摘要
应用分析中常用的引力模型对重庆市的城市经济影响力进行分析。依据重庆与其周边的成都、西安、武汉、长沙、贵阳、昆明等6省会城市对区域中各区县引力大小的对比,将重庆市对其周围区域经济影响力划分为四类不同强度的区域,即:重庆市引力大于其他城市引力总和的区域为强影响区,大于其他城市引力最大值的区域为次强影响区,大于其他城市引力平均值的区域为中度影响区,小于其他城市引力平均值的区域为弱影响区。结果表明:重庆市的强经济影响区已经扩张到四川与贵州境内,重庆与成都、贵阳的影响力均已透过断裂点渗透到对方区域并合力形成城市影响力高值带;与昆明、西安、长沙、武汉的引力断裂点在四省边界地区的县市境内,这些地区一般距离省会城市200—300km以上。引力强度等级区域的划分对于划定重庆市主体功能区具有较明晰的借鉴意义。
Using the gravity model of the spatial interaction that analysing the urban economic impact-force of Chongqing. Based on the contrast of attractive force between Chongqing and its neighboring central city （Chengdu, Xi＇an, Wuhan, Changsha, Guiyang and Kunming）, we can divide the region into four different parts, namely ： The first part which Chongqing gravity is greater than the sum of the other cities in the region, is named strong gravitational influence zone; The second part which Chongqing gravity is greater than maximum gravity-affected of the other cities in the region, is named secondary strong zone; The third part which is greater than the average of other cities in ＇the region, is named moderate gravity-affected zone; And the fourth part which smaller than the average of other cities in the region, is the weak gravitational influence zone. The results show that： the strong economic impact zone has been expanded to Sichuan and Guizhou provinces; a high gravitational influence value belt is formed between Chengdu, Chongqing and Guiyang, for their influence have penetrated through the breaking point into each other zone; the gravitational break points between Chongqing and the other ceties （Kunming, Xi＇an, Changsha, Wuhan） are located in the border areas of the four provinces, these areas are usually away over 200-300km from the provincial capital city. Dividing the Gravitational strength grade of the region can be referenced by the Major Function Oriented Zoning in Chongqing.
