摘要
通过建立多投入多产出的DEA模型,从时间和空间角度对安徽省的城市化效率进行分析.结果发现,安徽省城市化效率水平不高,存在DEA无效城市.根据Malmquist指数分析可以看出,安徽省城市效率处于不断下降的趋势,且一般来说,城市化效率越高的城市,下降速度越快,造成城市化效率变化无效率的主要原因为技术变化的无效性.建立投入导向模型,采用投影技术分析投入要素的非集约性,结果显示,安徽省非集约性具有全面性且程度较高,整体达到50%-100%,属于强非集约型,造成大量资源浪费.同时,这也是安徽省城市化综合效率低下的直接原因.
Through establishing the multiple input and output DEA model,this paper analyses the urbanization efficiency in Anhui Province from the angle of time and space,then finding that the urbanization efficiency of Anhui Province lies in the low level and there are a lot of DEA invalid cities. According to Malmquist index ,the efficiency of Anhui Province has been in a declining trend and the city with higher urbanization efficiency decreases faster generally. Then finding that the in-efficiency of urbanization is mainly caused by inefficiency of technological change. Setting up the investment orientation model,using the projection technology to analysis the non-intensive of investment, this paper finds the non-intensive of Anhui Province is comprehensive and in high degree which reaching 50%-100%, belong to the strong non-intensive,and it causes a lot of waste of resources. At the same time,this is also the direct reason why the urbanization efficiency of Anhui Province is low.
