| Research Abstract |
The vitalization of the service sector is one of the major economic issues in Japan, where the service sector accounts for more than 70% of GDP. However, empirical studies on the innovation factors and productivity in the service sector have faced significant difficulties due to problems of the sectoral classification (e. g. existence of establishments with varying characteristics of the innovation system in each sector). This paper challenges the problem by making categories based on the characteristics of the innovation system for the Japan Standard Industrial Classification (JSIC) service sectors (4-digit). Applying a text mining method, we quantitatively measure sensitivities of three innovation factors, and reveal the characteristics of the innovation system which each service sector has. We also classify the JSIC service sectors (4-digit) into 8 eight categories that have specific innovation potential in according to the proper innovation system obtained from the revealed characteristics.
