“…The evaluation of the efficiency and performance of the innovation system remains a high priority in order to improve innovation policies and practices. A data envelopment analysis (DEA) methodology has been successfully applied to measure the efficiency of innovation systems on both national ( Pan et al., 2010 ; Cullmann et al., 2011 ; Afzal, 2014 ; Tarnawska and Mavroeidis, 2015 ; Prokop and Stejskal, 2017 ; Anderson and Stejskal, 2019 ; Aguilar-Barceló and Higuera-Cota, 2019 ; De la Vega et al., 2019 ) and regional level ( Zabala-Iturriagagoitia et al., 2007 ; Chen and Guan, 2012 ; Broekel et al., 2018 ; Fadeyi et al., 2019 ; Zemtsov and Kotsemir, 2019 ; Zhuang et al., 2021 ). When analysing the efficiency of innovation systems, the DEA methodology is usually used by examining the input-output components in order to model a robust efficiency measurement.…”
