摘要
“农村义务教育学生营养改善计划”作为加快农村教育发展、促进教育公平的重要干预措施,对提高农村学生健康人力资本具有重要意义。基于中国家庭动态跟踪调查(CFPS)数据,使用双重差分(DID)和倾向得分匹配—双重差分法(PSM-DID)对政策效应进行评估,实证检验了“营养餐改善计划”对农村义务教育阶段学生身体素质的影响。研究发现,营养餐计划的执行显著提升了农村义务教育阶段学生身体素质,使体质指数BMI上升0.795个单位,体重上升约2.1斤。其中女生参与改善计划后体质指数BMI上升约0.84个单位,相比于男生高出约0.09;女生体重上升约2.4斤,比男生多增加0.45斤,计划对女生的影响更大,显著提升了女生的身体素质。
As an important policy to accelerate the development of rural education and promote educational equity,the"plan for improving the nutrition of rural compulsory education students"is of great significance in improving the healthy human capital of rural students.Based on the data of Chinese Family Panel Studies(CFPS)and using the PSM-DID method,this paper empirically tested the influence of"nutritious meal improvement plan"on the physical quality of rural compulsory education students.The study found that the implementation of the nutritious meal program significantly improved the physical fitness of rural students in the stage of compulsory education,resulting in a BMI increase of 0.795 units and a weight increase of about 2.5kg.The BMI of female students increased by 0.835 units after participating in the improvement plan,which was 0.082 higher than that of male students.The weight of female students increased by about 2.36 kg,0.45 kg more than that of male students.The plan had a greater impact on female students and significantly improved their physical quality.
