Analysis of China's Green Computing Power Policy Texts based on LDA Model

In recent years, the contradiction between the exponential growth of global computing power demand and energy environmental constraints has become increasingly prominent. It is urgent to build a new efficient and low-carbon computing power system through technological innovation and model transformation. China's green computing power development path not only provides important support for the high-quality development of the digital economy but also contributes a Chinese solution to global ecological governance. This paper systematically analyzes China's green computing power-related policies, In this study, we collect a total of 104 Chinese government policy documents related to “green computing power” issued between January 2007 and May 2025. Using an LDA-based topic modeling approach to extract 13 sub-themes and subsequently perform hierarchical clustering to aggregate them into five major themes. The results provide a comprehensive, data-driven perspective on policy evolution and inform future strategies for advancing green computing power.
