The total number of PPP cases in China is increasing continuously，but the growth rate of cases has decreased since 2017. PPP cases are mainly heard by grassroots courts and mainly subject to civil procedures. The industries with the most PPP disputes are municipal engineering and transportation，and the region with the most cases is Henan Province. In administrative litigation cases that enter substantive adjudication，the government party loses at close to half. The Judicial Interpretation on Administrative Agreement does not completely block the arbitration channels for PPP disputes，and courts apply the “substantive review” approach to specific judicial practices，so as to maintain an attitude in favor of arbitration. However，Article 26 of the Judicial Interpretation on the Administrative Agreement causes great uncertainties in the approaches to resolve PPP disputes，constrains the space for private investors to resolve PPP disputes through arbitration and adversely affects the investment confidence of private investors. With regards to specific PPP contract disputes，judicial organs should apply the “substantive review” approach to allow the PPP disputes to be resolved through civil proceedings or arbitration proceedings.
