基于DEA模型的京津冀城市化相对效率评价

Relative Urbanization Efficiency Evaluation of Beijing-Tianjin-Hebei Region Based on DEA Model

本文对京津冀城市化相对效率进行了比较全面的评价分析。首先,本文利用2006-2015年十年间京津冀13个城市的面板数据,对各城市的城市化相对效率进行了Malmquist指数动态评价,结果显示,除天津市城市化相对效率下降外,其余各市的城市化效率均处于上升态势。其次,利用2015年京津冀13个城市的截面数据,运用DEA-BBC模型以及投影分析对各城市的城市化效率进行了静态评价,发现大多数城市具有DEA有效性,同时投影分析结果显示较低的投入要素非集约化程度决定了这些城市的城市化效率较低。最后,本文给出了结论和相应的政策建议。

This paper carries on comprehensive analysis about the relative urbanization efficiency of Beijing-Tianjin-Hebei region. First of all, based on ten years＂ panel data between 2006 and 2015 of 13 cities of Beijing-Tianjin-Hebei region and nalmquist index, the author calculates their urbanization efficiency. According to the results, urbanization efficiency are on the rise except for Tianjin. Secondly, utilizing Beijing-Tianjin-Hebei cross-section data of 13 cities in 2015 and DEA - BBC model to evaluate the static urbanization efficiency. I find that most of the cities with DEA validity, and projection analysis show that the lower inputs of intensive degree determines the city＇s low urbanization efficiency. Finally, the article gives conclusion and the corresponding policy recommendations
