THE EVOLUTION LAW OF THE FORM OF URBANIZATION RESPONSE TO REGIONAL INDUSTRIAL STRUCTURE EVOLUTION

Joseph Stiglitz,an American economist who received Nobel Economics Prize in 2001,points out that urbanization will be first challenge for China in 21st century,he said,China's urbanization will be engine of regional economic growth,and will produce most important economic interests. Judging from development trend,the massive urbanization in China will last 20-30 years.Urbanization will become an important factor which influences future direction of China's economic development,social progress and sustainable development of resources and environment.Meanwhile,optimization and upgrading of regional industrial structure and orderly promotion of urbanization are important choices during new period of country's economy and social development strategy.The paper introduces concept of the form of urbanization response to regional industrial structure evolution.This concept refers to regional space performance and solid state which is produced in process of interaction between urbanization and changes of industrial structure,and it is concrete manifestation of interaction between region economic units and functional organization on region space.It is unity of urbanization and evolution of industrial structure,and it has both economic and spatial attributes.Based on this,a theoretical model of form of urbanization response to industrial structure evolution is constructed from two layers which are a single inner city and urban agglomerations,and general evolution law of form of urbanization response to regional industrial structure evolution is revealed.The author concludes that cities are developed gradually by what is evolved from form of a single inner city to spatial form of urban agglomerations,from metropolitan areas to megalopolis,regional groups.With support of system of contemporary rapid transit,cities(urban agglomerations) tend towards region swiftly,the interaction and spatial connection between cities and region are provoked,the region space which is city-centered grows gradually,and finally functions of region space evolve into integration.This paper takes Changchun as example,and it confirms general evolution law of form of urbanization response to regional industrial structure evolution.
