基于Malmquist指数法的城市增长效率及差异研究——以内蒙古的20个城市为例

City growing efficiency and differences based on the Malmquist index: taking twenty cities of Inner Mongolia

基于内蒙古2000-2009年间的面板数据,运用非参数的Malmquist指数法及DEA模型,分析了内蒙古20个城市的全要素生产率变动情况及不同区域城市的差异。研究表明,内蒙古城市增长的全要素生产率主要依靠技术进步推动,而技术效率水平较低;内蒙古城市效率表现出西部高东部低的明显区域差异;东西部城市的产业结构差异所导致的对新技术敏感性的不同是区域全要素生产率差异的重要原因;此外,科技、教育和文化中心区位上的差别也是导致城市增长效率差异的因素。

By using non -parametric Malmquist index and the DEA model and the panel data of 2000 - 2009 of the In- ner Mongolia data, this essay analyzes the total factor productivi- ty changes in different regions and difference of the 20 cities in Inner Mongolia. The results show that urban growth in total fac- tor productivity in Inner Mongolia mainly relies on technological progress for the promotion and the technical efficiency level is lower; the urban efficiency of the Inner Mongolia shows obvious regional characteristics, high in west and low in east. Further studies show that the differences of sensitivity to the new technol- ogy which are caused by industrial structure is an important fac- tor in total factor productivity differences. And the location of technology, education and cultural center are also the factors in the formation of the efficiency of urban growth differences.
