Study on Sustainable Development Strategy of Subway in Medium-sized Cities in China: Case Study of Fujian Cities

Abstract

The development of the subway is closely related to the urban economy in China, and it is also a sign of the development of urban modernization. With sustainable transportation development becoming a global issue, the construction of medium-sized urban subways is limited by the economic volume and is often in the trade-off between construction speed and financial burden. This paper takes the subway cities of Fujian Province -Fuzhou and Xiamen as the research object and analyzes the relative positions of the metros of the two metropolitan areas in 38 metro cities in China. The result of linear regression analysis shows that Fuzhou's progress is slightly conservative, while Xiamen is slightly ahead. There is still space for improvement in the carrying intensity of the subways in the two cities. Comparing the relationship between subway construction and economic growth in medium-sized cities, there is still obvious room for development in subway construction in the two cities. During the research process, actual investigations were conducted to formulate corresponding improvement strategies and suggestions for the operation problems of the two cities for reference by the urban management departments.
