“…DEA is an analytical method that studies efficiency problems within operational research, drawing from concepts in management and mathematical economics. Charnes, Cooper, and Rhodes (1978) put forward the first DEA model of C 2 R, which had the following advantages: (a) it can be applied to the efficiency evaluation of multi-input and multi-output; (b) it is not affected by the dimensions of input and output elements; (c) as an objective evaluation method, it is less sensitive to human subjectivity.. Due to these advantages, the DEA model is widely used in economic development (Hu, Zhang, & Chao, 2019), ecological construction (Deilmann, Lehmann, Reißmann, & Hennersdorf, 2016), scientific and technological innovation (Wang, Zhang, Fan, Lu, & Yang, 2019), and other fields. However, the traditional DEA model cannot account for the active decision-making units within the RIS, which may lead to incorrect results.…”
