Under the background of digital technology, the construction of philosophy and social science discourse with Chinese characteristics is urgent. By analyzing the impact of digital technology innovation on the discourse system, it is found that natural language has the trend of replacing artificial language, new media technology has changed the traditional discourse communication mode, and the digital knowledge system has reconstructed the discourse content. The discourse construction of philosophy and social sciences with Chinese characteristics is faced with such problems as the risk of discourse subject alienation brought by virtual communication, the difficulty of high-quality discourse production brought by information overload, and the elimination of discourse guidance power of mainstream media brought by interaction. Therefore, we need to construct the discourse subject of philosophy and social sciences with digital thinking, pay attention to the digital production and dissemination of high-quality discourse of philosophy and social sciences, and strengthen the “Chinese characteristic” value of the discourse construction of philosophy and social sciences, so as to conform to the innovative development of digital technology and enrich the content system of philosophy and social sciences with Chinese characteristics.
