“…Nevertheless, such indices are largely confined to the measurement of final operational outcomes, ignoring the efficiency of resource input utilization (Tsai et al, 2011) and neglecting the multidimensional aspects of hotel industry operations (Yu and Chen, 2016). To tackle such deficiency, some scholars introduced parametric approaches such as stochastic frontier analysis (SFA) by considering multiple inputs and outputs of a hotel and assessed its efficiency by measuring its deviation from an optimal frontier (Arbelo et al, 2017;Assaf, 2012;Barros, 2004;Barros, 2006;Lin, 2011). Additionally, another common approach in efficiency assessment is a nonparametric approach of data envelopment analysis (DEA) (Charnes et al, 1978), in which an efficiency frontier is constructed reflecting a firm's minimum resource usage for a given level of output (Liu et al, 2018).…”
