城市化效率的时空测度与省际差异研究

The Time-space Measurement of Urbanization Efficiency and Provincial Differences

城市化效率作为衡量城市化质量内涵的重要标准,已成为城市经济协调运转的逻辑起点。基于数据包络分析法(DEA),利用Malmquist效率指数,以2005—2010年为样本研究时段,对中国31个省区(市)的城市化效率分别进行了动态测算。同时,运用DEA-BCC模型对其规模报酬和非集约度进行静态测算。结果表明:天津、福建、青海等17个省区(市)城市化效率较低;河北、安徽、四川等19省区(市)仍处于非有效且投入要素非集约度状态。文章最后提出要提高土地利用效率、发展集约型产业、实施科技推动的城市化道路等提高城市化效率的政策建议。

As a measuring important standard for the quality connotation of the urbanization, urbanization efficiency becomes the logic starting point of the coordinate operation of urban economy. Based on the data envelope analysis （DEA） and Malmquist efficiency index, this article carries on the static measurement of the urbanization efficiency on 3 l provinces in China through 2005-2010 years as the sample study period. At the same time, the article carries on the static measurement of returns to scale and non intensive degree with the aid of DEA-BCC. The results show that： the urbanization efficiency of 17 provinces （eg. Tianjin, Fujian, Qinghai etal） is low; Hebei, Anhui, Sichuan etal 19 provinces are still in non effective and devoted elements exist non intensive degree. Aiming at the dynamic and static calculation results, finally, improving land use efficiency and developing the intensive industry as well as implementing the urbanization way under the science and technology promoted become the policy suggestion.
