“…The data on the frequency with which each topic has been addressed are contained in the following table (Table 5). The research topic that most frequently appears in the papers analysed involves performance (21.51%), which is studied from the perspective of different theories, such as Contingency theory (Ceci & Masini, 2011), Linear programming (Geng, Chu, Xue & Zhang, 2011), Resource dependence theory (Shah, Jajja, Chatha & Farooq, 2020;Chang et al, 2019), Agency theory (Datta, 2020), Game theory (Arabi, Mansour & Shokouhyar, 2018;Gómez & Heredero, 2013;Hezarkhani, 2017;Lee et al, 2016) and Resource-based theory (Fang, Palmatier & Steenkamp, 2008;Yan et al, 2020;Zhang et al, 2019), These results are consistent with those reported by Wang, Lai, and Shou (2018), identifying numerous studies that analyse the impact that servitization has on performance.…”
