With the continuous growth of the demand for inter-regional personnel exchanges between modern social and economic development, high-speed railways, as a modern means of transportation that combines various high-tech, play an important role in meeting the high demand for mobility among regions and promoting social development. Among them, Shanghai-Kunming high-speed railway, as an important part of China’s high-speed railway network, deserves in-depth study. In this paper, the city quality is obtained by comprehensive evaluation of cities along the line by entropy method. The time distance is used to replace the spatial distance. The gravitational model of the city is optimized, and the gravitational change between cities along the line before and after the opening of the Shanghai-Kunming high-speed railway is more scientifically described. Finally, the paper proposes that the opening of the Shanghai-Kunming high-speed railway can effectively promote the economic development of cities along the line, especially the rapid rise of western cities.
