基于投入产出关联的区域产业部门角色演化研究——京津冀与东北地区的比较分析

文章利用2002年和2007年投入产出表,运用社会网络分析法对比分析了京津冀和东北地区的产业部门角色演化。结果表明:(1)京津冀产业发展越来越依赖于少数几个资源输出部门,东北地区提供资源的部门变化较小,而终端产业部门越来越多。对东北地区而言,高端装备制造业和科技服务业的关联作用有待增强。(2)京津冀和东北地区产业关联网络的分块趋势越来越明显。相比而言,东北地区逐步形成石油开采和加工业、高端装备制造业子群和金属机械制造业子群,但子群间的联系较弱,尤其是现代服务业与其他产业子群间的联系有待增强。

The Evolution of Industrial Role in the Input and Output Related Regions-A Comparative Analysis of Northeast and Beijing-Tianjin-Hebei

By employing 2002 and 2007 input-output table ,the article analyzes the evolution of industrial role in the transition period of Northeast China and Beijing-Tianjin-Hebei regions with social network analysis .The results show that ：（1）Beijing-Tianjin-Hebei region is increasingly dependent on only a few resource provider sectors ,w hile there are only small changes of resource providers in Northeast region ,but there is an increase of receiver sectors gradually .Meanwhile ,we show that the role of high-end equipment manufacturing sector and science technology service sectors should be enhanced .（2）The industrial network of Northeast and Beijing-Tianjin-Hebei area of China is classified into eight blocks .In Northeast region ,the subgroups of petroleum mining and processing sector ,high-end equipment manufacturing sector and metal machinery manufacturing sector are shaped gradually .However ,the linkages among different subgroups are weak .Particularly ,the re-lationships between the modern service sector and other sectors need to be improved .
