中国国家安全部近期指控有研究人员在向国际期刊投递论文时泄漏关键技术参数，使得政府部门正考虑将国家安全纳入科学评估体系，加强「公开前审查」与「外发前批准」的监管。
此政策转变反映出中国科技政策从强调全球合作转向加强知识外流控制，部分学者担心这会阻碍其科学雄心，但也有学者支持加强审查，认为中国已在多个领域处于前沿。
Chinese policymakers are discussing ways to reduce incentives for researchers to submit findings to foreign journals, as Beijing worries academic publications could leak industrial and technological innovations, leading to plans to lower the weight of international journal metrics like SCI in promotions.
China's Ministry of State Security recently accused a researcher of leaking key technical parameters in submissions to international journals, prompting government departments to consider incorporating national security into science evaluation and enforcing strict pre-disclosure reviews.
This policy shift reflects a transition in China's science strategy from global collaboration to tighter controls on overseas knowledge sharing; while some worry it may hinder scientific ambitions, others support the scrutiny, believing China is already at the frontier in many fields.
