  In recent years, the expectation that new businesses and economic value can
be created by combining/exchanging data from different fields has risen.
However, value creation by data exchange involves not only data, but also
technologies and a variety of stakeholders that are integrated and in
competition with one another. This makes the data exchange ecosystem a
challenging subject to study. In this paper, we propose a model describing the
stakeholder-centric value chain (SVC) of data by focusing on the relationships
among stakeholders in data businesses and discussing creative ways to use them.
The SVC model enables the analysis and understanding of the structural
characteristics of the data exchange ecosystem. We identified stakeholders who
carry potential risk, those who play central roles in the ecosystem, and the
distribution of profit among them using business models collected by the SVC.
