| Abstract: | Interdisciplinary research is expected to contribute to industrial and economic development. However, due to expansion of
knowledge and the fragmentation of research fields, knowledge dissemination among different research fields is rare and we
need a methodology for measuring such dissemination and promoting it. In this paper, we introduce a citation lag analysis
of inter- and intra-clusters extracted by citation network analysis as a new indicator to represent the speed of knowledge
diffusion in subfields of a research field. A case study was performed within supply chain research to investigate knowledge
integration among its subfields. Based on the analysis, we discuss knowledge structure and reciprocal influence of subfields
in supply chain research. This study contributes to offering a new approach for analyzing and understanding the development
of boundary spanning research. |
