两年以前,高铁在民航还是个很前卫的话题,谈论高铁的挑战常常被认为是杞人忧天。那时候对高铁的认识是模糊的,感受是不真切的,论证也只是理论性的。但现在高铁已经实实在在运行起来了,距离初步建成高铁网络的日子日益临近。必须认识到,高铁对民航的挑战不仅是战略性、颠覆性的,而且也十分紧迫。 Two years ago, the high-speed rail was still a very avant-garde topic in civil aviation. The challenge of high-speed rail is often regarded as unfounded. At that time, the understanding of high-speed rail was vague, the feeling was not true, and the argument was only theoretical. Now that the high-speed rail has actually started to operate, the days from the initial establishment of a high-speed rail network are coming nearer. It must be recognized that the challenge of high-speed rail to civil aviation is not only strategic but also disruptive and urgent.
