Research On National Economic Evaluation Of High Speed Railway Construction Projects

The realization of medium and long-term railway network planning in China will inevitably lead to the construction of new railways.Whether the completion of railway construction projects will meet the expected benefits of the national economy for the project,and whether the benefits can exceed the resources input of the national economy for the project are a series of issues that project decision makers are concerned about,and more importantly,the national economy.The construction must answer the question.Therefore,in the early stage of construction,it is particularly important to evaluate the national economy of railway construction projects.National economic evaluation is an indispensable step in economic evaluation of railway construction projects.To evaluate railway construction projects,we must conduct all-round,objective and scientific economic evaluation of the projects under construction from the perspective of national economic development.The comprehensive benefits that the project can bring.Therefore,it is very important to conduct economic evaluation of railway construction projects.National economic evaluation is a very important part of the economic eval-uation of railway construction projects.This paper regards civil engineering fees,locomotive vehicle purchase costs,shadow wages,operating expenses,loan inte-rest as the cost of railway construction projects,and operating income,passenger time savings,To promote the development benefits of related industries as the b-enefits of the project,use shadow prices and social discount rates to adjust th-ese costs and benefits accordingly.Finally,the financial price is transformed into the shadow price in the national economic evaluation.According to the price,the three national economic evaluation indicators,such as the economic net pres-ent value,the economic internal rate of return,and the investment recovery peri-od,can be calculated according to the evaluation index.The situation determines the feasibility of the railway hypothetical project and makes corresponding deci-sions.In the end,taking the Wuhan-Guangzhou Passenger Transport Line as an example,the national economic evaluation system of the construction project est-ablished in this paper is used to evaluate the national economy and verify the r-ationality of the system.
