The integration and interactive development of tea industry and tourism is the inherent need of both industries, which is of great significance to break the bottleneck of the profit growth of tea industry. This study took Zhejiang Province as an example, and constructed mechanism models based on the industrial integration theory and coupling theory. The mechanism models were tea tour integration motivation, path integration, as well as integration benefits. Coupling function model was given in this study to investigate on the integration and interactive development of tea tourism in Zhejiang Province. It turned out that tea and tourism industries in Zhejiang province was in the phase of growth, while the development of tourism industry was slower than that of tea industry, and tea industry played a leading role. Obviously, the integration of tea industry and tourism industry was evolving from a disordered state to a coupling coordination state.
