【摘要】 在当前国际格局深刻变革、世界多极化趋势加剧的背景下，中国科技创新与国际传播面临新的挑战与机遇。研究以人工智能(AI)为切入点，构建“技术伦理-技术效能-技术影响”三维评价框架，通过对18个国家7200位受访者的调查数据分析，揭示全球公众AI认知的差异化格局。研究发现：全球民众普遍认可美国在AI领域的主导地位(60.31%),中国作为唯一具有实质性挑战能力的竞争者位居第二(15%);AI评价呈现显著的“南北差异”,发展中国家对AI持更为积极的态度，而发达国家则表现谨慎；技术影响评价普遍低于其他维度，反映了全球对AI长远社会效应的认知保守。基于这些发现，提出构建“责任技术”叙事体系、实施差异化精准传播策略、建设“技术普惠”发展中国家合作网络等对策建议，可以促进中国科技国际传播效能提升，增强全球话语权，优化国家形象塑造，为应对新形势下国际传播挑战提供实证支持与战略思考。更多还原

【Abstract】 In today’s rapidly evolving international landscape and increasingly multipolar world, China faces both new challenges and opportunities in science and technology innovation and international communication. With the examination of artificial intelligence(AI) as a starting point, this study constructs a three-dimensional framework of “technological ethics—technological effectiveness—technological impact”, and through the analysis of survey data from 7200 respondents across 18 countries, it maps the global perceptions of AI. The findings reveal that the global public widely recognizes the United States as the dominant player in AI(60.31%), with China ranking second(15%) as the only significant challenger; a notable “North-South Divide” exists, with developing countries showing more enthusiasm toward AI while developed nations remain cautious; and assessments of AI’s technological impacts score consistently lower than other dimensions, indicating widespread conservative views about AI’s long-term societal effects. Based on these insights, this paper proposes strategies including developing a “responsible technology” narrative, implementing regionally-tailored communication approaches, and creating “technology for all” partnerships with developing nations. These suggestions aim to enhance China’s international science and technology communication effectiveness, strengthen its global voice in technological discourse, improve its national image, and provide evidence-based support and strategic thinking for responding to the challenges of international communication in the new context.更多还原
