What is the role of the private sector in financing and developing public sector projects pls give sites?

Answer 1

The private sector, which includes big business, is taxed and finances the entire public sector.

Microsoft pays huge taxes to the government each year which is the public sector. Also Bill Gates "gives" money to the charity which is also the public sector.

The private sector also buys government construction bonds called "municipal bonds" which fund public sector improvements like roads and bridges.
