What makes public-private partnerships work? Survey research into the outcomes and the quality of cooperation in PPPs
基于荷兰144位PPP项目参与者的调查数据，研究发现信任和管理活动与项目绩效显著相关，且信任有助于良好的合作过程。
Public–private partnerships (PPPs) are often regarded as the solution for time and budget overruns in large infrastructural projects, but not all are successful. This raises the question of what really makes PPPs work. Focusing on the role of relational aspects, this article examines the degree to which trust and managerial activities correlate to the perceived performance and cooperation process in PPP projects. A multilevel analysis of survey data from 144 respondents involved in Dutch PPP projects shows that both trust and management correlate significantly to the perceived performance of these projects. Moreover, trust is associated with a good cooperation process.
