Abstract (in Japanese) (See Japanese page) 
(in English) API Economy is expected to increase collabration between information services, and thereby, is expected to increase market value from service innovations. In this paper, we introduce a market model for API economy, and clarify social welfare under several competitive model between API providers. Numerial examples show that Bertrand competition outpeforms other competition over a wide range of parameter, although Cournot competi-tion performs best under a specific parameter. We also show that the parameter representing complementarity between APIs is important for increasing the social welfare.
