摘要
产业关联网络的演变是产业经济研究的前沿问题。以北京市为例,利用该市12个年度的投入产出表构造产业关联网络模型,展示产业关联网络的演变格局,进而计算和比较产业关联网络模型拓扑特征的变化。通过计算与比较发现:产业关联网络的整体布局演变呈现稀疏化特征,网络的平均度和平均路径长度呈现"W"形变化,聚类系数演变显示出"M"形变化过程。进一步的机制分析发现,地区经济总量水平和地区专业化程度负向影响网络中节点连接强度,经济发展方式的转型升级对产业关联网络节点距离产生负向影响。地区经济外向型水平提升使得北京产业关联网络中的环向连接数量降低,导致网络连接的稀疏化问题。针对以上结论,最后给出有关产业经济发展的政策建议。
The evolution of industrial relations network is the frontier of industried economics research. This paper constructs Beijing industrial relations network models using 12 years Beijing Input - Output table, shows the evolution of Beijing industrial relations network, calculates and compares the change in the topologi-cal characteristics of network. The paper points that the evolution of Beijing industrial relations network layout is a sparsification process, the change of the networks average degree and the average path length exhibits a “W” shape process, the change of clustering coefficient of exhibits an “M” type process. Further analysis of the mechanism indicates that, the Beijing total economy and industry specialization negatively influences the average degree, the changes to the upgrade of economic development negatively affects the average path length, the degree of export - oriented of economy positively influences clustering coefficient. With these find-ings, the paper concludes with some policy suggestions for Beijing industrial economy development.
