建立一种公路经济分类的新方法——公路两类型我国公路有两种传统的分级方法:一种是行政分级法,把公路划分为国道、省道和县乡道路;另一种是技术分级法,把公路区分为高速公路和一、二、三、四级公路。这两种分级法无疑是必要的,长期实践证明也是正确的。但是,它们都没有能够体现出公路固有的本质属性即公路二重性。如果说这种状况在计划经济体制下尚且可行的话,那么,在社会主义市场经济条件下,仅有这两种分级法就显得很不适应了。因此,需要以公路二重性为基础,建立一种按照经济类型区分公路的新的分类方法,这就是把公路分作公益型公路和商品型公路两大类。公益型公路是以公益性服务为宗旨的公路。其基本特点是:建设投资来源于中 The establishment of a new method of highway economic classification - the two types of highway There are two traditional methods of grading our roads: one is the administrative classification method, the highway is divided into the national highway, provincial highway and county road; the other is the technical classification Law, the highway is divided into highways and one, two, three, four highway. These two grading methods are undoubtedly necessary, and long-term practice proves to be correct. However, none of them can reflect the intrinsic nature of the road, that is, the road duality. If this situation is still feasible under the planned economic system, then under the conditions of a socialist market economy, only the two grading laws seem to be inadequate. Therefore, it is necessary to establish a new classification method based on the duality of roads to differentiate the roads according to the type of economy. That is to say, the roads are classified into two types of public roads and commercial highways. Public highway is to public service for the purpose of the highway. Its basic characteristics are: construction investment comes from
