Since the number of electric vehicles is increasing rapidly, there is urgent need to nurture this emerging industry’s business ecosystem. The livelihood of an EV business ecosystem is important to different ecosystem participants: industrial participants, government agencies, industry associations, customers, and other relevant stakeholders, all these participants want to know whether their ecosystem is healthy and performing well. However, there exists no research focusing on the health of EV business ecosystem as health is typically regarded from a project scope. This paper proposed the concept of EV business ecosystem health degree based on the theory of business ecosystem and the evaluation of its health. A four-layer index system is developed from aspects of system coordination, system functionality and system suitability. An improved matter-element extension model combined with TOPSIS is constructed to assess the health status of the EV business ecosystem. The weight of each indicator is calculated using the projection pursuit which is optimized by firefly algorithm (FA). Furthermore, the closeness and characteristic value are calculated to grade the EV business ecosystem health. Finally, the EV business ecosystem in Beijing is taken as an example to confirm the operability and effectiveness of the proposed evaluation index system and model. It is testified that the projection pursuit and an improved matter-element extension combined with TOPSIS model outperforms in reflecting actual condition and can be applied to EV business ecosystem health assessment.
