摘　　要：首先建立反映城市综合实力的指标体系,然后运用因子分析法测算城市综合实力得分,并以此为基础构建加权Voronoi图,从市域、省域及跨省域等多层级核心—边缘视角研究广东与广西35个城市的经济影响区,得出从2002—2010年各城市经济影响范围的空间变化:实力弱—弱城市之间的空间吸引范围基本不变,强—弱之间有扩展趋势,强—强之间有缩小趋势,两广核心—边缘结构稳定。为进一步考虑城市等级差异性,对比分析广东与广西不同等级城市的经济腹地,研究发现,这种腹地结构是多层级、嵌套式的。理论上,各边缘区应依托其核心城市的发展,提高同核心城市之间的连通性,加强区域合作。By establishing an evaluation indexes system and using factor analysis method to calculate the city comprehensive power, this paper generates the weighted Voronoi diagram from the multi-level core-periphery perspective to delimitate the 35 cities＇ economic influence regions of Guangdong and Guangxi. We find that the space attractive scopes hardly change between weak- weak cities, but tend to be expanded between strong- weak cities, and shrunk between strong - strong cities. The core-periphery structure is stable. Further, to consider the cities＇ level difference, we analyze city economic hinterland from urban, provincial and cross-provincial level in Guangdong and Guangxi. The result shows that the hinterland is a multi-level and nested structure. Theoretically, each region should improve the connectivity to its central cities, and strengthen regional cooperation.
