Abstract: In the present work, the authors performed a study on the efficiency of 11 cities in Zhejiang province by using the Data Envelopment Analysis（DEA）to evaluate the tourism efficiency of these cities from 2002 to 2011, on the basis of which, space-time differences and variations of tourism efficiency were analyzed in detail. Results showed that differences among 11 cities were obvious, although the overall efficiency of Zhejiang province maintained relatively high. Tourism efficiency were related to the regional tourism economy, and fluctuated on the top level with the expansion of tourism economy. As a whole, tourism efficiency constantly improved, while efficiency differences among cities became smaller and tend to be stable. Diverse problems existed among 11 cities: Wenzhou and Jinhua are necessary for high utilization of tourism technology. Quzhou and Lishui which are in the stage of increasing returns to scale should appropriately increase the tourism investment. Ningbo, Wenzhou, Shaoxing, Jinhua and Taizhou should pay attention to the scale control of tourism industry.

摘要： 本文采用数据包络分析方法（DEA），分析了2002~2011年浙江省11个地级市旅游业效率时空差异和变化特征。结果显示：浙江省的旅游效率总体水平较高，但依旧存在地区差异，形成了高、中、低3个层次；旅游业效率与区域旅游经济发展水平相关，随着旅游经济的扩张，旅游业效率呈现出以高效率值为顶峰的波动规律；各地市的旅游业效率总体上不断提高，地区间的效率差异不断变小并趋向稳定；旅游业效率低的城市存在不同问题特质，其中温州和金华体现在旅游业技术利用水平不足方面，处于规模递增阶段的衢州和丽水可适当扩大旅游业投资，宁波、温州、绍兴、金华和台州5市则应该注意控制旅游业规模。
