We find that type (Tsaur, 2001;Hwang & Chang, 2003;Chen, 2007;Barros & Dieke, 2008;Hu et al, 2009Hu et al, , 2010Chen et al, 2010;Assaf et al, 2010), location (Hwang & Chang, 2003;Barros & Mascarenhas, 2005;Chen, 2007;Hu et al, 2009;Hu et al, 2010), scale (Barros & Mascarenhas, 2005;Assaf et al, 2010), and the distance to the international airport (Hu et al, 2009;Chen, 2010;Shieh et al 2014) are four variables used mostly in the existing literature for explaining the hotel efficiency.
