Abstract: This paper constructs the evaluation index system of equestrian tourism suitability on the basis of three dimensions: equestrian tourism resources, tourism industry development and market potential. It also takes TOPSIS-Entropy weight method and obstacle factor model to measure and evaluate the suitability and obstacle factors of equestrian tourism in China from 2015 to 2018 with 31 provinces(excluding Hongkong, Macao and Taiwan) as research samples. The results show that: (1) Within the research range, the suitability of equestrian tourism in China was at a medium level on the whole, with a slight decrease in the resource dimension, and a significant increase in the industrial dimension and market dimension. (2) Equestrian tourism in all provinces were still in their infancy, and their suitability showed spatial differentiation as three types: relatively suitable, moderately suitable and weakly suitable. (3) The 31 provinces had different suitability in different dimensions. Inner Mongolia had better suitability in resource dimension. Jiangsu, Guangdong, Zhejiang and Shandong had strong advantage in industrial dimension. Shanghai and Beijing were more suitable in market dimension. (4) The obstacle factor analysis shows that equestrian tourism resources were the main factor restricting the development of equestrian tourism in 31 provinces. The obstacle factors in economically developed provinces manifested as an inversion phenomenon showing that the industrial dimension and market dimension were better, but the shortcomings of resources dimension was prominent. The distribution of obstacle factors in ethnic minority areas was relatively balanced, and the resource conditions had certain advantages, but the industrial development and market conditions were relatively backward. Finally, this paper puts forward countermeasures and suggestions for the development of equestrian tourism in China according to the conclusion of the study.
