利用中国营养与健康调查数据,以18岁及以上的农村居民为研究对象,通过建立联立方程回归模型,根据模型的回归系数应用夏普里值分解方法,对我国农村居民健康的收入增长效应和收入分配效应进行实证研究.研究结果显示,收入与收入差距对农村居民的健康产生了不同影响;随着收入的增长,收入差距也在不断扩大,农村居民健康的收入分配效应起主导作用,过多地挤占了健康的收入增长效应.为了促进农村居民健康福利改善,在努力提高农村居民收入的同时,政府应注重遏制农村内部收入差距和城乡收入差距扩大的趋势.
With the data collected by China Health and Nutrition Survey over the years and rural individuals agedabove 18 as the research objects,and based on the establishment of a simultaneous equation regression model,theShapley value decomposition method was applied to analyzing the unequal effects the health of rural residents byincome growth and income distribution. The empirical evidence demonstrated that:the different effects on thehealth of rural residents are exerted by income and income distribution gap. With the growth of income,the in-come inequality is also expanding,and the income distribution effects on the health of rural residents play a lead-ing role,crowding out the growth effects on the health of rural residents. This study showed that while focusing onthe role of income growth effect,we need to make more effort to check the ever-expanding of the internal incomegap among rural residents and the rural-urban income gap.
