【摘要】：以關(guān)中城市群為研究區(qū),選取2004年和2014年兩個截面數(shù)據(jù),構(gòu)建服務(wù)業(yè)綜合實力指標(biāo)體系,從聯(lián)系強度、服務(wù)功能和競合關(guān)系三個角度出發(fā),借助引力模型、城市流模型、地緣經(jīng)濟關(guān)系模型對關(guān)中城市群服務(wù)業(yè)空間相互作用進行測度。結(jié)果表明:(1)關(guān)中城市群聯(lián)系強度逐年增大,地區(qū)差異較大,呈現(xiàn)出以西安為中心的"中心—外圍"空間結(jié)構(gòu);(2)服務(wù)功能差異較大,外向服務(wù)功能高度集聚于中心城市,城市流強度也較大,外圍城市服務(wù)業(yè)外向性較差;(3)競合關(guān)系在與中心城市之間以互補型關(guān)系為主,外圍服務(wù)業(yè)欠發(fā)達城市之間競爭型關(guān)系占主導(dǎo),整體上向競爭與互補不確定型演變。
[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.
