The Study Of Regional Specialization,Geographic Concentration And Regional Integration

Along with the changes of urban orientation of Beijing and Tianjin induced by the central government, and the advent of large opportunities because of the approach of Olympic Games, the economy developmet of the region of Beijing-Tianjin-Hebei has become a hotspot in our country's regional economics research and a nodus in regional cooperation at present. In view of these, this paper selects the region of Beijing-Tianjin-Hebei to do some empirical research on regional specialization, geographic concentration and regional integration.Theoretical investigaton about specialization and geographic concentration rooted in the theories of trade and location. The former includes classical trade theory and Neo-trade theory, but the latter is the new economic geography mostly. Using the new economic geography as an analytic frame, the paper studies regional integraion in the facet of sepcialization and industrial concentration, then search out the motivity and resistance in the course of regional development and cooperation.Firstly, in the empirical research of regional specialization, It analyze the evolvement of the division of labour in the region of Beijing-Tianjin-Hebei according to the calculation results of the intra-region specialization index and the local specialization index. I find that the intra-region specialization index between Beijing and Hebei is the most, but this index between Beijing and Tianjin is the least. I discover the leading indusries in each region according to the calculation results of the local specialization index, and find that the Beijing and Tianjin have a similar industry structure. Secondly, I analyze the industrial geography concentration in the region of Beijing-Tianjin-Hebei and calculate the Ellision-Glaeser Index. We find that the Ellision-Glaeser Index of 14 out of the 20 manufacturing industries in question ascended tremendously, but only 5 industries'index descended during the period of 1993-2004. Thirdly, by using Johanson Cointegration test and Granger Causality test, this paper analyzed the course of regional integration in the region of Beijing-Tianjin-Hebei since the reformation and openness in1980s'. The result indicates that on the whole, the course of regional integration in the region of Beijing-Tianjin-Hebei has intensified continuously. These findings can inform the policy-marking decisions to promote industrial development and regional sepcialization and integration in the three regions concerned. The industrial development in the region of Beijing-Tianjin-Hebei should be achieved by developing the division of labour and cooperation . In the end, On the base of market economic law, taking full advantage of cooperation in region and sharing infrastruction, the further regional development could be realized.
