Abstract: Facing the challenges from the open market and fierce competition, it is urgent to establish systematic methodologies for the business model of e internet of things (e-IoT) so as to provide a realistic and feasible business logic for e-IoT constructions. Based on strategic management theory and related business model theories, considering the requirements and features of e-IoT, this paper constructed a theoretical framework and an architecture design method for e-IoT business model. In the theoretical framework the research interfaces covering macro, medium and micro perspectives are clearly defined, and then the research and design methods for the business model with the corresponding enterprise layer, business layer and project layer are put forward. The architecture design mainly focuses on medium and micro perspectives. The paper outlined and refined six fundamental elements into the basic framework, then formulated the logic framework as “Three links, One circulation” and the design principal as “elements layer – analysis layer – output layer – project layer”, and eventually came up a novel business model named as e-IoT MAPPER.
