At present，China's economy is entering an economic shift period. From the international experience，this period will be a crucial period for the development of China's tourism industry from quantity to quality. For China's tourism industry，from high-speed to medium-speed，economic shifts brings new opportunities for tourism development. On the other hand，it also makes the old growth model unsustainable. The new growth mode is still restricted by the old model. China's tourism industry should play a greater role in the national economic system and the world tourism pattern from the big tourist countries to the tourism powers. It is necessary to build a high-deep industry in a medium-speed environment，which is in urgent need of reform and innovation.
