Abstract：Analyzing urban tourism efficiency and its influence factors is helpful to optimize tourism resource investment & combination, and enhance utilization ability. With DEA ( Data Envelopment Analysis) , the panel data of 18 cities' tourism industry of Henan province from 2012 to 2014 were employed to analyze and evaluate overall efficiency, technical efficiency, scale efficiency and returns to scale of tourism resource utilization, based on which the main factors affecting urban tourism efficiency were concluded. The results show that the overall efficiency, technical efficiency, scale efficiency of urban tourism in Henan province are at a middle level; the variance of different kinds of efficiency among cities and regions are large, and the overall efficiency variance tends to get larger, variance of both technical efficiency and scale efficiency are gradually decreasing; about 72% cities are at the stage of increasing returns to scale and these cities are not in Zheng-Bian-Luo region. Finally, this paper discusses macroscopic, meso and microscopic factors that influence urban tourism efficiency on different levels.
