Study of regional industrial structure model based on complex networks theory and DEMATEL model

An industrial structure model is built based on complex networks theory and input-output theory. This paper chooses Beijing and Shanghai to make the practice research and analyzes regional industrial structure. The results, which can provide the theory base and reference data for government making relevant policy, show that the leading industries of Beijing and Shanghai both are traditional industries and the status of farming, forestry, animal husbandry and fishery gradually decreased; the rise of scrap and waste industry proof the efforts made by China towards to protecting environment; metal smelting and processing, chemical, transportation and storage are still in a very important position and should be given enough attention. The results could provide theory base and reference data for government making relevant policy.
