The Marxist theory of social reproduction discusses the supply of products and the conditions of their realization in social reproduction.It provides guiding ideas for studying the supply and realization of media products.The productive labor of material media products and media services can be included in the total social product.The condition for the simple reproduction of media products is that the sum of the value of material media production and media service production produced in the first category must equal the value of production in the second category.There are several prerequisites for the expanded reproduction of media products:There must be the accumulation of each category or product in the production process of a cycle.The total supply of media must exceed the total demand.Simultaneously,supply must exceed demand for both the media means of production and the media means of subsistence.Finally,supply must exceed demand for media products in a single category.The necessary conditions for the expanded reproduction of media products are to ensure that the value and use value of the total social product are compensated and that the production of means of production and the production of means of consumption are balanced on an incremental scale.
