Abstract
In this paper, we focused on the trend of service design research. Our presumption is that many research deal in new industrial category which is different from current industry classification. Then we could define new service industry framework. However there are no clear new findings of service business structure from this servey.
We conclude that service design research is still on the way to be established research field. User experience is also close situation then we watch such related area to build service design as practical research field.
