The expansion of urbanization and the rapid growth of cities in the eighteenth century, followed by modernist thinking and changing the patterns of modern human life, have created problems for cities, so that the city as a living creature has lost its own happiness and vitality. The main objective of the research is spatial analysis of the factors affecting the happy city from the viewpoint of citizens in Yazd. In this study, which is a type of applied research, a descriptive-analytical method was used. To collect the required information, documentary studies (theoretical framework of the research) and field studies (such as questionnaire and observation) were used. The population of the study includes citizens in Yazd who are 15 years old or more among which 384 citizens were chosen as the sample. SPSS software and multi-criteria decision-making methods were used to analyze the data. The results showed that there is a reciprocal relationship between the basic variables, education and happiness and there is no relationship between sex, marriage and age variables with happiness, Also, there is no relation between the type of activity and the amount of utilization of urban spaces with happy. There is a direct and significant correlation between the type of access to urban spaces and social dimensions with happiness, and there is a direct and significant correlation between economic dimensions and happiness, conversely, there is no relation between spatial dimensions and happiness. But the Shannon entropy model shows that social-spatial dimensions equally affect happiness, and the economic dimensions are the next priority.
