Abstract: In the transformation of digital technology into productivity, remarkable stratification can be found in social reproduction. It involves the stratification between the abstract and the concrete dimension of productivity, between controllers and the controlled regarding the means of production, and between the digital industry and traditional industries. Stratification also exists in the competition relations embedded in the digital industry, and in the polarized employment structure. The stratification of social reproduction represents a new way of capital accumulation. It is accompanied by possible challenges such as the technological monopoly, the crossfield expansion of capital's power, wealth polarization, and the weakened economic foundation of middleincome groups. Considering the impact and challenges of social reproduction stratification, and the mission of solidly advancing common prosperity in China, this paper takes into account both international and domestic environments and discusses the implications of social reproduction stratification for future economic development. 

Key words: digital technology, social reproduction stratification, capital accumulation, monopoly, middleincome group

摘要： 数字技术在向生产力转化过程中，社会再生产表现出明显的分层趋势，表现在：生产力抽象与具象的分层；生产资料的控制级与受支配级分层；数字产业与传统产业分层；数字产业内部嵌套竞争关系分层；以及两极化的就业结构分层。社会再生产分层体现了资本积累的新路径，存在诸如技术垄断、资本权力跨领域扩张、财富分化、中等收入群体经济基础退化等隐患。本文针对社会再生产分层带来的影响与挑战，结合当前我国扎实推进共同富裕的发展要求，统筹考虑国际国内环境，探究其对未来经济发展的启示。
