We used panel data for 31 Chinese provinces from 2001 to 2009 and entropy methods to evaluate regional tourism resources endowment. Combined with regional tourism revenue, we constructed an asynchronous index and quantitatively evaluated every area's asynchronous phenomenon regarding tourism resources. We found that Chinese mainland tourism resources have asynchronous phenomenon: tourism is positively asynchronous in the east (Yangtze River Delta, Pearl River Delta and Beijing-Tianjin region) and negatively asynchronous in central and western China. The total efficiency of tourism resources in eastern China is mainly driven by pure technology efficiency and by scale efficiency in western China. In addition to some provinces, the ranking of provincial total efficiency and the asynchronous index has a strong positive correlation. We conclude with several suggestions for the development of tourism resources across China.
