Sustainable public-private partnerships: Balancing the multi-actor ecosystem and societal requirements

摘要

The funding gap of public infrastructure networks (roads,railways,ports,electricity,and energy lines) can be solved partly by introducing private capital for investments,i.e.,public-private partnerships (PPP).This paper introduces an integrated model of a PPP project and investigates its implications on PPP policies and strategies regarding appropriate project appraisal and selection.The model has different resolution levels,namely,project level,business ecosystem level,and market and societal levels.The integrated model suggests that investing in merely financially viable projects is insufficient to realize economically and socially sustainable and acceptable projects.
