【摘要】：以关中城市群为研究区,选取2004年和2014年两个截面数据,构建服务业综合实力指标体系,从联系强度、服务功能和竞合关系三个角度出发,借助引力模型、城市流模型、地缘经济关系模型对关中城市群服务业空间相互作用进行测度。结果表明:(1)关中城市群联系强度逐年增大,地区差异较大,呈现出以西安为中心的"中心—外围"空间结构;(2)服务功能差异较大,外向服务功能高度集聚于中心城市,城市流强度也较大,外围城市服务业外向性较差;(3)竞合关系在与中心城市之间以互补型关系为主,外围服务业欠发达城市之间竞争型关系占主导,整体上向竞争与互补不确定型演变。
[Abstract]:Taking Guanzhong urban agglomeration as the research area, this paper selects two cross-section data of 2004 and 2014 to construct the comprehensive strength index system of service industry. From the three angles of connection strength, service function and competing relationship, with the help of gravity model, the urban flow model is established. The geo-economic relation model measures the spatial interaction of service industry in Guanzhong urban agglomeration. The results show that: (1) the intensity of Guanzhong urban agglomeration is increasing year by year, and the regional difference is great, showing the spatial structure of "center-periphery" with Xi'an as the center; (2) the service function is quite different, the outward service function is highly concentrated in the central city, the intensity of urban flow is also large, and the extroversion of service industry in peripheral city is poor; (3) the relationship between competition and cooperation is mainly complementary with the central city, and the competitive relationship between the underdeveloped cities in the peripheral service industry is dominant, and the overall evolution is towards the competition and complementary uncertainty.
