Research On PPP Project Tracking Audit

The PPP(Public-Private Partnership)model is a new type of cooperation model formed between the government's public sector and the private sector.The government can use the capital advantages of the private sector to alleviate financial pressures and risks,and improve or solve the insufficiency of public products and services.At present,the PPP model has been extensively developed in China,however,there are various problems in the actual application of the PPP projects.In order to ensure the standardized and efficient application of the PPP projects,audit is essential.Given that the PPP model has the characteristics of large investment amount,multiple participants,and long construction period,the tracking audit is more suitable for the PPP project than the engineering settlement audit.However,the tracking audit of PPP projects in China started late,and the theoretical basis and practical experience are insufficient.As a result,the tracking audit of the PPP projects cannot fully play the role of early warning and control of risks in actual implementation,and cannot guarantee the beneficial implementation of the PPP projects.Therefore,it is crucial to study the tracking audit of PPP projects and put forward effective suggestions for improvement.This research first analyzed the concept and connotation of the PPP model and tracking audit through literature research,and then elaborates the theoretical basis of PPP project tracking audit.The necessity of PPP project tracking audit and the operation of the PPP project tracking audit was explained.Then,in terms of investment scale and construction content,the representative and typical G rail transit engineering PPP project served as a research case,and the whole-process tracking audit was conducted.Firstly,the overview and research progress of the G project were introduced and the tracking audit plan for the G project was formulated.Next,for the identification,preparation,procurement,execution and handover stage of the G project,the tracking audit evaluation index systems were created and the tracking audit was conducted,then provided suggestions for the problems found in the audit.Finally,the problems and causes of the tracking audit for the G project were analyzed,and effective suggestions were put forward based on the actual situation.This study showed that several problems such as imperfect audit objectives and content,tracking audit procedures are not implemented standardly,audit results are not in place and unreasonable configuration of the audit team are existed in the current PPP project tracking audit.The problems in the PPP project tracking audit were mainly caused by the difficulty of PPP project tracking audit,the deficiency of relevant laws and regulations,the imperfect PPP project tracking audit system,and the insufficient professional quality of the PPP project tracking audit team.Therefore,in order to strengthen the function of risk warning and control and ensure the effective implementation of the PPP projects,laws and regulations on PPP project tracking audits should be improved,standardized PPP project tracking audit systems should be formulated,and the professional allocation of audit team should be diversified and the professional knowledge system of auditors should be continuously improved.
