As China's poverty alleviation strategy transitions from addressing absolute poverty to gradually eliminating relative poverty, the intergenerational transmission of poverty within households has garnered increasing academic attention. The intergenerational transmission of relative poverty among families with disabled members in China stems from multiple factors, including insufficient economic capital, lack of human capital, inadequate social networks, and insufficient policy support. Among these, family education levels and educational attainment serve as the primary channels for intergenerational poverty transmission, while social capital and institutional factors may partially amplify or mitigate the perpetuation of poverty. Based on this analysis, this paper proposes that effective measures to break the intergenerational cycle of relative poverty among disabled individuals include strengthening the social security system for the disabled, enhancing educational support for the disabled, encouraging employment and entrepreneurship among the disabled, establishing comprehensive social assistance systems and support mechanisms, and fostering a harmonious and inclusive social and cultural environment.
