Digital infrastructure construction implements and demonstrates the essential requirements of common prosperity.Based on China Household Financial Survey(CHFS)from 2011 to 2019,and with a quasi-natural experiment of the"Broadband China"strat-egy,we investigate the relationship between digital infrastructure construction and household income.This study has found that digital infrastructure construction significantly increases household income and effectively suppresses income gaps.From a functional mecha-nism perspective,the construction of digital infrastructure generates significant"entrepreneurial effects"and"employment effects"by increasing opportunities for entrepreneurship and job creation,thereby boosting household incomes.The household income effect of dig-ital infrastructure construction is more significant in cities,areas with a high urbanization rate,and among middle-aged and higher-educated groups,showing noticeable regional differences and human capital differences.
