地铁运营不仅可以解决城市交通拥堵问题,还具有节省土地资源、节省能源,减少环境污染,拉动城市经济发展等特点,社会效益非常显著。但由于地铁运营作为重要的公益项目,具有建设投资巨大,运营成本高,票价收入低等特点,运营亏损通过地铁附属资源开发收入弥补后,仍有很大缺口, Subway operation not only can solve the problem of urban traffic congestion, but also has the characteristics of saving land resources, saving energy, reducing environmental pollution and boosting urban economic development. The social benefits are very significant. However, due to the huge investment in construction, high operation cost and low fare revenue, the operation of MTRC, as an important nonprofit project, still lags behind after the operating loss is made up by the revenue from the development of subsidiary resources of the MTRC.
