中文摘要：

目前中国的城市旅游发展存在一种盲目扩张的现象，部分城市想通过扩大旅游业的投入（如大量兴建五星级酒店）来获取更多的旅游产出（收入），衡量一个城市旅游投入与旅游产出的比例关系是否合理是值得深入探讨的一个问题。因此本文构建了基于DEA方法的城市旅游投入产出效率即城市旅游经营效率进行评价模型，在模型中引入了修正系数的概念，以对不同区域的城市由于发展环境的不同造成的旅游产出的误差进行修正。最后对评价模型的适用进行了总结，并对未来的研究进行了展望。

英文摘要：

At present, there is a phenomenon of blind expansion in China＇s urban tourism development in some cities, which want to expand tourism industry input （such as constructing a large number of flve-star hotels） to obtain more tourism output （income） . It is a valuable deep discussion that measuring whether the proportion relationship between the urban tourism input and output is reasonable or not. Therefore, based on the DEA method this article builds the urban tourism input-output efficiency, in the process, the concept of correction coefficient is introduced to correct the error, which is caused by the different development environment in different regions. Finally, the application of evaluation models are summarized, and future prospects of the study are carried out.
