In response to the “Three-All Education” agenda and persistent shortcomings in university financial aid practice—such as an overemphasis on disbursement over development and outcomes over process—this study focuses on aviation-oriented higher vocational colleges. Considering the sector’s strong safety culture, high costs associated with training and certification, and close industry–education integration, the paper develops an analytical framework of elements–mechanisms–pathways and proposes an integrated “one-body, three-dimensions” model that shifts student support from basic hardship relief to development-oriented empowerment. Centered on students’ holistic development, the model operates through multi-actor collaboration, whole-process alignment, and multi-context integration, supported by collaborative, precision, and developmental mechanisms. It enables a closed-loop operation linking financial aid with talent development, student affairs, career services, and school–enterprise partnerships, underpinned by institutional arrangements, resource integration, and a smart digital platform.
