This report uses the method of empirical research and case study to make a comprehensive analysis of the judicial documents of the court and finds that the growth rate of PPP cases shows a significant downward trend，with following characteristics that the proportion of cases tried by grassroots courts continues to rise，the proportion of cases applying civil procedure continues to rise，and the number of PPP cases in different regions of China is not evenly distributed. The application standard of the Judicial Interpretation on Administrative Agreement is not uniform in cases，which shows problems of insufficient reasoning and incomplete argumentation. The jurisdiction game between private enterprises and governments has extended from the PPP contract negotiation stage to the litigation stage，which makes the jurisdiction game more complicated. The invalidity of the arbitration clause in the administrative agreement provided by the judicial interpretation of Administrative Agreements has disrupted the civil procedure channel for the judicial review of the validity of the arbitration agreement，as well as has given both parties a way to confirm the invalidity of the arbitration agreement through the administrative procedure to a certain extent. It is necessary for courts to strengthen argumentation on the judgment of the legal nature of PPP agreements and the choice of litigation procedures in judicial judgements.
