Service Innovation Research in the World: A Bibliometric Analysis

The purpose of the study is to find out the growth and development of research productivity in service innovation (SI) in the world during the period of 2001-2011. Firstly, we explore the overall growth of SI research, and then investigate cross-country comparisons in its research performances, with the focus on the world share, relative research effort, impact and quality of top ten productive countries. Furthermore, we develop productive institution index, productive author index and productive journal index in the field of SI. The data was retrieved using Web of Science (WOS) database. The cross-country comparisons show that USA is the leading country and has the biggest world share of SI research.
