随着近年来公路、航空、水运等交通运输工具的迅速崛起以及铁路运输发展的相对滞后,对铁路客运、货运方面的“挤兑”效应非常明显。加之行业上市公司的稀缺性,也使市场淡化了对铁路运输行业的关注。在此我们本着自上而下研究和深入挖掘子行业的原则努力寻找被市场“所遗忘的角落”,对曾被喻为“铁老大”的铁路运输行业进行重新审视。 With the rapid rise of transportation means such as highways, airlines and waterways in recent years and the relatively lagging development of railway transportation, the effect of “run-off” on railway passenger transport and freight transport is very obvious. Coupled with the scarcity of listed companies in the industry, but also the market played down the concerns of the railway transport industry. Here we strive to find the “forgotten corner” of the market in the spirit of top-down research and in-depth mining of sub-industries, and re-examine the railway transportation industry that has been dubbed the “iron boss.”
