【摘要】：城市群是全球城市化发展主流趋势的伴随物,也是我国新型城镇化的主体形态。城市群层级体系的完善与否直接影响到区域经济整体功能的充分发挥。本文以成渝城市群为研究对象,在对国内外相关文献、理论的梳理基础上,研究成渝城市群层级体系形成及其协调。研究成渝城市群层级体系有利于推动长江经济带上游经济区协调发展。首先,在对成渝城市群地域构成界定基础上,分析成渝城市群层级体系现状。研究结果显示,无论是经济发展还是城镇化水平,成渝城市群都呈现出明显空间差异和空间分形特征。进行层级分析可知,成渝城市群层级体系不完善,缺乏超大城市,且大中城市数量不足,小城市数量多但发展水平低。其次,对成渝城市群层级体系实证研究。研究表明,成渝城市群层级体系基本符合齐普夫定律。但帕累托指数略大于1,属于城市人口分布差异较大、首位城市不强的城市体系。实证分析得出:产业结构、科技发展水平及融资能力是城市群等级规模的重要影响因素。最后,依据成渝城市群层级体系现状,综合考虑各城市发展规划及发展潜力,提出针对性的成渝城市群层级体系完善路径:继续提高成都、重庆城市经济辐射势能,强化其辐射带动作用;将南充、绵阳、达州作为副中心城市,促进它们发展为特大城市,以弥补特大城市断层短板;促进泸州、自贡、遂宁、内江、乐山等城市向Ⅰ型大城市发展;继续推动原有中等城市规模扩展,并选择有潜力的小城市发展为中等城市;促进小城市规模扩张,更好的发挥链接城乡的纽带作用。
[Abstract]:Urban agglomeration is the main form of new urbanization in China as well as the main trend of global urbanization. The perfection of urban agglomeration hierarchy system directly affects the full play of the whole function of regional economy. Taking Chengdu-Chongqing urban agglomeration as the research object, this paper studies the formation and coordination of the hierarchical system of Chengdu-Chongqing urban agglomeration on the basis of combing the relevant literatures and theories at home and abroad. The study of the hierarchical system of Chengdu-Chongqing urban agglomeration is conducive to the coordinated development of the upstream economic zone of the Yangtze River Economic Belt. Firstly, on the basis of defining the regional composition of Chengdu-Chongqing urban agglomeration, the present situation of Chengdu-Chongqing urban agglomeration hierarchy system is analyzed. The results show that there are obvious spatial differences and fractal features in Chengdu-Chongqing urban agglomeration both in terms of economic development and urbanization level. The hierarchical analysis shows that the hierarchical system of Chengdu-Chongqing urban agglomeration is not perfect, lacking of megacities, and the number of large and medium-sized cities is insufficient, and the number of small cities is more than that of small cities, but the level of development is low. Secondly, empirical study on the hierarchical system of Chengdu-Chongqing urban agglomeration. The study shows that the hierarchical system of Chengdu-Chongqing urban agglomeration basically conforms to Zipf's law. However, the Pareto index is a little more than 1, which belongs to the urban system which has great difference in population distribution and is not strong in the first city. The empirical analysis shows that the industrial structure, the level of scientific and technological development and the ability of financing are the important factors affecting the scale of urban agglomeration. Finally, according to the present situation of Chengdu-Chongqing urban agglomeration hierarchy system, and considering the development planning and development potential of each city synthetically, the paper puts forward the way to perfect the hierarchical system of Chengdu-Chongqing urban agglomeration: continue to improve the urban economic radiation potential energy of Chengdu and Chongqing. Strengthening its radiation-driven role; taking Nanchong, Mianyang and Dazhou as sub-central cities to promote their development into mega-cities to make up for the fault plates in mega-cities; and promoting Luzhou, Zigong, Suining and Neijiang, Leshan and other cities develop to type I big cities; continue to promote the expansion of the original medium-sized cities, and choose the potential small cities to develop into medium cities; promote the scale expansion of small cities and play a better role as a link between urban and rural areas.
