A Study on the Cross-cultural Communication Effect of Chinese Aerospace Spiritual Genealogy under the Framework of Ecological Translation Studies

In order to promote the global recognition and identification of the Chinese aerospace spirit, the article analyzes the effect of cross-cultural communication under the framework of ecological translation, and explores the profound impact of cultural appropriateness and media choice on communication effects in the light of computer technology, especially the application of big data analysis and artificial intelligence (AI). While the big data analysis platform effectively gathers new media communication data and highlights the advantages of short video formats in enhancing audience interaction, the emotional expression differences across cultures, and their specific impacts on communication effects, still require further investigation. Audiences in Western cultures tend to be direct and personalized in their emotional expression, while audiences in Eastern cultures pay more attention to collectivism and introverted emotional expression. This emotional difference directly affects the acceptance and cultural identity of the communication content, so when designing the communication strategy, it is necessary to combine the cultural background to adjust the emotion recognition and classification mechanism in the AI algorithm to ensure a more accurate conveyance of the cultural spirit In addition, the application of machine translation technology in cross-language cultural communication also provides technical support for the realization of accurate cultural adaptation. The experimental results indicate that the communication effect score for the Shake platform is 8.5, Weibo is 6.2, and Twitter is 4. By employing the adaptive translation strategy, the cultural identity among Western culture audiences is enhanced by 50%. These findings offer new theoretical foundations and practical support for leveraging advanced computer technology to optimize global cultural communication strategies and strengthen cultural identity.
