摘要
以徐州都市圈为研究对象,通过引力模型计算2006年~2016年中心城市与各个次级城市之间的经济联系,并结合都市圈内城市发展的变异系数和泰尔指数,分析都市圈内部经济发展时空差异.研究结果表明:2006年~2016年徐州都市圈的经济发展水平在随着时间的推移不断提高,内部经济发展差异总体在不断缩小.但是都市圈内中、东部之间经济发展差异有加大的趋势.徐州作为都市圈的中心城市对外经济辐射功能显著,与其经济联系密切的几个城市主要集中在距离徐州市80 km范围内的淮北市、宿州市和枣庄市,其余城市因为受到自身的城市规模、经济发展水平和地理位置等因素的影响,与中心城市的经济紧密度相对较弱,呈现明显的空间差异.
Taking Xuzhou Metropolitan Circle as the research object,this paper calculates the economic relationship between the central city and each secondary city by gravity model,and analyzes the spatial and temporal differences of the economic development in the metropolitan circle by combining the coefficient of variation and the Thiel index of urban development in the urban circles in the 2006~2016.The results show that:in 2006~2016,the economic development level of Xuzhou metropolitan Circle is increasing with the passage of time,and the difference of internal economic development is decreasing.But there is an increasing trend of economic development differences between the central and eastern cities.Xuzhou,as the central city of the metropolitan area,has a significant external economic radiation function,and several cities with close economic ties mainly focus on Huaibei,Suzhou and Zaozhuang in the range of Xuzhou 80 km,and the rest of the cities are influenced by their own urban scale,economic development level and geographical location,And the central city's economic tightness is relatively weak,showing obvious spatial differences.
