The rapid development of digital technology provides new opportunities for the international dissemination of Chinese excellent traditional culture, but it also faces the challenges of cultural translation distortion, technological platform dependency, cross-cultural acceptance obstacles, and operational mechanism defects. Based on the dual perspectives of technology availability and cultural memory theory, this paper systematically analyzes the internal logic of digital technology-enabled cultural international communication, revealing the semantic loss in the digital translation of traditional culture, the communication bias caused by the algorithmic preference of technological platforms, as well as the value conflict in cross-cultural contexts. The study proposes a four-dimensional synergistic path of “content-platform-strategy-mechanism”: building a cross-cultural narrative system through innovative content production, breaking through the ecological dependency of communication by relying on independent technology platforms, optimizing precise communication strategies based on intelligent algorithms, and perfecting institutional safeguards to cultivate the momentum of sustainable development. The study provides strategies for solving the core problems of translation distortion and platform dependence in “culture going overseas”, and has important theoretical and practical value for enhancing the effectiveness of Chinese culture’s international dissemination and strengthening the country’s cultural soft power.
