Human Capital Development Before Age Five: An Assessment of Early Investment and Intervention 五岁前的人力资本发展：早期投资与干预评估 Human Capital First 5 Years This research report delves into the profound impact of early childhood environment before age five on adult health, education, and economic achievement. Using economic models, the authors demonstrate that while negative shocks in early life are not irreversible, their effects are often more significant than fluctuations during adolescence. The report compiles extensive empirical data on birth weight, environmental pollution, mental health, and family income, proving the necessity of early intervention. The study focuses on assessing the actual remedial effects of policies such as Head Start, WIC nutrition subsidies, expanded health insurance, and home visits. Although children from impoverished families are more vulnerable to early harm, high standards of early childhood education and economic support can effectively mitigate these adverse effects. In conclusion, because investments at different stages of childhood are complementary, early human capital investment has extremely high long-term returns.
