Improved Research On The Whole-process Follow-up Auditing Based On A National Road Reconstruction And Expansion PPP Project

The supply-side structural reform in China is constantly deepening.In order to alleviate the local government's financial constraints and debt pressure,private capital has been widely entered into the field of infrastructure and public services and entered a period of rapid development under the encouragement of national policies and laws.However,the PPP management presents a state with a large number of project library but less implementation,and the phenomenon of pan-PPP is serious.The review of PPP projects is mostly in the form of a lack of comprehensive and effective auditing and supervision,which seriously affects the implementation of central policies.This paper conducts case studies on the A national road reconstruction and expansion project.It has important theoretical and practical significance for improving the life cycle management level of road construction PPP projects,improving the content,procedures and methods of PPP projects audit and promoting the healthy and orderly development of Public-Private Partnerships.Based on the principal-agent theory,stakeholder theory,value-for-money theory,risk-oriented audit theory,and life cycle project theory,this paper analyzes the control objectives and key control points of all stages of the whole process tracking audit based on policies,regulations,auditing standards and system regulations.Combined with the particularity of audit risk of PPP project,this paper analyzes the legality,compliance and integrity of the audit process of A National Road Reconstruction and Expansion Project,and believes that the audit team has the advantages of familiarizing with policies and regulations,attaching importance to communication,properly using expert advice,and actively organizing pre-existing training.But there are also problems such as unreasonable auditor structure,inaccurate point of intervention in the procurement phase,inadequate contract management audit,weak audit independence,and inappropriate assessment of audit risk.Therefore,considering the difference between PPP project audit and traditional engineering project audit,in order to comprehensively guarantee the effectiveness of PPP project audit supervision,at the national level,the PPP project supervision environment should be improved from three aspects: laws and regulations,competent department responsibility and audit organization;The audit team should grasp the intervention time and technical methods of tracking audit based on the project decomposition perspective and national governance perspective;clarify the audit monitoring points and contents of each stage for the whole life cycle of the project;and it is necessary to improve the quality of auditors and pay attention to the use of risk-oriented auditing.
