铁路建设与其他基础设施不同,不仅是因为其投资巨大,回报期长,还因为铁路的网络特征使其生产经营比一般的行业具有更为复杂的特征。但是,在铁路发展的初期,各国基本上都采取了相应的支持政策。比如疆域面积比较大的美国,在这方面的做法也许能给我国目前的铁路改革提供一些借鉴 Railway construction is different from other infrastructure not only because of its huge investment and long payback period, but also because its network characteristics make it more complicated than the average industry. However, in the early days of railway development, all countries basically adopted corresponding supportive policies. For example, the United States, with a relatively large territory area, may provide some reference to China’s current railway reform.
