development of the third industry promote the progress of the first and the second industry.
