It is a form of public ownership economy that has gradually evolved under the market economy environment. It can make up for some shortcomings of the state-owned economy and provide a solid foundation for economic development.

in addition to the above-mentioned economic forms, the public economy is also an important form of public ownership economy. The public economy is an economic form composed of service industry, public facilities and infrastructure construction funded or directly participated by the government.

In addition, in the economic development of China, many new forms of public ownership economy have emerged, such as socialized public ownership, fund public ownership, mixed ownership reform, supporting and promoting non-public ownership economy and so on. These new forms, while gradually expanding and developing, have also enriched the connotation and extension of the public ownership economy and injected new vitality and dividends into the economic development of China.
