Scientific assessment of urban tourism functional strength has important decision-making value and practical significance to promote cities＇ function transform into tourism.

The results showed that o- verall tourism functional strength of Chinese primary cities increased significantly, the absolute difference among cities increased, and the relative difference narrowed; three decomposed functional strength also showed similar trends. Besides, urban tourism functional strength showed regional imbalance, and location and traffic conditions, resource endowment and comprehensive strength of city are the most dominant factors that affect the functional strength of urban tourism.
