The labor productivity problem of media users using media digital platforms for data production is a new problem of Marxist political economy in the digital economy era. Returning to the theoretical track of Marxist political economy, the analysis of the problem from the three perspectives of the contradiction of the capital general formula, commodity of information products and the total process of commodity production shows that the digital labor of media users is productive. The non-employment change in the productivity of digital labor for media users is a new variation of Marx's classic regulations on the productivity of workers' labor in the era of digital economy, which also reflects that the basic contradictions of capitalism are still using irresistible forces to promote a new reconciliation of communist-oriented production relations within capitalism.
