【摘要】：隨著農(nóng)村勞動(dòng)力的大規(guī)模轉(zhuǎn)移,農(nóng)村內(nèi)出現(xiàn)了大量的留守兒童。許多學(xué)者都非常關(guān)注父母外出對(duì)兒童健康的影響問(wèn)題,但是大量的實(shí)證分析都未考慮到樣本的選擇性偏差,因而得出了并不準(zhǔn)確的結(jié)論。本文使用PSM方法,在控制樣本選擇性偏差的情況下得出了如下研究結(jié)論:在兒童生長(zhǎng)遲緩發(fā)生率方面,相比于非留守兒童,留守兒童的生長(zhǎng)遲緩發(fā)生率在1%水平上低0.05%;在消瘦率方面,在5%水平上低出0.0317%;在患病率方面和腹瀉率方面,分別在1%和5%水平上低為0.0347%和0.0473%。因此,長(zhǎng)期來(lái)看,徹底解決留守兒童營(yíng)養(yǎng)健康問(wèn)題的方法和解決經(jīng)濟(jì)二元體制和城鄉(xiāng)差異的方法在本質(zhì)上是相同的,即積極推進(jìn)農(nóng)民工的城市融入,讓農(nóng)民逐漸轉(zhuǎn)變成為城市居民,從而減少農(nóng)村留守兒童的數(shù)量和規(guī)模。
[Abstract]:With the large-scale transfer of rural labor force, a large number of left-behind children appear in the countryside. Many scholars are very concerned about the impact of parents' going out on children's health, but a large number of empirical analysis did not take into account the selectivity bias of the sample, so the conclusion is not accurate. In this paper, the PSM method is used to control the selectivity deviation of samples. The following conclusions are drawn: compared with the non-left-behind children, the incidence of growth retardation in children is higher than that in non-left-behind children. The incidence of growth retardation in left-behind children was 0. 05% at the level of 1%. In terms of emaciation rate, it was 0.0317% lower than that at 5% level, 0.0347% and 0.0473% at 1% and 5% level, respectively. Therefore, in the long run, the methods for thoroughly solving the nutritional and health problems of children left behind and for solving the dual economic system and the differences between urban and rural areas are essentially the same, that is, to actively promote the urban integration of migrant workers. To gradually transform farmers into urban residents, thereby reducing the number and size of children left behind in rural areas.
