Treasurer Mike Baird says a new report on the next stage of Asia's economic boom is good news for NSW.

He says the report by Deloitte Access Economics shows NSW will be a major winner from a predicted resurgence in tourism, international education, wealth management, gas and agribusiness.

All up the boom is forecast to be worth an extra $250 billion nationally over the next 20 years.

"The NSW Government is very encouraged by this report, which suggests Asia's impact on Australia is changing in ways that will really play to NSW's economic strengths," Mr Baird said in a statement.

"All the signs indicate that NSW will reap the benefits in the next boom phase, as NSW has the biggest share in the five upcoming sectors than any other state."
