Research On Geographical Concentration And Agglomeration Of Industries In Lanzhou: An Empirical Study Basied On Enterprise Perspective

With the advance of economic globalization and the development of regional integration, regional specialization and industrial concentration, as the expression of industrial structure's optimal allocation among the global or regional scale, become a global economic phenomenon. However, the space forms of these economic activities attract more and more attention by geographers and economists because of its far-reaching impact on urban development.Bai, Fan, Scott and other scholars has done numerous studies on the geographic concentration and agglomeration of industries in China. However, many of these studies are analysis of provincial scale based on national statistical data or the economic census data which was updated once every 5 years. At present, as the difficulty of obtaining micro-enterprises date, the existing research on the spatial distribution of urban manufacturing are mostly about the transformation of industrial land and its influencing factors, drivers and formation mechanism, from the perspective of the distribution and conversion of urban land use types. But such research is rarely conducted based on enterprises'location perspective, and is mainly concentrated in enterprises of specific types, such as foreign-owned enterprises, high-tech enterprises and so on.Based on the data of the whole manufacturing enterprises in Lanzhou in 2008, using town or neighborhood in administrative divisions as the basic space unit, this paper analyze the spatial distribution of manufacturing industry, regional specialization and industrial agglomeration in Lanzhou. Firstly, this paper analyze the spatial distribution of manufacturing industry in Lanzhou from two levels:city territory level and city zone level, and from there aspects:total distribution, industry type distribution, firm size distribution, in order to illustrate the new structure and new law of the manufacturing industry in Western China after reform and opening up; Secondly, based on the Geordie coefficient analysis of double-digit and three-digit manufacturing industries, this paper studies on the geographical agglomeration of industries in Lanzhou among different industry scales and different space scales, and explains the reasons of the formation of diversity between different scales; Thirdly, based on the Geordie coefficient analysis from the town (neighborhood) perspective, this paper measures the degree of manufacturing specialization of every space unit in Lanzhou, in order to make a deeply discussion about the pattern of manufacturing geographical agglomeration of Lanzhou; then, identifies the industry clusters in Lanzhou by the method of location entropy analysis, analyzes their spatial characteristics and firm size structure; Finally, this paper attempts to construe the influence factors of the geographical pattern of manufacturing of Lanzhou.
