As a pioneer of the global MOOC campaign, a few American research universities, represented by the University of California at Irvine (UCI), upholding the concept of sustainable development, created a series of successful MOOC business models, that have achieved the balance of payments or preliminary profits. However, as a new thing, these business models still face many practical difficulties that need effective solutions. Therefore, this paper attempts to study the business model of UCI MOOC through a group interview with its faculty and reveals the existing problems. Specifically, the following are discussed:the management of key resources needs to be improved; the effect of key activities is questioned; the deepening of the connection with customers is less effective; the expansion of income sources is hindered; there is uncertainty in the promotion of channels; value proposition needs to be clarified; the customer segmentation is less balanced; cost structure needs to be optimized; the important partners need urgent and further attention. Facing severe market environment, we can try to build a three-tier MOOC business model canvas to promote the sustainable development of massive open online courses.
