The Research Of Bohai Rim Industrial Structure Adjustment Based On Industry Association

Industry as the rapid and stable development of the national economy has made important contributions, but with the development of industry, energy consumption and pollution of the water environment is also increasing.As the largest economic region in northern China, Bohai Rim becomes the third of China’s economic growth poles after the Pearl River Delta and Yangtze River Delta which has an extremely important position in China’s economic development. Currently, Bohai Rim is in the later stages of industrialization and industry is still the main force promoting regional economic development. Recently, the other four provinces except capital Beijing have caught large industrial projects. Heavy chemical projects, such as petrochemical, steel,coal, ships, heavy machinery, are widely lie out along the Bohai coast. Industrial structure of Bohai Rim is seriously inclind to heavy industry. In the long run, the way of economic growth with high input, high pollution and high energy consumption is unsustainable doomed to pay huge environmental price. As a direct influence of Bohai environment, the social and economic activities of Bohai Rim will affect Bohai sea environment, which puts Bohai under huge environmental pressure. Therefore, study the industrial structure of Bohai Rim and promote the regional industrial structure rationalization and advancement has practical significance for regional economy rapid development.The contents and conclusions are as follows:(1) Based on MRIO model, the interregional input-output model of Bohai Rim is established and the interregional industrial relationship of Beijing, Tianjin, Hebei, Liaoning and Shandong are also analyzed. Results show that industrial structure of Bohai Rim obtains an obvious characteristic in heavy industrialization and no significant difference in the industrial structure is found between any two regions.(2) On the basis of Leontief’s input-output technology, Input-Output Tables of different region but of the same year are integrated to establish the interregional input-output model of Bohai Rim, providing theoretical foundations for industrial relationship study of Bohai Rim.(3) Interregional input-output model of Bohai Rim as the base, development trend of typical heavy industry of Bohai Rim and their industrial affection on other industrial sectors are analyzed. Study has found out that industries on which the petrochemical industry, steel industry, and equipment manufacturing industry have the significant industrial affection are centralized in heavy industry. It is also found that mutual industrial affections among these typical industries are the most significant, forming the self-circulation within regional heavy industry.(4) Scenario analyses of industrial structure correlation effect of Bohai Rim are carried out from two perspectives:the Leontief inverse matrix and the stage of industrialization, providing basis for the scenario analysis of industrial energy consumption and that of industrial wastewater discharge.(5) Relationships of industrial structure and energy consumption, water environmental pollution have been analyzed, and relevant energy consumption and industrial wastewater discharge in three situations are simulated. Results show that under the baseline scenario,, the extra energy consumption and the extra industrial wastewater discharge required by the industrial affection are the least, while those are relatively greater under accelerated transformation scenario and linear growth scenario.(6) Finally, based on the conclusions above and relevant statistical data and document literature, proposals for industrial structure adjustment are put forward against the existing problems in industrial structure of Bohai Rim...
