Based on the CFPS data from 2010 to 2020 and the list of \u201cBroadband China\u201d demonstration cities, this paper employs a multi-period Difference-in-Differences (DID) approach to empirically analyze the impact of digital infrastructure construction on the health of low-income rural residents and its mechanism. The results indicate that: (1) Digital infrastructure construction had a significant positive impact on the health of rural low-income residents. After adjusting the sample period, changing the policy implementation time point, excluding other policy interference, and Propensity Score Matching-Difference-in-Differences (PSM-DID), the model was still robust. (2) The mechanism test found that digital infrastructure would improves the health of rural low-income residents through three mechanisms: the adoption of new agricultural technology, land transfer, and leisure time. (3) In terms of heterogeneity analysis, based on region type, education level, marital status and public supporting system, digital infrastructure construction can enhance the health status of low-income rural residents in the western region, those with low education level, married people and those with more public supporting system. This study suggests the continued promotion of the construction of digital infrastructure, with a focus on the construction level of the western and western regions, narrow the \u201cdigital divide\u201d between different groups, and improve public supporting facilities in backward rural areas, so as to further enhance the health status of low-income groups.<\/jats:p>","DOI":"10.3389\/fpubh.2025.1503522","type":"journal-article","created":{"date-parts":[[2025,3,12]],"date-time":"2025-03-12T08:09:44Z","timestamp":1741766984000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["A study on the impact of digital infrastructure development on the health of low-income rural residents: based on panel data from 2010 to 2022"],"prefix":"10.3389","volume":"13","author":[{"given":"Qian","family":"Wang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhen","family":"Ning","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meichun","family":"Tan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,3,12]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"103089","DOI":"10.1016\/j.apgeog.2023.103089","article-title":"The evolution of China's rural depopulation pattern and its influencing factors from 2000 to 2020","volume":"159","author":"Hu","year":"2023","journal-title":"Appl Geograp."},{"key":"B2","doi-asserted-by":"publisher","first-page":"67","DOI":"10.1016\/j.chieco.2019.03.009","article-title":"Agricultural inputs, urbanization, and urban-rural income disparity: evidence from China","volume":"55","author":"Wang","year":"2019","journal-title":"China Econ Rev."},{"key":"B3","first-page":"723","article-title":"Health care in China: a rural-urban comparison after the socioeconomic reforms","volume":"71","author":"Shi","year":"1993","journal-title":"Bull World Health Organ."},{"key":"B4","doi-asserted-by":"publisher","first-page":"1","DOI":"10.1186\/s12992-019-0486-6","article-title":"The development and reform of public health in China from 1949 to 2019","volume":"15","author":"Wang","year":"2019","journal-title":"Global Health."},{"key":"B5","doi-asserted-by":"publisher","first-page":"461","DOI":"10.1111\/j.1728-4457.2006.00133.x","article-title":"Income inequality, unequal health care access, and mortality in China","volume":"1","author":"Zhao","year":"2006","journal-title":"Popul Dev Rev."},{"key":"B6","doi-asserted-by":"publisher","first-page":"7590","DOI":"10.3390\/ijerph19137590","article-title":"Study on the impact of income gap on health level of rural residents in China","volume":"19","author":"Guo","year":"2022","journal-title":"Int J Environ Res Public Health."},{"key":"B7","doi-asserted-by":"publisher","first-page":"1831","DOI":"10.1016\/j.eap.2023.11.004","article-title":"The road to entrepreneurship: the effect of China's broadband infrastructure construction","volume":"80","author":"Huang","year":"2023","journal-title":"Econ Anal Policy."},{"key":"B8","doi-asserted-by":"publisher","first-page":"1416","DOI":"10.3390\/land12071416","article-title":"Rural China staggering toward the digital era: evolution and restructuring","volume":"12","author":"Ren","year":"2023","journal-title":"Land."},{"key":"B9","doi-asserted-by":"publisher","first-page":"105753","DOI":"10.1016\/j.frl.2024.105753","article-title":"Can rural areas in China be revitalized by digitization?
