High-quality development has become the theme of China's economic and social development in the new era. Based on the review of the research on the integrated development of culture and tourism, the article proposes that accelerated integration development should be promoted under the requirements of high-quality development. Based on the theoretical interpretation of highquality development, the article analyzes the current achievements and problems in the integration of cultural and tourism development, and reveals the guiding significance of high-quality development for the deep integration of cultural and tourism development. The article argues that the internal motivations to promote deep integration consist of production integration, technical support, and industrial upgrading. The external motivations are reflected in five aspects: consumer demand, system sharing, creative economy, system and policy. External factors promote internal factors. In the end, the article summarizes the driving mechanism of the high-level development perspective and the deep integration of travel and tourism into the four-fold progressive mechanism of “penetration, crossover-reorganization, promotion-innovation, and drive-multiple collaboration”.
