Abstract: The performance evaluation of digital resource is a multi-index comprehensive evaluation on the nature of its evaluation. The theoretical basis in constructing the multi-index comprehensive evaluation index system should include the target consistency theory, system evaluation theory, stakeholder theory and the quantitative and qualitative combination. The components can be divided into five elements: the contents of digital resource, the ability to supply the digital resource retrieval system, the usage of users, the analysis of cost(digital resources service input) and the situation of digital resources service. The structure design of this system generally adopted the stratification method, which was divided into three levels: the total target layer, the standard layer and the index layer, respectively reflecting the systematization, hierarchy and correlation of the index system, and was also convenient for quantitative evaluation.
