中文摘要：

本文利用DEA—Malmquist指数模型对2005年-2014年新疆城市综合效率及其变化情况进行了分析，结果显示：新疆城市综合效率的提高主要来自规模效率的提高；新疆18个城市中仅昌吉市实现了纯技术效率和规模效率的增长；新疆中等规模城市的发展得益于纯技术效率和规模效率的提高；南疆地区城市综合效率较差。为此建议，应加大对中等城市和南疆地区城市的投入力度，加快企业技术创新能力的培养，提高大城市的“转化”能力，加快政府职能的转变，从而提高新疆城市综合效率，加快新疆城市经济发展。

英文摘要：

In this paper, urban comprehensive efficiency and its changes from 2005 to 2014 in Xinjiang were analyzed by using the DEA - Malmquist index model. The results show that the increase in the overall urban efficiency of Xinjiang was mainly from improving the scale efficiency; among 18 cities in Xinjiang, only the City of Changji realized the pure technical efficiency and scale efficiency growth; development of medium - sized cities owed much to the improvement of pure technical efficiency and scale efficiency; urban comprehensive efficiency was poor in southern Xinjiang. For this purpose, it is of necessity to increase the investment in the medium - sized cities and cities in southern Xinjinag, accelerate the training of enterprise technology innovation ability, improve the city ＂transformation＂ability, speed up the transformation of government functions, to improve the comprehensive efficiency and accelerate the economic development of cities in Xinjiang.
