中文摘要：

基于2001--2014年城市旅游业投入一产出数据，结合DEA、GIS及典型相关分析方法，以辽宁省所辖14个地级市为例，对城市旅游业效率的时空演变及其驱动因素进行了实证研究。结果表明：①辽宁省城市旅游业效率水平差异明显，但整体差异性呈显著减弱趋势，效率水平长期增长呈显著提升态势。②辽宁省城市旅游业效率空间集聚效应较弱，随时间演进区域整体生产率水平提升显著，城市旅游业效率增长率差异呈减弱趋势；各城市技术进步水平、生产率水平和纯效率水平发展较好，但空间资源管理水平低下，导致城市规模越大、城市规模效率水平越低，沈阳和大连两大中心城市规模效率水平一直处于倒“u”型曲线左下方。③存在相关社会经济指标驱动城市旅游业效率提升，应注重相应社会经济指标的均衡发展，促进我国城市旅游业高效率与可持续发展。希望研究结果能为我国城市旅游业“优质“建设及高效率发展提供借鉴。

英文摘要：

On the basis of the city tourism input and output data in 2001 - 2014, using DEA, GIS combined with canonical correlation analysis （CCA） method, this paper attempted to analyze the space- time evolution and drive factors of city tourism efficiency in 14 cities of Liaoning Prov- ince. The results showed that：① City tourism efficiency level was different significantly in Liaoning Province. But the overall difference showed weak- ening trend and the efficiency level of long - term growth showed increase trend.②The spatial agglomeration effect of city tourism efficiency was weak in Liaoning Province. The regional overall productivity level was increase significantly with time and the growth rate difference of city tourism efficiency showed weakening trend.The technological progress level, productivity level and pure efficiency level was good in each city. But the low space re- source management level led that the bigger cities, the lower city scale efficiency level. It led to the city scale efficiency level of Shenyang and Dalian was inverted＂U＂curve at the lower left. ③The relevant social and economic indicators improved the efficiency of urban tourism. In order to promote sustainable development of urban tourism, we should pay attention to the balanced development of these indicators.
