在改革的大潮中,各种大型经济项目不断孕育、诞生。这些项目在怀胎前都必须经过“可行性研究医生”把脉论证,写出研究报告,评出最佳可行性方案,方可立项实施。大凡在评估可行性研究方案时,无论采取何种评估手段和方法,都要遵循评估的基本原则。概括地说,就是要以“五.三”为原则:一是空间的三行情——国情、地情和本情。一个项目是否可行,先得从国情出发,紧紧抓住方向;接着再看地情,立于基本;最后审视本情,有的放矢,才能站稳脚跟。二是时序的三阶段——项目的过去、现在和将来的情 In the tide of reform, all kinds of large-scale economic projects are constantly being born and born. These projects must be preceded by “Feasibility Study Doctors” to prove the pulse of the pulse and write down the research report prior to pregnancy, and evaluate the best feasible solution before implementing the project. In the assessment of feasibility study programs, no matter what kind of assessment methods and methods, should follow the basic principles of assessment. In a nutshell, we should adopt the principle of “five, three,” as follows: First, the three quotations of space - national conditions, earth conditions and nature.
