A Priority in Land Supply for Sustainable Transportation of Chinese Cities: An Empirical Study from Perception, Discrimination, Linkage to Decision

With the rapid development of China’s economy, alleviating the shortage of land resources has become a significant challenge. Transportation infrastructure is a channel connecting cities, which carries the flow of population and material circulation. The efficient allocation of land used for transportation is closely related to production and life. By investigating the main factors affecting the priority of the supply of land used for transportation, this paper evaluates the transportation condition of all cities in China from five aspects: dominance, dependence, coordination, accessibility, and land demand for transportation. Furthermore, this paper constructs a multi-objective decision support system for land supply, which aims to find out which cities are in urgent need of the supply of land for transportation and what types of transportation infrastructure need to be focused on. The results of this paper show that most of the cities with high land supply priority are non-provincial capital cities and are important growth poles of regional economic development. The construction of a comprehensive transportation system is the short-term goal of these cities. Most cities with low land supply priority are sparsely populated, in good ecological condition, and far away from the core areas of economic development. The preferred transportation mode of these cities is generally land transportation. The main contribution of this paper is to provide a comprehensive decision support system for the land management department to determine land supply priorities and achieve the sustainable use of land.
