Abstract—This paper collected the data of listed companies and its largest shareholders in Shanghai Stock Exchange and Shenzhen Stock Exchange 300 Index from 2007 to 2013. The listed companies are divided by their locations at provincial level. In this paper the regional investment network is identified by the rationale and specification content, and analyzed the structure feature of China’s regional investment network and its evolution based on the complex network theory. The results of our study indicate that China's regional investment network function is gradually improving, and the network connection is complete. Geographical adjacent provinces have more contact and easy to form subgroup after competition and recombination. Contact densities keep increasing both in subgroup and inter subgroup, but provinces contact in subgroup is more than inter subgroup. The polarization effect of regional spatial pattern is gradually weakened, the contact density decreases in the core area, the contact density of edge area inside, edge area and core area is gradually increasing, so the regional investment is developing coordinated and balanced.
Index Terms—Regional investment, evolution, complex network, topological structure.
