Abstract:

Purposes To explore the mechanism of scientific journals in the paper-policy co-construction， so as to enhance their capacity for innovation leadership and knowledge translation. Methods Taking the policy texts， academic papers and column introductions of the new-generation information technology industry from 2015 to 2025 as data sources， 45 authoritative Chinese scientific journals were selected. BERTopic modeling was adopted， and semantic similarity analysis and time-series analysis were applied to distinguish three types of co-construction relationships. The mediating mechanism of journals was verified by combining quantitative indicators with qualitative text analysis， and the mechanism of action and applicable boundaries were elaborated through multi-case comparison. Findings The paper-policy nexus presents three types of co-construction relationships， namely policy transmission， academic diffusion and two-way circulation. As a mediating hub， scientific journals possess the function of two-way transformation； journals participate in the co-construction process through three mechanisms： strategic issue translation， frontier consensus incubation and collaborative knowledge transformation. Conclusions Scientific journals should transcend the role of traditional carriers， and become a strategic bridge connecting knowledge production and application by establishing a context-driven dynamic adaptation mechanism， restructuring the full-chain knowledge translation process， and improving the multi-factor collaborative support system of “talent-institution-technology”.

摘要：

目的 探究科技期刊在“论文-政策”互构中的作用机制，以提升其创新引领与知识转化能力。 方法 以2015—2025年新一代信息技术产业的政策文本、学术论文及专栏导言为数据源，筛选45种权威中文科技期刊，采用BERTopic主题建模，利用语义相似度和时序分析判别3类互构关系，结合量化指标与质性文本分析验证期刊的中介机制，通过多案例比较阐释作用机理与适用边界。 结果 “论文-政策”呈现政策传导、学术扩散与双向循环3类互构关系；科技期刊作为中介枢纽具备双向转化功能；期刊通过战略议题转译、前沿共识孵化、协同知识转化3项机制参与“论文-政策”互构过程。 结论 科技期刊应超越传统载体角色，通过建立情境驱动的动态适配机制、重构全链条知识转化流程、完善“人才-制度-技术”多要素协同支撑体系，成为连接知识生产与应用的战略枢纽。
