Public-private partnership (PPP) is a funding model for a public infrastructure project. The public partner is represented by the government at a local, state and/or national level. The private partner can be a privately-owned business, public corporation or consortium of businesses with a specific area of expertise.
Under this mode, private enterprises and private capital are encouraged to cooperate with
the government and participate in the construction of public infrastructure.
PPP has been widely used in many B&R countries, having the realistic foundation to adopt the PPP mode. PPP can help solve the financing gap of specific infrastructure projects, and improve the quality and efficiency of public services by rebuilding the professional private institutions and innovating the return mechanism of infrastructure projects.
