在严格的假设条件下,以公共经济学的基本理论为依据,建立了适当的数学模型。对模型进行数理分析的结果是,最优的公路投资策略是公共资金和私人资金投入到公路资产中所能获得的国民经济产出增量等于两者机会成本的合计,并提出了相对简便可行的计算方法。根据这一成果,进一步指出公路收费政策将经历3个阶段,即收费公路的大发展阶段、公路收费政策的调整阶段和公路收费政策逐步退出阶段。最后对中国公路收费政策的发展方向进行了判断。
Under strict assumptions, based on the basic theory of public economics, an appropriate mathematical model was established. Mathematical analysis of the model results show that the optimal highway investment strategy is the sum of the incremental economic output that the public and private funds input into the highway assets equals the opportunity cost of the two and puts forward a relatively simple and feasible The calculation method. According to this result, it is further pointed out that the highway toll policy will go through three stages, namely, the great development stage of toll road, the phase of adjustment of highway toll policy and the gradual withdrawal of highway toll policy. Finally, the direction of the development of China’s highway toll policy was judged.
