The development results oriented performance evaluation research for public project at home and abroad is still in its infancy. In accordance with the designing and monitoring framework of public project performance management with the orientation of development results and on the basis of fuzzy neural network theoretical model, this paper attempts to construct performance evaluation model for public projects with reason, method, program, investment, activity as neural network input and the goals of the project, effectiveness, impact, outcome, yielding as output, thus providing theoretical guidance for the performance evaluation of public projects.
