城市群是未来中国城镇化的主要空间载体,研究城市群空间结构的演化特征和影响因素具有重要意义。已有文献较少从形态单中心—多中心视角研究中国城市群空间结构的演化和影响因素,而且通常采用户籍人口而非常住人口测度城市群空间结构,导致测量误差。为解决这个问题,本文采用基于人口普查的常住人口数据进行分析,并运用联合国数据对结果进行佐证。以已有文献采用客观标准界定的13个城市群为样本,使用规模-位序法则测度城市群的形态单中心—多中心程度,探究城市群的空间结构演化趋势和影响因素。结果发现,1980年代以来大多数城市群的空间结构呈现多中心化趋势;人均GDP水平的提高和人口规模的增加是导致城市群空间结构多中心化的主要原因。因此,政府对于空间结构偏多中心的城市群,应强化城市间的交通联系和政策一体化,获取更大的发展红利;对于个别处于单中心化阶段的城市群,政策导向则避免过早地多中心化。 |

With the significant increase of social and economic interactions among constituent cities,city clusters have become the most striking geographic phenomenon in the twenty-first century. In the latest regional development strategy,city clusters have been positioned as the main spatial carriers of socioeconomic activities by the Chinese government. Although an increasing number of scholars has described the characteristics and proposed definitions of city clusters,there have been surprisingly few studies on the morphological change and influencing factors of city clusters' spatial structure based on population data. In most existing empirical studies on city cluster,instead of permanent resident population,registered household (hukou) population was used to measure city clusters' spatial structure and this introduces error. Hence,in this study we used two different sources of data-permanent resident population from the Chinese Census,and population of urban agglomerations released by the United Nations population division. Our sample is comprised of 13 city clusters.. Rank-size rule was applied to measure the morphological characteristics. The principal objective of this study is to examine the change and influencing factors of the spatial structure of Chinese city clusters. Our descriptive statistics show that there was a clear tendency towards polycentricity of city clusters during 1990-2010. Using two panel data analysis techniques (FE and FGLS) and different databases,we found that all else being equal,the spatial polycentricity of the city clusters is mainly associated with the increases of GDP per capita and population size. Most city clusters are in the stage of polycentricity,and only a few remain in the earlier monocentric stage. These findings have important policy implications for the development of urban clusters. For most city clusters with a polycentric tendency,the governments should promote integration within city clusters through transportation and regional coordination policies that strengthen the exchange of production factors and improve economic performance. For the few city clusters of monocentricity,however,the governments should avoid introducing polycentricity oriented policies too soon,which could be harmful to their economic performance. Due to methodological and data limitations,the endogenous problem between spatial structure and economic development is difficult to solve. The spatial structure of city clusters can be regarded as both a cause and a consequence of economic development. Hence,this two-way relationship might be correlative rather than causal. Further work should push forward in this regard to identify the real cause-effect. In addition,an increasing literature uses economic and transportation data to analyze city clusters from the perspective of functional linkage. This represents another direction that future research should focus on. |
