1 INTRODUCTION Urban agglomeration researches originated from the concern about the city cluster in the developed areas of western countries. The modern researches have been extended to the specific areas. HALL (2001) summa- rized the generality and difference of urban metropoli- tans in Europe, and analyzed the spatial structure of dif- ferent areas. NAUDE and KRUGELL (2003) analyzed the spatial development of urban agglomeration in South Africa, and thought that the size of the p…  相似文献

Along with the development of urban economy, the growth of urban population and the increase of needs of urban society, the suburban ecological and economic system changes constantly and profoundly in its structure and function. Intensifying the research on structural analysis of suburban ecological and economic system is of great significance for grasping light the laws governing the development and evolution of the suburban ecological and economic system and leading this system onto a path of sound circle. By making comprehensive use of the cluster analysis and latent structural analysis the author attempts to explore a new avenue of revealing the structure of suburban ecological and economic system, taking Tianjin suburbs and counties as an example. The results obtained from the above-stated analyses show that it is entirely possible and extremely effective to study the structure and function of suburban ecological and economic system and provide scientific evidence for control of this system by using mathematical methods and statistical analyses.  相似文献

Aircraft industry is very important to the economy and security of a country, and aircraft industry clusters have already existed in the world. Based on Input-Output data and Czamanski’s method, the aircraft industry clusters in China and USA were identified quantitatively in this paper. Furthermore, this article carried out comparison analyses of the identification results. The research finds out: 1) a mature aircraft industry cluster would be generally composed of 7 industrial subgroups, including aircraft industry, metal making and products manufacturing industry, machinery and equipment industry, electronics industry, automobile industry, material industry and others, and electronics industrial subgroup will play a more and more important role in the cluster; 2) in the range of industry-covering, the level of industry-linkage, and the economic performance, there is a tremendously large gap between the aircraft industry cluster of China and that of USA; 3) the spatial evolution of these clusters or centers is highly consistent with the diffusion of a country’s industrialization. Finally, based on those findings, the paper gives some advice on how to improve Czamanski’s method and what China should do to develop its own competitive aircraft industry: 1) China should employ institutional innovation, and turn to be market-oriented; 2) China should abandon the traditional pattern of closed-development, and strengthen the interaction and collaboration between aircraft industry and related industries, especially the electronics industry; 3) China should rectify and perfect its spatial development planning of aircraft industry.  相似文献

Urban agglomeration （UA） compactness means spatial concentration degree of physical entities, such as cities （towns）, industries, resources, funds, traffic and technologies, whose concentration is formed according to specified economic and technologic association in the process of UA formation and development. The UA industrial compactness means the concentration degree of industry and industry clusters with reference to the industrial, technological and economic relations among the cities in the UA in the process of rational industrial division and with the extension of industrial chain. After analyzing the researches on compactness, this paper finds that the relevant measurement coefficient and methods reflecting industrial geographical concentration fail to link industries spatial concentration with urban spatial concentration. Taking 23 UAs as samples and classifying them by development degree, this paper probes into UA compactness and spatial distribution characteristics from the perspective of industry by adopting UA index systems of industry and measurement models. The research finds out： 1） there is obvious positive correlation between UA industrial compactness and UA development degree; 2） the spatial distribution difference of UA industrial compactness is relatively great; and 3） UA industrial compactness shows a gradually decreasing tendency from the eastern part, the middle part to the western part of China. From the research thoughts and approaches, this article suggests that studies on the UA integrated compactness measurement should be enhanced from a multidimensional per- spective involving space, traffic, population density and so on.  相似文献

The second-tier extended metropolises in the Changjiang (Yangtze) River Delta, including Suzhou, Wuxi and Changzhou near Shanghai, are becoming the most active and new innovative industrial agglomerating areas. Manufacturing industries in these second-tier cities have been in rapid growth due to increasing foreign investment. Nevertheless, the economic prospect of these cities is still constrained by a lack of local R&D capacity and production services, which are mainly dependent upon Shanghai. This paper analyses the impact of globalization on the new economic sectors in these cities, the change of industrial structure, the limitation of urban development and the problem of sustainability. Then, the paper analyses the conditions for the high-tech industry and production services in these areas. Also, it applies the industrial organization theory to these cities and examines how these cities can cooperate with each other in terms of horizontal linkages. Finally, the paper gives the future growth prospects in high-tech industry and production services.

As responses to metropolitan suburbanization and rural urbanization,the formation and evolution of urban fringes should be understood against the background of overall economic development and spatial reconstruction of entire metropolises.At the same time,however,endogenous interactions between industrial structure and spatial patterns of non-agricultural activities are also worthy of scholarly attention.Since the 1980s,studies on urban fringes in China have been restricted by the lack of micro-level data.This paper investigates the spatial expansion and structural evolution of the urban fringe by taking the case of Beijing and uses systematic firm-level data in 1996 and 2001 from the National Census of Basic Units.The diversity of distribution patterns across industrial sectors brings about two interrelated results.On the one hand,structural adjustment of non-agricultural industries promotes the expansion and spatial evolution of the urban fringe.On the other hand,the stability and dynamics of industrial structure coexist in the moving urban fringe.This study also reveals that the outward-moving urban fringe is the optimal location for manufacturing,especially heavy manufacturing,as well as traditional producer and consumer services.However,industries with spatial stickiness such as tourism and sports have not moved with the fringe.Most advanced services remain concentrated in the city center.The authors argue that it is essential for understanding and managing urban fringes to take into account spatial evolution and industrial structural adjustment together with their interaction with each other.  相似文献

At present China is facing challenges from economic globalization, ecological economy and knowledge economy in its process of economic development. The following ideas may be heuristic in establishing China’s regional development strategies: 1) In locating industries, the impact of industries on the eco-environment should be fully considered. 2) Industrial restructuring should be focused on the restructuring of products, not on the restructuring of the three traditional industries (primary, secondary and tertiary industries). 3) The establishment of key industries should be focused on large-scale corporations or famous brand products, not on a particular industrial sector. 4) The complementarity and cooperation between the east and the west of China should be on products and markets, not on natural resources. The advantages in natural resources for the west of China can not be over-estimated. The advantages in products and market potentials for the west of China may be explored.  相似文献

As one kind of organizational relation of regional space, in essence, urban system is the spatial reflection of the deep social economic movement.(HERZOG,1991). Since the 1980s, by means of the globalization of economy and high technology and the particular spatial effect, the evolution of urban system has taken on one brand-new landscape different from the traditional one, which also raise new concepts and requirements for urban system planning. Meanwhile, it′s no doubt that active plannin…  相似文献

The Pearl River (Zhujiang) Delta (PRD) has been a focal point in reform era academic circles not only for its dramatic industrial growth but also the simultaneous agricultural development. Unlike most of existing research on the PRD economic development and transformation from the whole region level, this paper explored this question from the perspective of a township using Beijiao in Shunde City as a case study. Unlike the conclusions of existing studies which attribute the regional economic transition to the macro factors, particularly the influence of external investment, this research reveals that at the level of township, the local government, the town-village owned enterprises and the individuals have been playing remarkable roles in local economic transformation. In the early stage since the economic reform, Beijiao township government, replacing the central and provincial governments before, began to manipulate the development of town-village owned enterprises and lead the local economic transformation from agricultural to industrial dominated. As the town-village owned enterprises grew during the later years, they gradually acted as the main dominant player leading the local agricultural and industrial growth. At the same time the individuals in Beijiao were playing more independent role to gain their most profits. While the local government changed to be the real manager of local economies. So the local economic transition was not entirely externally driven. In another word, the “driven from outside” model can not totally explain the economic fact in this specific region.

The seven economic zones are multiple economic zones, with the characteristic of both long-range economic zone and categorical economic zone. They are the transitional regions between the categorical economic zone and the comprehensive economic zone. The phenomena of overlapping are only allowed to appear in categorical economic zones. The influence of Hongkong return back to China should be considered when doing research on economic zones. Hongkong is the center of the southeastern coasts and will become an offshore banking center of the mainland. According to the theory of economic zoning, the division of the whole country into seven economic zones demonstrates the transitional nature clearly. With the further development of the economy, the deeper maturity of the central cities and the stronger connection of the regional economy, the composite economic zones will gradually turn into more integrated comprehensive economic zones.  相似文献

Local governments have long been ardently pursuing the industrial specialization effect (MAR externalities) and industrial diversification effect (Jacobs externalities). Such a pursuit has resulted in severe distortion of resource allocation and negative effect on sustainability of local economic development. Regarding the effect from both MAR and Jacobs externalities on local economic development existing literature records notable disputes. Therefore, for local economic development, one important issue is which externality (MAR or Jacobs) can better bring the effect into play. By studying a panel data of 283 Chinese cities from 2003 to 2012 and applying dynamic plane data GMM method, this paper conducted a regression analysis of the relationship among industrial agglomeration externalities, city size, and regional economic development. The result indicates that with regard to the whole nation, MAR externalities are conducive to regional economy development whereas Jacobs externalities will, to an extent, restrain regional economic development. As regards eastern, middle, and western regions, MAR externalities are conducive only to the economic development of the eastern region; their effects on middle and western regions are insignificant. Moreover, the interaction item between MAR externalities and city size has a significant negative synergistic effect on national economic development and a certain acceleration effect on eastern region as well as a strong negative synergistic effect on the middle region and an insignificant effect on the western region. The interaction item between Jacobs externalities and city size has a positive synergistic effect on only the middle region and has an insignificant synergistic effect on both eastern and western regions. Capital stock and labor input have significant accelerating effects on GDP growth per capita of Chinese cities, whereas material capital and labor input remain primary driving forces for Chinese local economic development. Furthermore, human capital contributes to accelerating urban economic development, whereas government intervention restrains urban economic development.  相似文献

China is a country with a vast marine territory whose area covers one third of the total land territory area. With the exploitation of marine resources and the development of marine economy, marine economic regions have been formed gradually. We shouldn’t ignore them when we divide economic regions throughout the whole nation, especially in our country. In this paper, we’ Il expand division principles, practice and methods of marine comprehensive economic region. Liaoning Province, facing the Yellow Sea and the Bohai sea, is not only a part of Round-the-Bohai Sea Economic Region, but a part of national marine econemic region. Through evaluating marine resources of Liaoning, and analyzing development of marine economy, composition of marine industries and distributional characteristic of marine economy, Liaoning marine region is divided into Bohai Sea marine economic region and Yellow Sea marine economic region based on differences of marine economy. Thereby we go further into the formation of regional marine economic region and distributional mechanism of regional marine economy.
