التحليل متعدد الأبعاد للمتغيرات السياحية والبيئية باستخدام طريقة المركبات الأساسية (‏pca‏) ‏

This paper aims to examine the contribution of tourism and environmental variables in the ‎composition of Principal Components using the factorial analysis (Principal Components analysis) ‎through the theoretical analysis of the relationship of tourism with environment, and then to ‎present the variables used in the study consisting of 20 variables (10 environmental variables and ‎‎10 tourism variables) for a sample of 163 countries and implicating the Principal Components in ‎the empirical part. The results of the study found that tourism expenditure as a percentage of ‎imports and the nitrous oxide emissions from agriculture and methane emissions from energy ‎contributed the Principal Components, as well as the contribution of tourism revenues as a share ‎of exports and nitrous oxide emissions in the energy sector and carbon dioxide emissions ‎resulting from the consumption of gaseous fuel in the composition of other Principal ‎Components.‎
