Based on the data of 7031 sample farmers in Chinese Social Survey （CSS） Database in 2019 the study shows that digital technology plays the role of “bridge” in promoting the common prosperity of farmers on the whole.The use of digital technology will increase farmers’ access to common prosperity.The conclusion holds true for farmers with different purpose and frequency of digital technology.The study findings remain robust when re-estimation is carried out by replacing explained variables and models.Further analysis shows that the use of digital technology still plays a significant role as a “bridge” in promoting the common prosperity among farmers，considering the differences in digital technology access areas，professional characteristics and gender types.However，the effect has different impact on the interviewee’s class identity and educational level.Digital technology use has a significant “bridge” effect on the common prosperity with self-class identity of “middle”，“upper” and higher human capital group，but for the interviewee with self-class identity of “low” and lower human capital group，the effect of digital technology use didn’t pass the significance test.Therefore，the “capability gap” on the internet usage level is the key to restrict the “bridge” effect of digital technology use to promote common prosperity.The above conclusions provide new ideas for the implementation of the “Digital Empowerment Action for Rural Residents” and help farmers use digital technology to promote common prosperity.
