Abstract：In the context of escalating Sino-American strategic competition， a comparative study of Chinese and the USA digital economy policies bears significant strategic value. Traditional methods of policy comparison are limited by cost，can’t solve this problem well. This paper focuses on the contrast between digital economy policies in China and the USA， proposing a resolution framework based on a cross-language model. The framework initially classifies Sino-American digital economic policies by fine-tuning language models and calculating multilingual similarity， thereby achieving automated comparative analysis of the policy environments. Experiments demonstrate that the proposed method can accurately and eficiently identify and extract policy text features，outperforming baseline methods in accuracy across multiple classification dimensions. Finally，by comparing over 16，Ooo Sino-American digital economic policy texts， this paper reveals key differences in policy tool usage and the focus of digital economic industry development between the two countries，providing a comprehensive and objective portrayal of the disparities in digital economy policy environments. Concurrently，it also brings a fresh perspective to policy comparison research.
