Rethinking the role of private capital in infrastructure PPPs: the experience of Ontario, Canada
研究了加拿大安大略省减少公私合作项目中长期私人资本后的效果，发现这并未损害项目绩效，反而为政府节省了成本，表明私人资本只是实现物有所值的工具之一。
Private capital has become a significant feature of infrastructure public–private partnerships (PPPs) on the premise that it incentivizes diligent risk management among private partners. This paper evaluates this claim by examining the PPP programme in Ontario, Canada, where the amount of long-term private capital in PPPs has been reduced. The paper shows that decreasing the amount of private capital after construction does not undermine performance, while producing cost savings for governments. This was achieved by deploying sophisticated procurement and monitoring strategies. These findings suggest that private capital is one of several tools available to achieve positive value for money in PPPs.
