| In the background of regional economic group development, base on new situation of the " the western development strategy","Lanzhou-Baiyin Economic Zone Development Plan" and "Lan-Xi-Ge economic zone plan", which were been gradually put on the agenda of government. Taking Lan-Bai-Xi urban agglomeration construction as the subject, the spatial scope, city function and the cities’level of Lan-Bai-Xi urban agglomeration have been analyzed. The industry evolutions of Lan-Bai-Xi urban agglomeration have been analyzed from three aspects of the spatial distribution of industries, industrial structure and industrial efficiency. In order to provide theoretical support for development of Lan-Bai-Xi urban agglomeration, and finally path optimization was suggested to promote industry evolution of Lan-Bai-Xi urban agglomeration.The structure of the paper is from theory to empirical study, which is divided into8chapters. The contents are as follow:The first chapter is introduction. Firstly, this chapter expounds the importance of industry characteristics of the urban agglomeration from the two aspects of the research background and significance of topics. Secondly, review the domestic and international research results about the urban agglomeration, such as regional industrial structure, the optimization of the industrial structure, industrial agglomeration and so on. And by comparison with the national23urban agglomeration, we have combed the typicality and significance of studying Lan-Bai-Xi urban agglomeration. Finally, this paper on the research methods, research content, research ideas and the innovation and deficiencies are introduced.The second chapter is basic concepts and related theories. Firstly, according to the emphasis of the study, the study has defined some concept, such as West China, city, urban agglomeration, spatial structure, industrial agglomeration, industrial structure optimization, industrial efficiency and other basic concepts involved. Then, discussed the classical theory involved in the research, including the basic theory of industry evolution, regional industrial spatial organization theory, the classical location theory, the modern location theory, the modern location theory and new economic geography theory.The third chapter is characteristic of urban agglomeration. Firstly, by the city gravitation model, Lan-Bai-Xi urban agglomeration space was defined. Secondly, on the basis of urban agglomeration regional characteristics and resource endowment, consider the development of urban agglomeration with the economic and social development positioning of the urban agglomeration were summarized. Finally, the city center, the city grade, traffic accessibility, economic relations and economic ties membership of Lan-Bai-Xi urban agglomeration were determined. The results show that:(1) Lan-Bai-Xi urban agglomeration with Lanzhou as the core, which has the characteristics of economic primacy distribution. The spatial scope of Lan-Bai-Xi urban agglomeration includes:Lanzhou, Baiyin, Xining, Dingxi, Linxia and Haidong.(2) On the basis of urban agglomeration regional characteristics and resource endowment, combining with the development stage of urban agglomeration of economy and society, the whole function of Lan-Bai-Xi urban agglomeration are orientated.(3) Lanzhou is the central city of Lan-Bai-Xi urban agglomeration, Xining and Baiyin are the second level of Lan-Bai-Xi urban agglomeration, Dingxi, Linxia and Haidong should be used as the three center city in the Lan-Bai-Xi urban agglomeration. By comparing with other typical urban agglomeration, analyzed the problems of the development process of Lan-Bai-Xi urban agglomeration, and puts forward the path optimization and upgrading from regional integration perspective.The fourth chapter is factors of industrial agglomeration level and influence of urban agglomeration. This chapter measure industrial aggregation level of urban agglomeration by spatial Gini coefficient and location entropy, results showed that:(1) According to the spatial Gini coefficient, it can be seen that the agglomeration of capital intensive and technology intensive industry is highest among the18industries of Lan-Bai-Xi urban agglomeration, service type of industry shows scattered distribution as the distribution of population the in space.(2) By using the location entropy, we can find that the18industry is more significant in the degree of agglomeration of Lanzhou and Xining, which is also in line with the two city as Lan-Bai-Xi urban agglomeration integrated center city, the18industry is only part of the industry cluster in Dingxi, a higher degree of Baiyin, Linxia and Haidong, which also has the direct relations with the function of economic development level and the local city.(3) Based on the analysis of influence factors, Lan-Bai-Xi urban agglomeration at this stage, the industrial agglomeration degree of Lan-Bai-Xi urban agglomeration are significantly influenced by the market scale and transportation costs, contrarily, the role of effective supply of labor force, economic openness and regional innovation is much smaller, and not significantly affected by the degree of openness and labor supply effect. Based on the above analysis, and finally put forward to promote Lan-Bai-Xi urban agglomeration of industry agglomeration path.The fifth chapter is analysis the characteristics of the industrial space. This chapter is the further deepening of the fourth chapter, using the method of ESDA (Exploratory Spatial Data Analysis) the spatial distribution of three major industries in41counties in Lan-Bai-Xi urban agglomeration were analyzed, results showed that:(1) In the2005-2010years, the global autocorrelation analysis showed that the county industrial city group growth presents a clear spatial autocorrelation, namely the growth effect of similar cities tend to cluster together, but still weak autocorrelation intensity difference and each component effect is obvious.(2) In the2005-2010years, the local spatial autocorrelation analysis further draws the city group area three output value of industry growth in total, shift-share component, the industrial structure deviation component and competitiveness deviation component HH, LL zone is not entirely coincidence, that the three spatial layout and the allocation of resources industry development still has optimized much larger space.The sixth chapter is analysis industrial structure of urban agglomeration. This chapter uses the method of SSM (the shift-share method) to analysis the industrial structure of6citise, the results show:(1) Lan-Bai-Xi urban agglomeration of municipalities (state, region) and overall from2005to2010, GDP into increasing trend, and consistent with the Gansu province and Qinghai province’s overall growth trend.(2) Lan-Bai-Xi urban agglomeration of municipalities (state, region) and the whole first industrial structure deviation component are negative, that group of municipalities (state, city area) and the whole of the industry output growth rate is less than Gansu province and Qinghai Province in the GDP growth rate.(3) Lan-Bai-Xi urban agglomeration of municipalities (state, region) and second overall industrial structure deviation component is positive, indicating that the city cluster and the municipalities (state, the proportion of the second industry area) in the regional economic development have increased characteristics.(4)Lan-Bai-Xi urban agglomeration of municipalities (state, region) and second overall industrial structure deviation contribution rate was more than zero, but the industrial structure of the tertiary industry contribution rate of the deviation is less than, second industrial played a positive role on regional economic development. Lan-Bai-Xi urban agglomeration of municipalities (state, region) and competitiveness overall second industry deviates from the contribution rate of only Xining and Dingxi is more than zero, second industrial competitiveness needs to be enhanced. Lanzhou, Baiyin, Linxia, Haidong and city population was less than zero, which show the enhancement of urban agglomeration of industrial competitiveness is very important. Finally, based on the analysis of industrial efficiency of Lan-Bai-Xi urban agglomeration we can come up with industrial efficiency path of ascension:(1) For first industry development, should form the regional feature advantage.(2) To promote the second industry, to promote the rapid development of industrial economy.(3) Improve the tertiary industry, the formation of reasonable industrial system.The seventh chapter is analysis of industrial efficiency of urban agglomeration. By uses of DEA (Data Envelopment Analysis) to analysis the efficiency of three major industries of6cities in Lan-Bai-Xi urban agglomeration, results showed that:(1) The primary industry efficiency of Xining and Dingxi is relatively high in Lan-Bai-Xi urban agglomeration.(2) Among the Lan-Bai-Xi urban agglomeration, the secondary industry efficiency of Lanzhou and Xining is relatively high.(3) The efficiency of tertiary industry is affected by industrial efficiency of the secondary industry, the tertiary industry industrial efficiency of Lanzhou and Xining is significant high Lan-Bai-Xi urban agglomeration. And then put forward the optimization path.The eighth chapter is conclusions and research prospects. This chapter from the two aspects of theory and empirical summaries the main conclusions of this paper, and the innovation of the paper and should be studied further are discussed. |
