| The pursuit of happiness is the goal of an individual ’s life.The study of happiness has always been an important issue in economics,sociology,management and psychology.Since China ’s reform and opening up,economic development has achieved remarkable results,people ’s living standards have been greatly improved,and residents ’ happiness has also been improved.During his visit to Guangxi in 2021,General Secretary Xi Jinping said affectionately," Making the people happy is the great country.”Therefore,happiness is not only the common pursuit of the people,but also the main goal of government governance.However,in the World Happiness Report released by the United Nations,China ’s mainland is still at the middle and lower levels compared with other countries.Therefore,in order to consolidate the achievements of economic development and promote common prosperity of society,it is of far-reaching significance to study how to improve residents ’ happiness.Based on Maslow ’s hierarchy of needs theory,welfare state theory and new public service theory,this paper takes the data of China General Social Survey(CGSS)in 2015 as the data source,and makes an empirical analysis of the original data after screening and processing.Firstly,the explanatory variables,explanatory variables and control variables are preliminarily analyzed.Secondly,the Ordered Logit regression model is used to study the impact of class mobility perception and public service satisfaction on residents ’ well-being,and the robustness of the results is tested.The OLS regression model and the ordered Probit model are used as the substitution measurement model to test whether the basic regression results are robust.Thirdly,Bootstrap method is used to test whether public service satisfaction has a mediating effect between class mobility perception and residents ’ happiness.Finally,further heterogeneity analysis is carried out from multiple perspectives,and the impact of class mobility perception and public service satisfaction on residents ’ happiness is analyzed based on urban-rural dual structure and regional characteristics.The results show that :(1)The perception of class mobility has a significant positive effect on residents ’ well-being.(2)The adequacy,balance,convenience and inclusiveness of public services have a significant positive effect on residents ’ well-being,and the impact of adequacy and inclusiveness on residents ’ well-being is greater than that of balance and convenience.(3)The four aspects of public service are summed up to obtain the mean value as a variable of public service satisfaction,and the mediating effect model is used to test the mediating effect of public service satisfaction.The results show that public service satisfaction plays a partial mediating role between class mobility perception and residents ’happiness.(4)The influence of class mobility perception and public service satisfaction on residents’ happiness has some heterogeneity based on the urban-rural dual structure and regional characteristics. |
