There are many kinds of value creation relationships between users, platform and society, platform, user and society. Platform business model, which is accompanied by platform enterprises, has become the most significant business model innovation since the 21 st century. Platform based business model innovation provides new forms and solutions to solve the common social and environmental problems faced by human society. However, the reality that can not be ignored is that in recent years, many new social problems have emerged in the process of platform business model innovation, which has brought severe challenges to the traditional business model dominated by market logic. How to realize the transformation and innovation from platform business model to platform sustainable business model has also become a prominent topic of research.Firstly, this paper reviews the connotation of business model and sustainable business model, and clarifies the core connotation and internal logic of business model from the perspective of transaction structure, technology, organization and management, value creation and strategy. The sustainable business model is based on stakeholder theory and corporate social responsibility, which not only creates value for customers, but also creates comprehensive value for society and natural environment. In the supply chain of sustainable business model, suppliers are also responsible for the company's stakeholders. At the customer interface incentive level, sustainable business model encourages sustainable consumption,and customers are responsible for their consumption and the company's stakeholders. Finally, in the aspect of financial performance, it reflects the appropriate allocation of economic costs and benefits among the participants, and considers the ecological and social impact of the company, so as to clarify the systematic transcendence of sustainable business model as a new theoretical paradigm to the theoretical meaning of traditional business model. Furthermore, this paper discusses the new value logic and reconstruction of the business model of platform enterprises under the guidance of sustainability,and focuses on the realization of the sustainable business model under two subdivision scenarios under the platform context. The sustainable business model of shared platform mainly focuses on the recycling and sustainable utilization of resources and the social reconfiguration to achieve sustainability and create comprehensive value and shared value. Under the platform economy, the platform firms based on commercial transactions is mainly based on the embedded concept of corporate social responsibility. By embedding the corresponding social responsibility practice issues or social responsibility practice platform interface, the related social environment problems in the operation process of the platform can be solved by the power of the platform business ecosystem, so as to create sustainable comprehensive value, or by building a social responsibility practice platform or social innovation platform based on a certain social problem driven by sustainable oriented entrepreneurship of social entrepreneurship or co benefit entrepreneurship, and build a benefit organization to drive the platform sustainable business model and innovation. In the future, the research on sustainable business model in the context of platform needs to be further explored from two aspects, one is the basic theory of endogenous integration and governance of corporate social responsibility, the other is empirical research about driving factors, impact effects and evaluation of sustainable business model.
