Creating an academic and technological landscape of service innovation: An analysis of the citation network

摘要

It is widely recognized that the concept of service innovation is significant for innovation strategy and economic growth especially in developed countries. However, since the term “service innovation” represents a broad sense, there is not the common understanding about what is service innovation even among experts. In this paper, we create an academic and technological landscape of service innovation from a number of academic publications and patents. Not only creating landscapes, extracting the gap between science and technology can be extract by comparing the major topics. As a result, there were mainly eight clusters in science and twelve in technology. SSME research domain is so interdisciplinary that each of eight is not so strongly related to others. On the contrary, all major patent clusters are IT-related ones. In other words, the scientific outcomes are not applied into industries. This result suggests we need to accelerate applying the scientific outcomes into industries.
