Research On Auditing Supervision Mechanism Adapt To PPP Project Mode

On September 25, 2014, the Ministry of Finance promulgated the ^Notice on Promoting the Use of Government and Social Capital Cooperation Modds,5, and proposed the practical significance of fully understanding and implementing the PPP model, actively implementing the preliminary work of the PPP model, and accelerating the construction of a An institutional system that facilitates the development of the PPP model. Under the realistic background of China!s current supply-side reform and mixed ownership, combined with the successful experience of foreign countries, actively promoting the PPP model is an important way for the Chinese government to transform its economic model. As an important national infrastructure, urbanization construction requires huge financial support. Through the PPP model, it can actively attract social capital, ease the government's financial capital pressure, and diversify investment risks.Compared with the traditional government investment project construction type,the PPP project model has a complicated operation process, with many participants, long cycle, high risk and uncertain cost recovery. Correspondingly, the audit methods and methods of traditional engineering projects cannot completely copy PPP projects, and the audit mode also needs to be different in audit focus, audit content, and auditing methods (Sun Lingzhi, 2016). Based on this background, this paper intends to conduct a case study in conjunction with the L County Cultural Center project to explore how the audit supervision mechanism under the PPP project model can be optimized.First of all, this paper summarizes the characteristics of current PPP models at home and abroad, and reviews the literature on PPP theory and audit mechanism, and proposes the inadequacies of theoretical research.Then, based on the theoretical research of principal-agent theory, the article designs the audit supervision mechanism of PPP project, proposes the optimization plan of the audit supervision mechanism of the six stages of PPP project, and analyzes the audit purpose, audit subject and key risk points of audit at each stage.Finally, combined with the L County Cultural Center project to conduct case studies,analyze the four stages of the audited subject, audit content, audit findings and causes.The project audit mechanism was evaluated, its highlights and defects were analyzed,and corresponding optimization suggestions were proposed. According to the problems found in the audit, the focus of follow-up audit is discussed.For China, the PPP project has not been practiced for a long time, and the laws,regulations and policies are still not perfect.Only in practice will new problems be gradually discovered and solutions to new problems will be explored.This paper,through case studies,hopes to give PPP projects.Audit supervision provides a reference.
