Marx's theory on the division of social formation provides theoretical basis for the study of the development stages of capitalism. According to the stage qualitative change of the means of production in the whole quantitative change, capitalism can be divided into five stages: individual capitalism, collective capitalism, aggregative capitalism, national capitalism and international capitalism. Based on the partial qualitative change of the means of production in the whole quantitative change, capitalism can be separated into three stages: feudal capitalism, capitalism proper and social capitalism.
