Factors Underpinning the Successful Return of Public-Private Partnership Projects to Public Authority: Assessing the Critical Success Factors of the Transfer Phase of Chinese Water Projects

In China, public-private partnership (PPP) projects consist of six phases, from inception to completion. In the final phase, known as the transfer phase (TP), the project assets are transferred back to the government, and the project is effectively closed out. Although success factors (SF) covering the earlier phases of PPPs have been well-documented, little is known about the effective execution of the TP in China. The main reason is that PPPs are a relatively new phenomenon, with few having reached the end of their life cycle, although this is happening now. Consequently, the determination of critical success factors (CSFs) in the TP is of great interest. This study aims to identify those CSFs that are most impactful to the success of the TP. A total of 23 process factors, arranged in four factor groups, are taken from an earlier study. These factors were presented to China's water PPP project experts in an online questionnaire, with 52 valid responses returned. Of the 23 process factors, 22 were revealed to be statistically critical to the success of the TP, which were identified as critical transfer success factors (CTSFs). The top five CTSFs are (1) contract system, (2) infrastructure, (3) transferred assets, (4) transfer acceptance criteria, and (5) overhaul information. The identification of the relative criticality of CTSFs and, in particular, the identification of the leading factors, can be expected to support the government and contractor entities in effecting the smooth transfer of many Chinese PPP water projects approaching maturity.
