【摘要】：选择沪深两市2000~2009年的上市公司的数据,将上市公司按其所在省份进行划分。以某一省的所有上市公司对另一省的所有上市公司的投资来反映这两省之间的相互投资关系。实际数据证实了省间的相互投资网络属于典型的稀疏型无标度网络,网络中存在相对较多的hub节点。通过聚类分析、绘制网络图的方式研究了网络的变化趋势,证明了西部大开发政策和振兴东北老工业基地政策对缩小中国各省之间的贫富差距的成效并不显著。其中,辽宁是振兴东北老工业基地政策最大的受益者。最后,通过计算网络中西部省份、东北三省与其地区间的相互投资总额,证实了西部大开发政策从2005年开始取得了一定的成效,证明了宏观经济政策的效果逐渐显现。
[Abstract]:According to the data of listed companies in Shanghai and Shenzhen stock markets from 2000 to 2009, the listed companies are divided according to their provinces. The investment of all listed companies in one province in all listed companies in another province reflects the mutual investment relationship between the two provinces. The actual data show that the inter-provincial mutual investment network is a typical sparse scale-free network, and there are relatively many hub nodes in the network. Through cluster analysis, the paper studies the changing trend of the network by drawing the network map, and proves that the policy of developing the western region and revitalizing the old industrial base in Northeast China have little effect on narrowing the gap between the rich and the poor among the provinces in China. Among them, Liaoning is revitalized northeast old industrial base policy biggest beneficiary. Finally, by calculating the total amount of mutual investment between the central and western provinces of the network and the three northeastern provinces and their regions, it is proved that the western development policy has achieved certain results since 2005, and that the effect of the macroeconomic policy has gradually appeared.
