The purpose of this study is to examine the effect of independent variables on the life satisfaction of new generational rural exodus workers in Chines cities focusing on social capital factors. For this purpose, a social survey was conducted, the sample of which was 335 cases of rural exodus workers working in Shanghai, Nanjing, Ningbo from rural areas of Guangyuan, Sichuan Province. Data analysis was conducted by using SPSS18. The main results are as follows. Residential environment, income, marital status and self-esteem influenced the life satisfaction of workers in terms of demographic and individual character factors. Reciprocity norm, informal participation, private reliance, and informal network were found to be important influential factors in terms of social capital factors, while general norm, formal participation, public reliance, formal network were not significant influential factors. This means that the human relation, so called guansi(關係), is an important factor to influence the life satisfaction of workers and that informal social capital is more influential than formal social capital. The importance of reciprocity norm as the most influential social capital factor means that the traditional mutual support among people are still relevant in the urban lives of new generational rural exodus workers in Chinese cities. In view of the importance of residential environment and informal social capital as the influential factor on the life satisfaction of new generational rural exodus workers, it is necessary to improve the quality of rural exodus workers’ residence and social programs for workers to develop informal social capital. And in terms of formal social capital of workers the task is ahead to create a high-reliant social system in the formal institutions in China.
