Abstract: 【Purpose/significance】Innovation efficiency has always been an important research content in the field of technical intelli⁃gence,especially scientometrics.With the deepening of innovation theory research and the continuous enrichment of data and analysis models,the measurement of innovation efficiency from an interdisciplinary perspective is becoming a new research topic【. Method/pro⁃cess】This study uses the method process of "grounded theory" to construct a set of innovation efficiency measurement index system from an interdisciplinary perspective. At the same time, in view of the shortcomings of the classical efficiency measurement model,around the internal process and periodic characteristics of innovation activities,this study integrates the dynamic network SBM model with the super efficiency model and the evaluation idea of cross efficiency,this paper constructs the measurement model of regional sci⁃entific and technological innovation efficiency,and takes the Yangtze River Delta as an example to compare and apply the model【. Re⁃
sult/conclusion】The empirical results verify the effectiveness of the model in solving the discrimination of efficiency values of mul⁃tiple effective units and the incompatibility of efficiency values under the self-evaluation system.【Innovation/limitation】This study measures innovation efficiency from the internal process and dynamic changes of innovation activities,and makes up for the poor dis⁃crimination and incompatibility of efficiency values in the classical efficiency measurement model.In the future,it is considered to im⁃prove the index data and give reasonable weight to it,and carry out large-scale simulation analysis by using computer technology.
