摘要:

优化与重构人口的空间分布格局是当前国家战略决策的重点研究领域之一。首先,利用2000年和2010年人口普查数据,通过帕累托指数、赫芬达尔指数和首位比重指数刻画了中国城市市域空间结构的特征及其演化;其次,从自然地理、社会经济和政府干预3个方面系统地揭示了区域空间结构形成与演化的影响因素。结果表明:① 相对于胡焕庸线以西地区,胡焕庸线以东的市域更偏向多中心;中国市域空间结构相对稳定,有微弱的向多中心发展的趋势;②市域空间结构的形成主要受政府干预影响,自然地理和社会经济的作用相对较弱。具体而言,地表粗糙程度、城市行政等级和政府支出占比会推动区域空间结构朝单中心方向发展;而土地面积、县/县级市内国家级开发区个数、市域内政府间竞争以及人均公路里程则使得空间结构朝均衡的多中心方向演进。

Abstract:

Optimizing the spatial structure of urban population distribution is one of the key strategies in China, and central government has made clear that we should adhere to the coordinated development of large, medium and small cities. At the same time, the income gap that stimulates the flow of population continues to expand, the Hukou system is becoming flexible, and the technologies in transportation, information and communication have been largely improved, which have further promoted the outward flow of the population. Hence, the focus of China’s urbanization should shift from improving the urbanization rate to optimizing spatial efficiency, and it is of great importance to understand the characteristics, evolution and the formation mechanisms of urban spatial structure. Based on the 2000 and 2010 censuses, this paper describes the features of spatial structure in Chinese prefecture-level city regions by three different indexes: Pareto exponent, HHI and Primacy index. It has found that, from the static point of view, city-regions in the southeastern side of Hu line is much more polycentric than the northwestern side ones; and from the view of dynamic process, the spatial structure is rather stable on the whole and has a weak tendency towards polycentricity. Also this paper constructs a comprehensive framework by covering the factors of physical geography, socio-economy and government intervention to systematically examine the influential factors of regional spatial structure. Traditional location theory and economic geography have confirmed the role of physical geography in economic agglomeration and urban formation, and the level of social-economic development and the government have jointly decided the development and evolution of regional spatial structure in China. Our empirical results show, the spatial structure of Chinese city-regions is mainly affected by the role of government intervention, and physical geography and social economic factors on regional spatial structure is relatively limited. Specifically, surface roughness, hierarchy level of cities and government expenditure ratio will bring the regional spatial structure into monocentricity, while administrative land area, the number of NDZs, competition between local governments, and per capita road mileage can make the spatial structure more polycentric. Our previous studies have come to the conclusion that, prefecture cities with a more monocentric spatial structure have a higher labor productivity. Combined with this, the conclusions of this paper have important implications for the future development of new urbanization in China. The finding that urban spatial structure is mainly affected by the visible hand of government might not be a good sign. Government policies are often multi-targets, and its goals, in most cases, are not for the improvement of the spatial structure, but only an additional effect. This also explains why the governmental interventions are often contradictory with each other.

Key words: monocentricity, polycentricity, city-region spatial structure physical, government intervention, geography
