This paper studies the positive or negative impacts of the development of digital economy on China under the policy background of carbon peaking and carbon neutrality. First of all, it predicts the future under the rapid development of digital economy based on different literature materials. The increasing demand for calculation, storage and flow data of communication technology as well as the fixed network iteration are influential factors to make an analysis of the overall increase in carbon emissions, and then update measures taken by different enterprises under this policy, such as high-carbon enterprises to develop more clean energy and improve smart grid systems. Low-carbon industries pay more attention to the greening of the entire production line and the digital tracking of products after sale in order to achieve a more effective circular economy. The highlight of this paper lies in the lack of literature on the integration of emission reduction measures for enterprises of different modes based on the increase of carbon emissions brought by the future digital economy, and gives relevant examples.
