近年来，数字经济的发展对提高居民收入水平起着重要作用，但其对居民收入结构的影响尚未得到充分认识。本文基于2013~2021年中国大陆30个省份数据（西藏除外）运用联立方程模型进行了实证分析。结果表明：数字经济未对工资性收入和转移净收入占比产生显著影响，数字经济对经营净收入占比具有负向影响，数字经济对财产净收入占比产生正向影响。结合研究结果，政府应支持中小企业在数字经济中的发展，有效改善居民收入结构。

The development of the digital economy has played a significant role in improving income levels, but its impact on the structure of income has not yet been fully understood. This paper uses a simultaneous equation model to conduct an empirical analysis based on data from 30 provinces in mainland China (excluding Tibet) from 2013 to 2021. The results show that the digital economy has not had a significant impact on wage income and net transfer income, but it has a negative impact on net operating income and a positive impact on net property income. Based on the research results, the government should support the development of small and medium-sized enterprises in the digital economy and effectively improve the income structure of residents.
