A Empirical Study On Staged Growth Of Industrial Economy Marked As The Leapfrog Spatial Expansion

As the driver of modern civilization and progress, Industrial economy is also part of urban economy nowadays. The development of industry promotes the upgrading of urban structure and the way of spatial expansion. This article is designed to study the correlation between industrial economy and urban spatial expansion, so that the urban spatial developing orientation and structure can be under control.Based on economics and urban planning theories, this paper studies several cases of urban development, especially about Wuhan with tools like econometric model analysis, CAD, GIS etc. to realize the mechanism that staged growth of industrial economy impels the leapfrog spatial expansion. In the end of paper, the urban special management of Wuhan is proposed on industrial development.There are five parts in this paper:Part1:A preliminary study of principles and theories of western economics, geonomics, and urban planning etc.Part2:According to the research, industry may modify jobs and population distribution as well as urban basic industry and economic category, may create a large number of employment opportunities as well as maintain social stability, improve technical progress, promote comprehensive ability. Industry economy acts on population distribution, function aggregation, facility layout, and eco-structure by means of land demand, scale aggregation, service facility, and infrastructure etc. to lead the development mode of space and land use layouts.Part3:A lot of studies have shown that for the mutual promotion of increase input and scientific efficiency, the industrial economy appears grow like ascendant helix, while the requirements of land and population migration, a mixed effects of urban construction inputs, infrastructure layouts, national policies, and urban-rural planning lead to the urban space sprawl like leapfrog. Industry economy phased growth has the same pace with the leapfrog-urban-sprawl. In this paper, this could be fully proved by the case of Wuhan city. Part4:According to the Chenery’s Model and Kuznets’ Model, Wuhan city is being in the later-stage of industrialization. Based on this view, and SWOT analysis, this paper divides the development stage of Wuhan city into two parts. On the first stage, in2030, Wuhan will mainly develop six new towns in suburban area based on industry development. On the second stage, in2050, Wuhan will form the mutual structure of central city and satellite towns. According the industry chain, there are three presetting urban sprawling types"2+2","3+6+3","3+4+3" in this article.Part5:It is suggested that China should insist development of industry in the global deindustrialization atmosphere. China should lead more inputs to industry and respect the discipline of industry development. Meanwhile China should form spatial structure on the basis of demand of industry economy, construct and govern cities on the basis of industry economy discipline, and guarantee the industry land and service facilities on the basis of the characters of industry economy growth.
