京津地区空间开发效率研究

Research on the Efficiency of Spatial Development in Beijing-Tianjin Region

以京津地区为研究对象,从区域城市化的角度构建评价指标体系,运用数据包络分析(DEA)模型和方法,对近14年京津地区空间开发的综合效率、纯技术效率和规模效率进行研究。结果表明:从总体上看,京津地区空间开发效率较好,其中技术效率平均值最高;全部评价年度处于规模收益不变和规模收益递增的状态;投影分析表明有7年存在投入冗余和产出不足现象。最后提出京津地区空间开发应继续加大技术投入,优化资源配置,适度控制资源投入规模,从而实现DEA综合有效。

Taking Beijing-Tianjin Region as the research sample,from a point of regional urbanization to build evaluation index system,the integrated efficiency,pure technical efficiency and scale efficiency of spatial development in Beijing-Tianjin Region in 14 years is evaluated by using the DEA module and method in this paper.The results indicate that：1）In general,the efficiency of spatial development is better,in which pure technical efficiency is the maximum value.2）All years are in the status of increasing or constant returns to scale. 3）Analysis of the projection shows that redundant input and inadequate output exist in seven years. In order to achieve effective, spatial development in Beijing Tianjin Region should increase the technical inputs, optimize the allo cation of resources and control the input scale.
