中文摘要
现有关于营养改善项目的研究主要集中在其短期效果。本文利用2019年中国家庭金融调查（CHFS）数据，系统探讨了农村中国普遍推行的学校营养改善计划（NIP）对学生教育成就的长期影响、潜在机制及其成本效益。研究结果显示，NIP显著增加学生上高中的概率，促进其升入大学，并延长其受教育年限。这些结论在各种稳健性检验中均保持稳健。NIP通过改善学生的健康状况、认知能力、非认知技能，以及提升家长的教育期望，进而提升学生的教育成就。此外，受到影响最大的群体是父母受教育水平较低和来自西部地区的学生。成本-收益分析表明，NIP的经济回报超过其成本，彰显了其显著的经济效率。该研究强调了学校营养计划作为人力资本投资的重要性，并为中国及其他发展中国家制定政策以应对教育不平等、改善公众健康和福祉提供了宝贵的洞见。
英文摘要
Existing research on nutritional assistance largely focuses on its short-term effects. Using data from the 2019 China Household Finance Survey (CHFS), this research investigates the long-term effects, underlying mechanisms, and cost-effectiveness of the Nutrition Improvement Program (NIP), a widespread school meal program in rural China, on students’educational attainment. Our findings indicate that the NIP significantly increases the likelihood of students attending high school and college and extends their years of education. These results are robust across various sensitivity tests. The NIP improves educational attainment by enhancing students’health, cognitive abilities, non-cognitive skills, and parental educational expectations. Furthermore, the impact is more pronounced among students with lower parental education levels and those in western regions. A cost-benefit analysis shows that the economic returns of the NIP surpass its costs, highlighting its substantial economic efficiency. This research underscores the importance of school meal programs as a human capital investment and provides valuable insights for policymakers in China and other developing nations seeking to address educational inequality and improve population health and well-being.
