摘要
本文从航运效益计算应遵循的原则、运量分类、效益计算三方面对黄河干流航运效益的计算方法进行了探讨。指出效益计算中所采用的运量、费用都是预测值,会导致效益计算具有不确定性,因此只能采用不确定性分析的方法对运量、运价等进行敏感性分析,求出在一定条件下的效益值,供决策时参考。
The calculating methods of shipping benefits in the main waterway of Yellow River are investigated from three aspects, including the principle, classification of traffic and calculation of benefits. It is evident that, owing to the traditional method in calculating the shipping benefits being based on the predicted values of volume of traffic and expenses, the calculated resulls might be quite indeterminate. This paper suggests that it is more reasonable to use a method of indeterminacy analysis on the calculation of volume of traffic and expenses,so as to make the calculated results of shipping benefits more reliable, with which it may be of use for reference to the policy-ma-kers.
