区域发展差距一直是中国区域协调发展所面临的重要问题,经济和人口的空间分布态势作为区域发展空间均衡过程的体现,与区域差距的形成有密切关联.通过计算1952年至2005年中国经济重心和人口重心的地理坐标以及重心间的空间重叠性与变动一致性,刻画了53年间我国经济和人口空间分布的耦合态势,证明了其与区域差距的大小高度相关.在构建经济、人口重心空间耦合过程的作用机制模型的基础上,用均衡点跃迁和势能差转化解释了区域发展的空间均衡过程,揭示了内生和外部因素在其中的作用机制,提出了区域发展差距的"多阶段倒U形"的演变规律.并据此分析了1952年以来中国区域发展空间均衡过程周期性变化的动因,并对促进区域协调发展的途径进行了讨论.
區域髮展差距一直是中國區域協調髮展所麵臨的重要問題,經濟和人口的空間分佈態勢作為區域髮展空間均衡過程的體現,與區域差距的形成有密切關聯.通過計算1952年至2005年中國經濟重心和人口重心的地理坐標以及重心間的空間重疊性與變動一緻性,刻畫瞭53年間我國經濟和人口空間分佈的耦閤態勢,證明瞭其與區域差距的大小高度相關.在構建經濟、人口重心空間耦閤過程的作用機製模型的基礎上,用均衡點躍遷和勢能差轉化解釋瞭區域髮展的空間均衡過程,揭示瞭內生和外部因素在其中的作用機製,提齣瞭區域髮展差距的"多階段倒U形"的縯變規律.併據此分析瞭1952年以來中國區域髮展空間均衡過程週期性變化的動因,併對促進區域協調髮展的途徑進行瞭討論.

Regional gap is an important problem that the regional development of China is facing. The distribu-tion of economy and population, as an embodiment of the spatial equilibrium process of regional development, has a close relation with the state of regional gap. Using grawty models, it works out the center of economic gravity and population gravity (abbr. CEG and CPG), illustrates the coupling process by measuring the overlap-ping of two centers of gravity and the consistency of their movement, and proves that the coupling process has a high correlation with the evolution of regional gap. Then, a model of the coupling mechanism of CEG and CPG is built. Based on the model, it illustrates the spatial equilibrium process of regional development by the transi-tion of equilibrium location and the conversion of regional potential energy difference, and reveals how the inter-nal and external factors affect the process. Therefore, the authors advance a "multistage inverted-U-curve evolu-tion law" of regional gap. Finally, it analyses the mechanism of the periodic variation of regional gap in China since 1952, and brings up a discussion of the path to coordinating the regional development of China.
