【摘要】：城镇化的健康发展将为经济的可持续发展提供强劲的动力,随着城镇化进程的不断加快,我国面临着城市规模的合理选择和优化问题。城市规模过小,不利于城市现有土地、公共服务设施等资源的充分利用;城市规模过大,往往会造成资源的过度利用,导致拥挤成本上升等问题。因此,“优先发展大城市,还是小城市,抑或是大中小城市协调发展”成为学术界争论的焦点。现有文献对城市规模的合理性研究忽视了城市功能分工。城市功能分工是通过经济效率影响城市规模的重要经济变量。从城市功能分工的视角,以城市的生产效率作为评判标准,研究城市的合理规模,以期提高城市资源的利用效率,降低“大城市病”的代价。城市集聚经济和不经济的共同作用决定了城市的经济效率和合理规模。城市生产效率随着城市规模的扩大呈先增加后减少的倒U型变化,且城市规模扩大带来的边际收益与城市功能分工有着密切的关系。选取2003年至2012年中国沿海地区除港澳台以外11个省区的114个地级以上城市的面板数据为样本,在Henderson的城市模型的基础上,加入城市功能分工、城市网络连通性等变量,运用计量模型对城市规模进行实证研究。首先,对各城市的功能分工指标进行测度并对其进行空间相关性检验;其次,运用面板数据模型验证城市的生产效率与城市规模呈倒U型特征;再次,分别选取三种空间权重矩阵进行空间滞后计量模型和空间误差计量模型的回归分析;最后,从城市功能分工的角度,根据计量模型回归结果和城市现有的约束条件,估计城市合理规模的范围,并提出促进城市发展的政策建议。研究结论如下:第一,城市间的功能分工存在着明显的空间相关性,且呈一定的规律分布,中心城市主要承担产业链中附加值高的环节,外围城市主要承担产业链的其他环节;第二,城市规模的边际收益随着功能分工的转变而改变,城市的合理分工对促进城市达到其合理规模起着重要的作用;第三,从城市功能分工的视角看,在现有分工约束条件下,中国沿海地区城市规模发展不均衡,天津、上海、南京、广州、深圳等17个城市规模偏大,约65%的沿海城市规模偏小。因此,城市应加强与其周边城市的分工协作,优化资源配置,充分发挥国内外市场作用,促进大中小城市的规模协调发展。
[Abstract]:The healthy development of urbanization will provide a strong driving force for the sustainable development of economy. With the acceleration of urbanization process, China is faced with the problem of reasonable choice and optimization of urban scale. The full use of resources, such as public services, and the fact that the size of a city is too large, often resulting in overutilization of resources, resulting in higher congestion costs, etc., therefore, "give priority to the development of large cities or small cities," Whether it is the coordinated development of large, medium or small cities "has become the focus of academic controversy. The existing literature on the rationality of urban scale research ignored the division of urban functions. Urban functional division of labor is the heavy impact of economic efficiency on the scale of cities." From the perspective of urban functional division of labor, Taking the production efficiency of the city as the criterion, the reasonable scale of the city is studied in order to improve the utilization efficiency of the city resources. Reducing the cost of "big city disease". The combined action of urban agglomeration economy and uneconomic economy determines the economic efficiency and reasonable scale of the city. With the expansion of the urban scale, the urban production efficiency increases first and then decreases the inverted U-shaped change. Moreover, the marginal income brought by the expansion of urban scale is closely related to the division of urban functions. The panel data of 114 prefecture-level cities in coastal areas of China from 2003 to 2012, except Hong Kong, Macao and Taiwan, are selected as samples. On the basis of Henderson's urban model, this paper applies the econometric model to the empirical study of urban scale by adding variables such as urban function division, urban network connectivity and so on. To measure the functional division of labor of each city and test its spatial correlation; secondly, using panel data model to verify that the urban production efficiency and urban scale are inverted U-shaped characteristics; third, Three kinds of spatial weight matrices are selected for regression analysis of spatial lag measurement model and spatial error measurement model. Finally, from the perspective of urban functional division of labor, according to the regression results of the measurement model and the existing constraints of the city, The conclusions of the study are as follows: first, the functional division of labor among cities has obvious spatial correlation and is distributed regularly. The central city mainly undertakes the high value-added links in the industrial chain, while the peripheral cities mainly undertake the other links of the industrial chain. Second, the marginal income of the urban scale changes with the transformation of the functional division of labor. The rational division of labor plays an important role in promoting the city to reach its reasonable scale. Thirdly, from the perspective of urban functional division, under the constraints of the existing division of labor, the scale development of cities in the coastal areas of China is not balanced, Tianjin, Shanghai, 17 cities, such as Nanjing, Guangzhou and Shenzhen, are on the large side, and about 65% of the coastal cities are small. Therefore, cities should strengthen the division of labor and cooperation with their neighboring cities, optimize the allocation of resources, and give full play to the role of the domestic and foreign markets. To promote the coordinated development of the scale of large, medium and small cities.
