The Cost-Benefit Analysis In The Government Investment Projects Feasibility Study Applied Research

The cost-benefit analysis is an important means of scientific project decisions, a main method of engineering construction project investment risk analysis, and an important basis for investment decision.The core of the cost-benefit analysis is to examine the costs and benefits of the analysis of engineering construction investment projects, include the financial cost-benefit analysis and economic cost-benefit analysis.This article from home and abroad to carry out engineering construction project cost-benefit analysis of the status quo, the concept herein and government investment projects, the range is defined, expounded the basic characteristics of the government investment projects.The article focuses on the application of cost-benefit analysis in government investment project feasibility, Guangxi Leye to Baise Expressway project as the actual case to be a specific analysis. After analysis, Guangxi Leye to Baise Expressway project is feasible, but still need to take some measures to increase social benefits,because the highway as the relationship between the public interests of the government investment projects, should guarantee the basic financial gain through a variety of channels to improve its social benefits, for example, take charges as low as possible. Meanwhile, the combination of the actual case, pointed out that the cost-benefit analysis in the practical application of inadequacies, such as difficult to give an accurate effective monetary value, measurement of the impact of environmental resources is difficult. Finally, The article point out the problem of cost-benefit analysis and the propose recommendations for improvement, improve the indirect benefit evaluation and social evaluation,establish the holographic project decision-making information systems, increase the evaluation method of the highway expansion project, etc.
