Two-phase Data Envelopment Analysis based Industrial Structure Evaluation
Jingru Pan, Shifu Shan · 2025
With developing expenditure on R&D activities of Industry Enterprises Designated Size (IEDSs) in China, it is essential for evaluating effectiveness of R&D of China IRDSs. Though, certain studies in R&D effectiveness measurement on Chines IEDSs have taken internal architecture of R&D production process. Patent Intensive Industry have essential role in innovation, that is essential for evaluation techniques to its phases and variance of innovation effectiveness. This research developed the new definition technique to patent intensive industry with invention proportion in force and R&D full-time equivalent on personnel, separated innovation process to technique R&D phase and S&T obtain transmission phase. The basic process involves three phases, choosing two-phase Data Envelopment analysis method with shared input as estimation technique through comparing, developing estimation index through analysis of past researches and extracted the evaluation information. This provided target industry policy suggestion through separating patent intensive industry to 4 classes. This article represents developed technique is appropriate for innovation effectiveness for patent intensive industry and their research framework is employed for evaluation of different industries.
