Socialist market economy
The socialist market economy is seen by the Communist Party of China as an early stage in the development of socialism (this stage is variously called the "primary" or "preliminary" stage of socialism), where public ownership coexists alongside a diverse range of non-public forms of ownership. The Communist Party of China maintains that despite the co-existence of private capitalists and entrepreneurs with public and collective enterprise, China is not a capitalist country because the party retains control over the direction of the country, maintaining its course of socialist development. Proponents of this economic model distinguish it from market socialism as market socialists believe that economic planning is unattainable, undesirable or ineffective and thus view the market as an integral part of socialism whereas proponents of the socialist market economy view markets as a temporary phase in development of a fully planned economy.
Socialism with Chinese characteristics
The Communist Party of China still considers private ownership to be non-socialist. However, according to party theorists the existence and growth of private ownership does not necessarily undermine socialism and promote capitalism in China. It is argued that Karl Marx and Friedrich Engels never proposed the immediate abolishment of private ownership. According to Engel's book "Principles of Communism", the proletariat can only abolish private ownership when the necessary conditions have been met. In the phase before the abolishment of private ownership, Engels proposed progressive taxation, high inheritance taxes and compulsory bond purchases to restrict private property while using the competitive powers of state-owned enterprises to expand the public sector. Marx and Engels proposed similar measures in "The Communist Manifesto" in regards to advanced countries, but since China was economically undeveloped party theorists called for flexibility regarding the party's handling of private property. According to party theorist Liu Shuiyuan, the New Economic Policy program initiated by Soviet authorities in the aftermath of the war communism program is a good example of flexibility by socialist authorities.
