The Study Of Industry Clusters During The Development Of Regional Economy

With China's entry to WTO, economic development is confronting both opportunity and challenge. In this process, the regulation and development of regional economy that is part of macro-economy is playing a significant role in influencing macro-economic development. Presently, however, regional economic development has to deal with the unequilibrium of interregional economic development and the increasing duplication of interregional industrial structures. Sharpened unequilibrium and duplication will inevitably waste more resources and decrease the development rate of national economy.With regard to industries in regional economic development, a cluster of industry in the process of regional economic development is formally studied on the basis of theoretic research and positive analysis. In the theoretic research, considering characteristics of regional economic research, quantitatively and qualitatively, the industrial concentration theory is formulated for the theoretic base of this research with the help of regional developmental theory and industrial economics. In addition, the methodological base of this research is also attained by the formulation of two models: the model of individual industry in the clusters to quantitative economics of national economy, and the model of total clusters of industry to system economics of national economy.In the positive analysis, on the basis of real situation of Jiangsu's economic development and in the use of former theory and models, it is pointed out that Jiangsu's regional economic distance from 1978 to 2001 is not converged mainly due to the increasingly widened economic distance in the northern, central and southern areas of Jiangsu province, especially for the reason that proper and suitable clusters of industry have not been discovered in the northern area. Considering Jiangsu, in the clusters of industry like transportation, finance, real estate and automobiles, real estate and automobiles are the motivation of regional macro-economic development while transportation and finance serve as the base. As to the motivation, real estate is more active than automobiles; transportation plays as an obvious basic role; finance vaguely supports automobiles but is important to the development of real estate. In conclusion, regarding the positive result, corresponding suggestion is proposed for Jiangsu's regional economic development.
