跨国数据分析机构报告：全球科研合作重心转向中国

Core Viewpoint - A recent study indicates that the center of global scientific collaboration is shifting towards China, with significant growth in partnerships with European countries and emerging regions like Southeast Asia, the Middle East, and Africa [1][2]. Group 1: Research Findings - The study, based on 25 years of international collaboration data from Clarivate's Web of Science database, shows that China's scientific output has more than doubled in the past decade, surpassing the U.S. in research paper production by 2020 [1]. - China is expected to lead in citation counts as well, while the U.S. has seen stagnation in both the quantity and quality of published papers, failing to recover from declines during the COVID-19 pandemic [1]. - The report highlights a significant decrease in U.S. research output and citation rates, which began to accelerate around 2018, indicating a long-term trend of decline [2]. Group 2: U.S.-China Collaboration Dynamics - U.S.-China scientific collaboration has stagnated since 2019, which has historically been a crucial component of the U.S.'s overall citation influence [2]. - Factors contributing to this decline include U.S. government policies that cut research funding, limit international student numbers, and target key research areas like vaccines and climate change [2]. - Experts warn that barriers set in the name of "national security" and economic competitiveness could harm the global scientific community, moving away from a previously collaborative environment [2].
