Public assistance to private schools means that the government encourages and helps private-invested schools to provide better educational services by providing funds, educational resources or policy support to private schools. This model conforms to the development trend of market economy and is also conducive to improving the quality of education.

The rise of public and private schools has effectively promoted educational equity. With the support of the government, private schools can provide better educational resources and teachers, thus providing more families with quality educational choices. This situation is more obvious in poor areas, and the investment of government funds can make private schools better serve poor families and vulnerable groups.

Public-aided private schools contribute to the innovation of educational mechanism. Private schools are more flexible in management, and can adjust teaching plans and increase courses more quickly to adapt to the rapid changes in social needs and students' needs. With the support of the government, private schools can also innovate in talent introduction and textbook development to promote the development of education.
