The National Transformation Programme (NTP) will elaborate upon Vision 2030, an 84-page document released in April by Deputy Crown Prince Mohammed bin Salman, 30, who is leading the reform charge.
At the heart of the Vision is a plan to float less than five percent of state oil firm Saudi Aramco on the stock market.
The proceeds would become part of the world's largest state investment fund, with USD 2 trillion in assets.
Profits from the investment fund would help economic diversification and provide an alternative to oil revenues that have fallen by about half since 2014.

The main economic coordinating body, the Council of Economic Affairs and Development chaired by Prince Mohammed, last night decided to submit the "final version" of the NTP to the cabinet for approval, the Saudi Press Agency said.
According to Vision 2030, the NTP relates to the government's role "in implementing the initiatives necessary for delivering on national priorities."
It said opportunities for partnering with the private sector were being looked at, "as well as innovative administrative and funding approaches. We are detailing specific initiatives that have clear performance indicators."
Saudi Arabia is one of the world's most conservative societies, but more than half of its citizen population is younger than 25.
