摘要从经济相互作用的强度、方向与范围的维度考虑，运用空间相互作用的数理模型，即断裂点理论模型和引力模型等方法，以县市为研究的基本单元，对江苏省南京都市圈主要县市经济的相互作用进行详细的分析和讨论。研究结果表明：江苏省南京都市圈14个县市在经济相互作用的强度、作用的方向、作用的范围等方面都存在着较大的差异，但无论是从哪一个角度看，毫无疑问，南京是江苏省南京都市圈的经济发展龙头和辐射核心。在作用的强度上来看，南京的经济作用强度稳居第一位，成为该区的发展中心；在作用的方向上，该区域内主要县市的相互作用都表现出明显倾向于中心县市和相邻地域的特征；而在作用的范围大小方面，主要县市的作用范围是不一致的，空间的层次性较为明显，南京是该区域辐射中心，并且对其他县市进行辐射方式是呈现出由中心向外层扩散的特点。在各县市今后的发展中，应该分不同类型进行指导，使县市的综合实力得到不断提高，增强区域内各县市的联系，全面培育和提升县市的竞争力，进而推进南京都市圈的全方位发展。67295

Analysis on the Economic Interaction between the Main Cities and Counties of Nanjing City Circle in Jiangsu Province

Abstract

From the strength, direction and scope of the interaction between economic point of view, using a powerful response to breaking-point theory of economic strength models and methods such as gravity models, metropolitan area and major cities and counties in Jiangsu Province Nanjing economic interactions are detailed analysis and discussion. Results of the study revealed: 14 in Nanjing, Jiangsu Province, metropolitan counties and in the interaction of economic strength, direction, roles, there are a large range of different, but whether it is seen from a perspective which, no doubt, Nanjing in Jiangsu Province, Nanjing Metropolitan economic development leader and radiation core. In role of strength degree Shang view, Nanjing of economic role strength stability home first bit, became the District of development center; in role of direction Shang, the regional within main County City of mutual role are performance out obviously tendencies Yu Center County City and adjacent geographical of features; and in role of range size aspects, main County City of role range is inconsistent of, space of level sex more obviously, Nanjing is the regional radiation Center, and on other County City for radiation way is rendering out by Center to outer diffusion of features. In the future development of the city and County, should be carried out in different types of instruction, the County's comprehensive strength has been continuously improving, strengthening regional linkages within the city and County comprehensive cultivating and promoting the competitiveness of the city and County, and promote the all-round development of Nanjing metropolis.
