The input and output efficiency of subway project is a major source of profit for subway construction enterprises. In order to improve the input-output efficiency, increase the benefits of subway construction enterprises, it is necessary to research the subway construction cost mechanism. In this paper, based on the basic concepts of cost, managing and controlling effect and mechanism, through the literature review and research interview, the key factors affecting the subway construction cost are identified. Based on this, the conceptual model of the mechanism of subway construction cost is constructed, and the research hypotheses are put forward, and the structural equation model is used to do empirical research to show that the factors such as construction management, technology, environment, etc. have significant impact on the cost control of subway construction, and it reveals the mechanism of subway engineering cost, providing theoretical basis and practical guidance for improving the level and effect of cost control.
