- Abstract
- Understanding the interaction patterns between science and technology (S&T) is crucial for innovation, yet research observing relationships between different knowledge types within S&T interactions from a knowledge substitutability and complementarity perspective is lacking. This study addresses this gap by analyzing S&T interactions through two indicators: knowledge complementarity and knowledge substitutability. By integrating citations and semantic information from scientific and technological publications, a network is constructed to delineate clusters of tightly interconnected knowledge entities and examine intra-cluster and inter-cluster interactions. In the field of genetic engineering vaccines, the study reveals key insights. Within clusters, scientific and technological knowledge coexist, indicating a close interplay between foundational research and practical applications within the same thematic areas. Technological knowledge exhibits higher substitutability than scientific knowledge. The intensity of intra-cluster interactions correlates with the field's development stage, where active knowledge exchange signifies rapid advancement. Between clusters, initially a central cluster shows high knowledge complementarity with others, implying widespread integration of core concepts across subfields. As the field matures, inter-cluster interactions balance out, reflecting diversification and specialization. Knowledge substitutability and complementarity indices peak in the early stages, then decline and slightly rise thereafter, indicating a shift towards incremental innovation and consolidation of existing knowledge. This study provides a novel methodological framework for measuring S&T linkages, contributing to a deeper theoretical understanding of their dynamic relationship. Practically, it offers insights for promoting technological innovation, thereby informing strategic planning and resource allocation in R&D.
