Research on the socioeconomic factors that influence the development of voluntary, non-remunerated blood donation in China-A correlation and regression analysis based on data from 2012 to 2018.

City characteristics and demographics significantly impact blood donation rates in different ways. A universal policy may have limited effect given the heterogeneity across cities. Tailored interventions targeting specific city clusters and education levels are needed to promote blood donation behavior, especially among youth and students. Investment in education and targeted education on blood donation appear particularly impactful. A combined approach integrating social and economic policies will likely be most effective.
