旅游效率是衡量旅游业发达程度的重要指标。新冠肺炎疫情（COVID-19）对中国旅游业造成严重的冲击，旅游业除了面临巨大生存压力外，经营效率的检讨与提升，更是疫情常态化下旅游业发展与旅游研究新变化的重要课题。本文以新冠疫情危机为背景，以广东省21个地级市为研究对象，采用数据包络分析法，选取旅游相关投入与产出指标数据构建研究体系，对2019与2020年的城市旅游效率进行测算和分析，依据城市旅游综合效率、纯技术效率、规模效率等进行系统评测。研究发现：（1）总体而言，疫情危机反而造成各城市内部旅游经营效率提升；（2）疫情造成各城市旅游趋于同质化，效率差异呈缩小趋势；（3）旅游效率改变与经济水平高低并不完全一致，并明确城市所存在旅游资源投入冗余、产出不足等问题，藉此提出效率提升、旅游产业优化等针对性策略。

Tourism efficiency is an important index to measure the degree of tourism development. The outbreak of new coronavirus pneumonia (COVID-19) has caused a very serious impact on China’s tourism industry. In addition to facing great survival pressure, it is an important subject of tourism development and tourism research under the normalization of the epidemic. This paper takes 21 cities at the local level in Guangdong Province as the research object, adopts the data envelope analysis method, and selects the data of input and output indicators related to tourism to construct the research system. Urban tourism efficiency in 2019 and 2020 are systematically evaluated for the comprehensive efficiency, pure technical efficiency, and scale efficiency. The study found that: (1)The COVID-19 has improved the overall tourism management efficiency; (2)The epidemic has caused the tourism of various cities to homogenize and decreased the trend of efficiency difference; (3)Changes of tourism efficiency is not exactly consistent with economic level. The results clearly identify the problems of redundancy and insufficient output of tourism resources in cities. Targeted strategies are proposed for efficiency improvement and tourism industry optimization.
