Abstract: 【Purpose/significance】This paper discusses the social reproduction problems in the era of digital economy, which can help
accelerate the development of digital information industry and digital economy in the great changes of our country【. Method/process】This paper comprehensively uses historical logic, theoretical logic and realistic logic to analyze the transformation of kinetic energy and information security of social reproduction in the era of digital economy【. Result/conclusion】The typical feature of digital economy era lies in the digitization and informatization of social reproduction, which is based on data factor and factor data, and its essence lies in the transformation of economic development momentum. In the era of digital economy, digital information will be deeply embedded in the process of social reproduction. While effectively improving the efficiency of social reproduction, it will also expose many infor? mation security problems. In the age of digital economy, information security should be emphasized to ensure the smooth progress of so? cial reproduction.【Innovation/limitation】This paper discusses social reproduction in the era of digital economy from the perspective of kinetic energy conversion, and then settles on the problem of information security. The research perspective is novel, but it focuses on theoretical analysis, and the subsequent research needs to strengthen empirical analysis.
