| Output effectiveness is very important for investors during the course of investment and operation of projects. In our country, good effectiveness has been achieved in some projects of transportation infrastructural investments. However, some investment effectiveness is still not satisfied by us. Among the reasons, besides the factors of system, legality and law enforcement, unscientific and randomness in economic evaluation are also very important. The insufficiency of assessment basis, multiple counting of benefit and random selection of assessment factors result to the economic evaluation is only a kind of form. For instance, some investment projects are constrained by the market and the effectiveness and cost are easy to be measured by currency. However, most of the transportation infrastructural investment projects are named as "serving to the publics" and most of their efficiency is intangible, which offers reasons for the randomness of project decision-making and raise the possibility of waste. So it is necessary to conduct a systemic and overall research on the content and method of economic evaluation. The subjects researched in this thesis mainly are transportation infrastructural investment projects, but the principles and methods included in this thesis are also suitable for other investment projects, especially for those projects invested by the government or with high public welfare. In the thesis, the author has made induction, summary and research method on relevant issues and economic evaluation of transportation infrastructural investment projects, and also successively makes a depth research to financial evaluation, national economic evaluation, uncertainty analysis and overall evaluation methods in accordance with the contents of economic evaluation. The purpose of this thesis is to perfect the early stage work and economic evaluation theory of investment projects, thus to realize scientific, standardized and systemic decision-making for investment. |
