“…For example, Keynes (1936) advanced a multiplier principle using a macro-economic model that studied the relationship between the elements providing the foundation for explaining tourism effects and their related effects for researchers in this field of study. Recent international studies on the topic have typically focused on, for example, the evaluation of tourism land use (Balli, Balli & et al, 2016;Lemelin R. H. et al, 2015;Ruhanen L. et al, 2015); tourism communities' participation (Lee, 2013;Yang et al, 2013); the sustainable development of tourism (Buckley, 2012;Budruk et al, 2011;Sanagustín Fons, 2011); and tourism and environmental protection (Wells, 2015;Zu-yong et al, 2013). Meanwhile, research studies in China concerning tourism have chiefly concentrated on tourist resorts (Liu, 2003;Wu, 1998); the evaluation of tourism's resources (Jiang et al, 2004;Li, 2000;Li et al, 2013); the development of tourist destinations (Ma, 2011;Ren & Wang, 2011;Wang & Zhu, 2012); tourism and urbanization (Chen & Bao, 2012;Chen et al, 2008;Zhang et al, 2008), and so on.…”
