Abstract:The service performance evaluation of national scientific data platform is an important index to measure its development quality, and the efficiency measurement is an important basis for performance evaluation. The service process of resource provider of national ecological science data center is divided into two related stages: resource service stage and knowledge transformation stage. The index system was constructed from three dimensions: the use efficiency of input-output factors, the utilization degree of scientific resources and the service quality perceived by users. The two-stage DEA-SFA model was used to measure the service efficiency of 43 resource providers, and the super-efficiency model was used to further distinguish and rank effective DMU.The results showed that the average pure technical efficiency values of resource providers in the resource service and knowledge transformation stage were 0.794 and 0.838, respectively, and the number of DEA effective sites were 12 and 16, respectively. Among the 43 decision units, excellent resource providers accounted for about 16%, general resource providers accounted for about 70% and poor resource providers accounted for about 14%. In addition, the service efficiency of resource providers has a certain correlation with the level of regional economic development, and the eastern region is better than the central and western region.Finally, based on the research results, this paper puts forward some countermeasures to promote the development and construction of China"s national scientific data platform.
