In recent years, the budget of public infrastructure is getting less due to the expanding of other budget. At this moment, promoting private participation in infrastructure projects can not only help continuing the construction of public infrastructure, satisfying people’s need and request for public infrastructure, provide more job openings and also stimulate economic growth when the taxation is limited. In addition to save government expenditure in construction stage, it also saves the operation and personnel expenses during the operation stage because the private sectors takes charge of it. Moreover, if the private investor operates the infrastructure, they will be more concerned about how to operate it well. Their creativity of building infrastructure can also help bring new life to unused space and avoid having completed public properties left to waste. To sum up, PPP can offer better service to people and avert government from wasting resources.
