随着经济的快速增长,运输量的持续扩大,交通运输的社会成本也随之越来越大,其主要原因是交通运输的发展会占用土地、消耗大量资源,产生噪声、污染大气环境等一系列环境问题,同时还可能造成一系列交通拥挤,甚至有可能引发交通事故等,间接地加大了社会成本。不仅如此,油价上涨进一步压缩交通运输企业的生存空间,人们对节能降耗的关注度也越来越高。 With the rapid economic growth and continuous expansion of transportation volume, the social costs of transportation have also become larger and larger. The main reason is that transport development occupies land, consumes a lot of resources, generates noise and pollutes the atmosphere Series of environmental problems, but also may cause a series of traffic congestion, and may even lead to traffic accidents, indirectly increased social costs. Not only that, oil prices further reduce the living space for transportation enterprises, people are more and more concerned about the energy saving.
