Based on Sichuan provincial data of tourism economy from 2000 to 2016, a multivariate linear regression model was built with indexes from the aspects of regional macroeconomic development, tourism resources appeal, tourism consumption demand, tourist reception capacity and transportation convenience, for an empirical analysis of the development of the provincial tourism economy. The results show that the factors significantly affecting the development of Sichuan provincial tourism economy remain to be the number of tourists and the level of local residents' consumption. Then, targeting the problems, we offer some feasible advice for the faster and better development of tourism economy in Sichuan province.
