Analysis of the Chinese model and the socialist market economy by the economists Julan Du and Chenggang Xu finds that the contemporary economic system of the People's Republic of China represents a state capitalist system as opposed to a market socialist system. The reason for this categorization is the existence of financial markets in the Chinese economic system, which are absent in the market socialist literature and in the classic models of market socialism; and that state profits are retained by enterprises rather than being equitably distributed among the population in a basic income/social dividend or similar scheme, which are major features in the market socialist literature. They conclude that China is neither a form of market socialism nor a stable form of capitalism.
