Public ownership is the foundation of China's socialist economic system. According to article 6 of the constitution of the People's Republic of China,"socialist public ownership, namely ownership by the whole people and collective ownership by the working people", the manifestation of public ownership in China is ownership by the whole people and collective ownership by the working people. However, the two forms of public ownership defined in the constitution of China have theoretical flaws and violate the spirit of basic jurisprudence. The legal form of public ownership should be state ownership.
