Abstract： Objectives To establish an evaluation index system for general hospital's sustainable innovation ability of science and technoloby and determine the index weight. Methods Firstly, the theory of scientific and technological innovation was discussed based on the systematic analysis of the related facts from the documents. Secondly, a set of targets was drafted with methods of work breakdown structure (WBS), classification and combination from references to many other studies of science and technology evaluation, and then revised by experts who are familiar with the subject. Thirdly, the weight of each target was decided through Analytical Hierarchy Process (AHP) and questionnaires. Results A systematic and comprehensive evaluation system of the general hospital's sustainable innovation ability of science and technology, comprised 3 first-level indicators, 15 second-level indicators and 37 third-level indicators, which were proved reliable by consistency check. The weights of each indicator were also defined. Conclusions The evaluation system comprises both qualitative and quantitative indicators. The indicators not only reflect the performance of a period, but also reflect the sustainability of large general hospitals' scientific and technological innovation ability. By using the scientific consultation, analysis and statistics, the evaluation system is proved to be valid and reliable.
