当前转基因争议的恶性循环中，大众媒介的知识生产遭遇科学家面临信任危机、利益诉求的属性难以判断，以及新闻记者科技素养与科学家媒介素养双重落差等焦虑和困惑。那么，如何在知识生产中调整二者之间的关系？本文认为，作为消息来源与关键知识生产主体的科学家与新闻记者是一种竞争性共生的互动关系。要释放争议，消解大众媒介知识生产的焦虑，关键是重建科学家与记者之间信任。通过激励机制，在“科-媒”合作传播模式的基础上，重构基于公众责任与利益框架内的合作关系和信任文化，形成稳定的社会知识生产体系，增加消解转基因争议恶性循环的可能性。

Due to the crisis of scientists’ credibility and the difficulty of distinguishing the stands of scientists, making the genetic modification debate in mass media full of anxiety and confusion. How to deal with the relationship between scientists and journalists in the process of scientific knowledge production? This paper illustrates that the relations between scientists and journalists, who are key sources and producers of scientific knowledge, are competitive symbiotic. Thus, the key to solve this problem is to rebuild the trust through the mode of "scientists-media" and incentive mechanism. Only in this way, can scientists and journalists enhance their cooperation based on public responsibility and mutual trust.
