本文从实体和语义视角量化学术与产业知识接近度,揭示技术变革对两者共演的影响及知识主导地位的变化。

摘要:

学术界和产业界呈现出相互塑造和动态反馈的特征。尽管存在不同的制度逻辑,它们在联合出版和人才流动方面已经形成了紧密的合作,表现出制度分化与高强度合作之间的张力。现有研究对两者知识接近度的分析主要依赖于宏观指标,如联合论文或专利数量,缺乏对文献中知识单元的分析。这导致对产业与学术之间精细知识接近度的理解不足,可能影响合作框架和资源配置效率。为了解决这一限制,本研究通过精细的实体和语义空间量化学术-产业共演的轨迹。在实体测量部分,我们通过预训练模型提取精细的知识实体,利用余弦相似度测量序列重叠,并通过复杂网络分析分析拓扑特征。在语义层面,我们采用无监督对比学习来通过测量跨机构文本相似性量化语义空间中的趋同。最后,我们利用引用分布模式来检验双向知识流动与相似性之间的相关性。分析发现,学术与产业之间的知识接近度上升,尤其是在技术变革之后。这为共演中的双向适应提供了文本证据。此外,学术界的知识主导地位在技术范式转变期间减弱。本文的数据集和代码可通过https://github.com/tinierZhao/Academic-Industrial-associations获取。

英文摘要:

The academia and industry are characterized by a reciprocal shaping and dynamic feedback mechanism. Despite distinct institutional logics, they have adapted closely in collaborative publishing and talent mobility, demonstrating tension between institutional divergence and intensive collaboration. Existing studies on their knowledge proximity mainly rely on macro indicators such as the number of collaborative papers or patents, lacking an analysis of knowledge units in the literature. This has led to an insufficient grasp of fine-grained knowledge proximity between industry and academia, potentially undermining collaboration frameworks and resource allocation efficiency. To remedy the limitation, this study quantifies the trajectory of academia-industry co-evolution through fine-grained entities and semantic space. In the entity measurement part, we extract fine-grained knowledge entities via pre-trained models, measure sequence overlaps using cosine similarity, and analyze topological features through complex network analysis. At the semantic level, we employ unsupervised contrastive learning to quantify convergence in semantic spaces by measuring cross-institutional textual similarities. Finally, we use citation distribution patterns to examine correlations between bidirectional knowledge flows and similarity. Analysis reveals that knowledge proximity between academia and industry rises, particularly following technological change. This provides textual evidence of bidirectional adaptation in co-evolution. Additionally, academia's knowledge dominance weakens during technological paradigm shifts.
