By analyzing the root causes of the problems affecting the co-construction and sharing of information resources, a crowdfunding model was put forward for the construction of postgraduate education big data information resources guided by the concept of "data utilization oriented data production side reform". According to the data sharing type, different crowdfunding modes were designed for different scenarios, such as cross domain, same field, inter universities, and different departments within the university. Finally, a series of policy suggestions were advanced for the implementation of crowdfunding mode from the aspects of solving data interface, power and security problems of data circulation and improving big data industry chain.
