Research On Analysis And Practice For Urban Rail Transit Project Benefit

Having quasi-public characters,urban rail transit projects are main basic infrastructure of national economy and are very important to solve traffic jam in cities and to realize sustainable development.Urban rail transit projects have prominent both social and economical benefit,and benefit analysis has key effect on the scientific decision making of these projects.For now,financial appraisal,national economic appraisal and social appraisal are the main methods on the benefits evaluation of urban rail transit projects,which have different theoretic basises,objects and effects.However,as one-factor index method, they can not integrate the economic benefits and social benefits and are prone to be affected by decision-makers.As an important basic facility in national economy,urban rail transit projects are effective way to solve the transit congestion and to achieve sustainable development in big cities.Since these projects have quasi-public characters with both considerable economic and social benefit,the scientific benefit analysis have fundamental significance to the urban rail transit projects.This dissertation takes urban rail transit projects as research object,and takes benefit as masterstroke to focus on benefit forming mechanism,benefit analysis index system and authority weight of benefit datas.Therefore,a new thought of analysis on project benefit could be provided.To research problems of urban rail transit projects benefit,the status quo and future tendency of urban rail transit industry should be analyzed(Chapt 2).By the end of year 2006,the number of built urban rail transit line was 630 kilometers.Basing on the systematic analysis of macroeconomic,industry policy and legal system,and taking the speed up tendency of urbanization and the public transport priority strategy,the dissertation expects the number to be 2000-2500 kilometers by year 2020.Based on the analysis on content pointed above,this dissertation researched the souce mechanism and explicit charactors(Chapt 3).Urban rail transit projects are quasi-public products;it has external and scale economic characters;its benefits are very extensive such as saving energy,resource and passengers' time,improving economy,working rate and real estate value,and reducing investment pressure on ground public transportation and city pollution.And it can be mainly divided into economic benefits and social benefits.Using the basic principle and method of project comprehensive evaluation,and taking the urban rail transit project as a particular research target category,the dissertation has set up a series of index system to reflect the technological,economical, social,and other kinds of benefits from multi-angles,multi-levels and a broad scope, hence to form a overall index system of benefit analysis for urban rail transit project (Chapt 4).Having described the urban rail transit project in detail from different levels and angles,the index system is hierarchical,quantitative and comprehensive.The benefit analysises of urban rail transit project existing are mostly focusing on individual benefit factor.This dissertation basing on urban rail transit project source mechanism,and the overall index system of benefit analysis for urban rail transit project, provided the model of urban rail transit project benefit analysis basing on rough set(Chapt 5).Through knowledge expression of urban rail transit project benefit factors, the information decision table of urban rail transit project benefit could be formed. Hence,the authority weights confirming model basing on rough set could be established. In addition,the demonstration analysis aiming at 8 urban rail transit projects which have been started working recently is provided.The results of demonstration indicate that the benefit analysis basing on rough set is having more advantages than traditional individual factor index analysis.Taking the multidimensional combination weight analysis basing on rough set,this dissertation explains the financing methods selection of urban rail transit project basing on benefit analysis(Chapt 6).The practices,types and characters of urban rail transit projects financing are summarized,posting the relationship between results of analysis on benefit weights and financing schemes selecting.Therefore,a feasible evaluation means for financing design could be provided.
