Analysis of Spatial Agglomeration and Equilibrium Characteristics for Population and Economic in China during 2001-2010
使用增量分析和失衡指数，研究2001-2010年中国地级市尺度人口与GDP的空间集聚和均衡特征，发现人口与经济向沿海、沿江等轴线集聚，总体趋于均衡，但东强西弱格局未变。
This paper employs Increment Analysis and Imbalance Index to examine the spatial agglomeration and equilibrium characteristics of population and GDP in China at prefecture scales during 2001-2010.(1) There is strong regularity in spatial change process between China's population and economy, mainly reflected by the trend of aggregated distribution in the coastal, riverside, other major spatial development axis and the core cities in central and western;(2)China's population and economy move to the spatial equilibrium in general. The population agglomeration in the eastern region is obvious; the population proportion of the mid-west and northeast area showed a decreasing trend, while the proportion of GDP in the middle-western regions increased during this period, and this trend is just cross to population trend in the middle-western regions. These lead to the decrease of the potential difference within the agglomeration of population and economy elements;(3)The east-west regional gap is still the main development gap. The situation that the population and economic elements agglomerate to the eastern region highly did not change fundamentally and China's spatial development pattern-strong in the East and weak in the Westhas no fundamental change.
