With the continuous development of modern economy, people's pursuit of happiness is increasing. Therefore, in order to study what factors affect residents' subjective well-being, this thesis explores the relationship between economic and demographic variables and subjective well-being, and utilizes methods such as chi-square test and Pearson correlation analysis to study the impact of each factor on well-being. In addition, regression equations for happiness are established to explore the interaction between the factors and their impact on subjective happiness. The innovation of this thesis is that it combines the effects of economic and non-economic factors on happiness, which can explore the influencing factors of happiness more comprehensively. However, most of the data in this thesis come from the Chinese database and the World Values Survey, which may lead to the limitations of the final conclusion, which is also a shortcoming of this thesis.
