Health,happiness and family economic satisfaction have become important evaluation indicators of China’s urbanization process and urban and rural planning.In this paper,residents’ subjective well-being consists of health,happiness,family economic satisfaction,and so on.Based on the sample survey data of 14,600 residents in 401 neighborhoods of 124 cities in China,the paper explores the relationship between urbanization,urban planning and residents’ well-being using descriptive statistics,multilevel mixed-effects generalized linear model and multilevel mixed-effects logistic regression model.The results show that in the spatial distribution of residents’ well-being,residents living in cities with low per capita GDP have a low level of well-being,and residents in economically developed cities have a higher level of well-being;but the level of well-being of residents living in cities with urbanization rate greater than 70% is significantly lower than those living in cities with urbanization rate from 50% to 70%.This study proves that there is a turning point in residents’ subjective well-being under the current urbanization mode.In other words,the relationships between urbanization rate and residents’ well-being,economic development and residents’ well-being,population scale and residents’ wellbeing follow an inverse-U shape.These results confirm the rationality of China’s urban planning in pursuit of economic growth for the purpose of improving residents’ living standard.Additionally,it also reflects that the current poor-quality urbanization mode may harm residents’ well-being.Finally,we put forward that,in the background of slowing economic growth,the improvement of social welfare should be the direct target of urban and rural planning,to meet the new requirement of national governance in the new era.
