Please give an example to talk about the basis of establishing a basic economic system with public ownership as the main body and multiple ownership economies developing together in China.

For this question, if you want to combine examples, it is a long answer. Let me talk about the main points: the main basis for China to establish a "basic economic system with public ownership as the main body and multiple ownership economies developing together" is:

First, China is a socialist country and must adhere to the socialist economic system based on public ownership;

Second, China is in the primary stage of socialism and needs to develop a diversified ownership economy under the condition that public ownership is the main body;

Third, all forms of ownership that conform to the "three benefits" can and should be used to serve socialism.
