Abstract
The purpose of this paper is two-fold: first to evaluate a certain public-private partnership (PPP) project implemented in the City of Yokohama, and through identfying factors causing differences of results, second, to suggest an effective way to implement PPP at a local level. Using the results of questionnairs answered by participating citizens together with case studies, 25 specific projects implemented by 18 ward offices of Yokohama City were evaluated on the basis of varied measurement criteria such as the purpose of the project as specified in the plan. Factors causing differences of results were analyzed on the basis of interviews of both citizens and public offices in charge of each project and the assessment of the actual facts for the projects — for example, whether budgets were contributed to citizens or not. It is concluded that the more decisively power and responsibility were shared between NPO and public offices, the more effective the PPP projects were. However, it was also made clear that in order for NPO to be able to participate effectively in PPP, they need further effort to gain trust and reliability to carry the decisive power and responsibility expected from the PPP framework.
