Extension theory and its application in evaluation of independent innovation capability

Purpose – The purpose of this paper is to apply a new idea and scientific method to evaluate the enterprise's independent innovation capability accurately.Design/methodology/approach – The matter‐element, extension set and independent function in extension theory are introduced briefly. Based on extension theory, the matter‐element model on comprehensive evaluation of the enterprise's independent innovation capability is established. Then, an instance which makes structural analysis on the enterprise's independent innovation capability with extension evaluation method is given.Findings – The matter‐element model on comprehensive evaluation of the enterprise's independent innovation capability is established. Extension evaluation method can combine qualitative analysis and quantitative analysis to reflect the changing process of the objective appropriately. By means of the matter‐element model, the evaluation result shows which the grade does the enterprise's independent innovation capability belong to.Res...
