Research On Economic Evaluation Of New Landing Interchange Based On The Inconsistence Of Investment Operating Subjects

In recent years,local governments along expressways have put forward the requirement of additional interchange.Because of the inconsistency between the investment subject and the operation subject of the new expressway interchange project,that is,the local government investment and the expressway company toll management;at the same time,the new expressway interchange project does not produce benefits alone,that is,although the toll station is located in the interchange,the toll charged is carried by the expressway.In this way,it is not suitable to adopt the original ideas and methods of economic evaluation of expressway construction projects.Therefore,in view of the traffic economic characteristics of such projects,it is of great significance to study the economic evaluation of new expressway interchange projects under inconsistent investment/operation subjects.Through consulting a large number of references at home and abroad,this thesis analyses the traffic economic characteristics of highway interchange projects with inconsistent investment and operation subjects,summarizes the shortcomings and limitations of existing economic evaluation methods for highway interchange projects,studies the effectiveness of incremental analysis method in economic evaluation of New Interchange projects,and the application of system dynamics in the evaluation of New Interchange projects.Feasibility of eliminating incremental induction benefits.On this basis,firstly,the SP(Stated Preference)-gravity model is established to solve the transfer traffic volume and calculate the incremental traffic flow.Secondly,the incremental output benefit based on the incremental traffic flow calculation and the incremental induced benefit based on the system dynamics model are proposed by identifying the incremental national economic benefit cost.The improved shadow price of incremental economic cost during the construction period is studied.Lattice calculation method and improved calculation method of new indirect economic cost of heterodyne cost;then,through identification of incremental financial benefit cost,the operation financial change under the condition of project or not is analyzed,the incremental financial benefit model is constructed,and the calculation method of incremental financial cost is put forward;finally,through an example of a highway newly added landing interchange project,the investment-based calculation method is carried out.The evaluation of national economy from the perspective of subject and the calculation of financial evaluation based on the perspective of operation subject.Through the study of the main related theoretical knowledge,this thesis provides a theoretical basis for the economic evaluation of the pre-investment decision-making stage of new expressway interchange projects.These theories,models and methods have certain theoretical and practical value,and can be used for reference for the future economic evaluation of similar projects.
