摘要

This research overviews and analyses the studies on venture businesses, start-ups, or entrepreneurs which play more and more important roles in our societies through the analysis by time-series approach and by individual countries. Firstly we extracted academic papers including the words "venture," "start-up," or "entrepreneur" in the titles and abstracts from the Web of Science provided by Thomson Reuter's with data from 1991 to 2015. With these search queries we extracted 87,733 papers. Then we conducted citation analysis for these papers using network analysis by each additional five years in the 25 years and checked changes of the keywords contained in main clusters by these terms and by countries. From the result of this analysis, we figured out how the most important articles have been cited in their cluster in this research field over time and found the difference of clusters by countries where they have relatively more shares of papers. Additionally the share of papers published in Japan totally has come down into the only about 1% in this field and less share especially in emerging clusters. On the contrary, China has had more influence on this research field since the beginning of this century.
