摘要
通过对以往引力模型的改进,将GDP、社会消费品零售总额修正为市辖区数据,人口以市辖区常住人口为准,引入引力模型公式和断裂点公式,以广西的14个地级市为研究对象,分别计算各城市在2000年、2005年、2010和2014年四个时间节点彼此间的引力值和断裂点。结果表明:南宁的城市综合质量一直保持领先地位;以南宁、柳州为核心的区域城市群逐渐形成;区内经济格局呈"条带状"结构。最后对区域经济协同发展提出建设性的意见。
The previous gravity model is improved and the GDP,together with the total retail sales of consumer goods,is amended as the municipal data. Then with the permanent residents in the 14 municipal cities in Guangxi Province as the research object,the gravity model formula and breaking point formula are employed to calculate the attractions and breaking point among cities in the year 2000,2005,2010 and 2014. The results show that the comprehensive quality in Nanning always maintains in leading position; that the regional urban agglomeration with Nanning and Liuzhou as the core has gradually formed; that the regional economic structure develops as a＂strip＂. Finally constructive proposals are put forward for the coordinated development of the regional economy.
