【摘要】：在全球经济一体化、网络信息一体化和要素资源共享化的三重背景下,区域内部要素流动的加快,促进了城市群内部城市之间、城市群与群外地区之间联系的加强,也进一步推动了城市群社会经济的发展及其空间组织的演变。而合理有序的空间组织可以促进城市群效率的提高,使区域内部的要素进行合理流动,还是关乎地区竞争力形成和城市群效率提升的重要环节。京津冀城市群、长三角城市群和珠三角城市群是我国城市群中城镇化水平相对较高、经济发展迅速及高新技术及高新产业聚集水平较高的城市群,但是其城市群空间组织与空间效率存在什么样的一种关系,是否还有效率提升的可能已经成为中国三大城市群发展的主要问题。因此,本文立足于京津冀、长三角和珠三角城市群,以发现问题和解决问题为向导,在城市群最优规模理论、空间相互作用理论和中心地理论的基础上,通过分析城市群空间组织对其空间效率的影响,进而提出优化城市群空间组织的政策及建议。本文通过对往年城市群空间组织研究的总结和梳理,发现目前对其空间组织的研究,大多集中在城市群规模分布以及城市群空间结构的演化模式,缺少其与城市群空间效率之间关系的实证分析。将城市群最优规模理论、空间相互作用理论和中心地理论作为文章研究的主要依据,本文认为不同时间段或不同城市群所表现出的空间组织特征不同,其区域的空间效率也各不相同。每个城市群所具有的效率不同主要是由每个城市群的空间组织特征不同,所拥有的资源禀赋不同及空间演化模式不同造成的。城市群空间组织的形成与其空间效率的测算都涉及到了城市群内部各生产要素在整个城市群区域的配置。城市群空间组织的形成是城市群内部要素流动,集聚与整合的过程及外在表现,城市群空间效率则是城市群内要素资源流动的结果。鉴于此,本文以中国三大城市群为研究对象,通过实证分析验证城市群空间组织与城市群空间效率之间的关系。其次,城市群的现状和特征是本文的研究基础,为了全面系统地认识它,本文在空间组织定义的基础上,从城市群的规模、结构和经济联系程度三个方面对城市群空间组织进行研究,研究发现长三角的人口规模总量最大;京津冀的人口密度最大;城市群的人口规模在近20年中表现出上升趋势,人口密度呈现出先下降后上升的趋势;城市群空间结构方面,三个城市群均呈现出圈层式结构特征,其中珠三角的中心度最接近1,空间结构最优,其高位城市没有较强垄断性可以促进周边区域的发展,中小规模的城市也能在高位城市的辐射作用下健康发展。珠三角的经济联系程度值和首位度均比其他两个城市群大,表明珠三角城市群空间相互作用力较强,首位城市的辐射能力较强。接着本文根据城市群空间效率内涵,从人流、物流、信息流等综合角度建立空间效率测算的指标体系,运用数据包络分析对中国三大城市群1995年到2014年的整体空间效率进行测度,探寻了不同城市群空间效率及其演化特征,得出珠三角与京津冀空间效率比长三角高。在城市群空间效率的测算基础上,根据其与城市群空间组织各个指标之间的拟合图提出来本文的假说。最后,将生产函数作为本文实证分析的主要依据,在其基础上构建实证检验模型,采用面板数据固定效应进行回归分析,并根据实证结果得出相关的结论。结论表明:我国三大城市群人口规模、人口密度和空间经济联系不断提高,整体上呈现圈层式空间结构不断加强;城市群人口规模总量与城市群空间效率之间呈倒“U”型关系,城市群人口密度对城市群空间效率有负向影响,中心度和首位度的增大均可以促进城市群空间效率的提升,而且这种对空间效率的提升程度随着城市群人口规模总量的变化而变化,当城市群人口规模总量较小时,城市群中心度和首位度对城市空间效率的影响较明显;当城市群人口规模总量较大,城市群发展逐渐成熟时,中心度与首位度对城市群空间效率的影响逐渐被弱化;城市群内部的经济联系程度与其效率之间存在一种正相关关系。最后文章将城市群空间组织对效率影响的实证分析作为本文的主要依据提出了关于城市群空间组织优化的政策建议。
[Abstract]:Under the three background of global economic integration, the integration of network information and the sharing of factor resources, the acceleration of regional internal elements flow has promoted the strengthening of the links between cities within the urban agglomeration, the urban agglomeration and the outside of the group, and further promoted the development of the social economic development and the evolution of the spatial organization of the urban agglomeration. The spatial organization of order can promote the efficiency of urban agglomeration, and make the elements in the region rational flow. It is also an important link to the formation of regional competitiveness and the efficiency of urban agglomeration. The urban agglomeration with high level of high and new technology and high and new industries has a high level of agglomeration, but there is a relationship between the spatial organization of the urban agglomeration and the efficiency of space. The possibility of improving the efficiency has become the main problem for the development of the three big cities in China. Therefore, this paper is based on the discovery of Beijing Tianjin Hebei, the Yangtze River Delta and the Pearl River Delta city group. On the basis of the theory of optimal scale of urban agglomeration, the theory of space interaction and the theory of central land, the paper analyzes the influence of the spatial organization of urban agglomeration to its spatial efficiency, and then puts forward the policies and suggestions to optimize the spatial organization of urban agglomeration. It is found that the research on its spatial organization is mostly focused on the scale distribution of urban agglomeration and the evolution model of urban agglomeration space structure, and the empirical analysis of the relationship between the urban agglomeration and the spatial efficiency of the urban agglomeration is lacking. The spatial efficiency of the region is different for different time periods or different urban groups, and the efficiency of each city group is different mainly by the different spatial organization characteristics of each city group, the different resource endowments and the different spatial evolution patterns. The formation of the spatial efficiency of the urban agglomeration involves the allocation of the elements of production in the urban agglomeration in the whole urban agglomeration. The formation of the spatial organization of the urban agglomeration is the process and external performance of the flow, agglomeration and integration of the inner elements of the urban agglomeration, and the spatial efficiency of the urban agglomeration is the result of the flow of elements in the urban agglomeration. The relationship between the spatial organization of urban agglomeration and the spatial efficiency of urban agglomeration is verified through empirical analysis. Secondly, the status and characteristics of the urban agglomeration are the basis of this study. In order to fully and systematically understand it, this article is based on the definition of spatial organization, from the scale, structure and economic connection of the urban agglomeration. The total population size of the Yangtze River Delta is the largest in three aspects. The population density of the Yangtze River Delta is the largest; the population density of Beijing Tianjin Hebei is the largest; the population size of the urban agglomeration has shown an upward trend in the last 20 years, and the population density presents the trend of the first descending and then rising; and the spatial structure of the urban agglomeration, the three urban groups are all present. The central degree of the Pearl River Delta is closest to 1, the space structure is the best, and the high city has no strong monopoly to promote the development of the surrounding area. The small and medium-sized cities can also develop healthfully under the radiation of the high cities. The value and the first degree of the economic relation of the Pearl River Delta are larger than the other two cities. The spatial interaction force of the city group of the Pearl River Delta is stronger and the radiation ability of the first city is stronger. Then, according to the connotation of urban agglomeration space efficiency, the index system of space efficiency measurement is established from the comprehensive angle of human flow, logistics and information flow, and the overall space efficiency of the three big cities in China from 1995 to 2014 is analyzed by data envelopment analysis. The spatial efficiency and its evolution characteristics of different urban groups are explored, and the spatial efficiency of the Pearl River Delta and Beijing Tianjin Hebei is higher than that of the Yangtze River Delta. Based on the calculation of the spatial efficiency of the urban agglomeration, the hypothesis of this paper is proposed based on the fitting diagrams of the various indexes of the urban agglomeration space organization. Finally, the production function is used as the empirical part of this paper. On the basis of the analysis, the empirical test model is built on the basis of the model, the regression analysis is carried out by the fixed effect of panel data, and the relevant conclusions are drawn according to the empirical results. The conclusion shows that the population size, the population density and the spatial economic relation of the three major urban agglomeration in China are constantly improved, and the overall spatial structure of the city is constantly strengthened; There is an inverted "U" relationship between the total population size of the population and the spatial efficiency of the urban agglomeration. The population density of the urban agglomeration has a negative influence on the spatial efficiency of the urban agglomeration. The increase of the centrality and the first degree can promote the improvement of the spatial efficiency of the urban agglomeration, and the degree of improvement of the spatial efficiency is with the change of the total population size of the urban agglomeration. When the total population size of urban agglomeration is relatively small, the central degree and the first degree of urban agglomeration have obvious influence on the urban spatial efficiency. When the population size of the urban agglomeration is larger and the urban agglomeration is gradually mature, the influence of the central degree and the first degree on the spatial efficiency of the urban agglomeration is gradually weakened; the degree of economic relations within the urban agglomeration and the degree of the urban agglomeration are more than that of the urban agglomeration. There is a positive correlation between efficiency. Finally, an empirical analysis of the effect of urban group spatial organization on efficiency is given as the main basis for the policy suggestions on the optimization of urban agglomeration space organization.
