Abstract:Perceived justice of the private has been identified as a key factor of cooperation in PPP projects. Data collected through document analysis and qualitative interviews were coded using the software of Nvivo 10. Dimensions of perceived justice of the private in PPP projects were explored based on grounded theory. Three sub-core categories were found, including distribution justice, procedural justice and interactive justice. Furthermore, the conceptual model of perceived justice of the private in PPP projects was presented by comparing practice with research results and analyzing their relations and differences. Finally, Management suggestions given to the public based on conclusion above are as follows: ①the obligation should be fulfilled in accordance with the contract strictly in order to prevent government intervening PPP projects and shirking responsibility; ②the initial contract should be fair and a reference point during every renegotiation; ③the spirit of contract should be strengthened, thought should be transformed and the relationship with the private should be established equally.
