The purpose of this study is to investigate the relationship between sustainable tourism development and improvement of social welfare indices based on structural equation analysis. Based on the new theoretical approaches, some hypotheses have been developed that this research is descriptive and correlational. The population of the study consisted of all the inhabitants of the villages of Koohrang city with 5 persons. Researcher-made questionnaires (using existing theoretical background) on tourism development, social welfare were used as research tools. Statistical analysis was performed based on structural equation using Spss and Amos software. The results showed that there is a significant relationship between tourism development and social, economic, legal, educational, demographic and social dimensions of social welfare. Also the regression values of the structural model indicate that the variable of rural tourism development among the social welfare dimensions has the most effect on the social dimension (ß=0.42) and then on the demographic dimension (ß=0.40) and economic dimension (ß=0.34) respectively.  legal dimension (V=0.28), biological dimension (ß=0.27) and least impact on educational welfare dimension (ß=0.24).
