摘　　要：在"健康中国"战略背景下,探讨农村内部医疗保健消费不平等及其与收入的关系具有重要的现实意义。基于中国健康与营养调查(CHNS)2004-2011年数据,本文利用Heckman样本选择模型和夏普里值分解方法实证分析了中国农村居民收入对医疗保健消费的影响效应。研究发现:医疗保健消费的收入弹性系数为0.118,表现为缺乏弹性。2004-2011年中国农村居民医疗保健消费不平等保持在较高水平,基尼系数均超过0.8,其中收入的贡献介于10%-13%之间,且在所有因素中其重要性排在第四、五位。这一结论在不同的不平等指标下依然稳健。Under the background of"Healthy China"strategy,it is of great practical significance to explore the inequality of healthcare consumption in rural areas and its relationship with income.Based on the CHNS data from 2004 to 2011,we positively analyze the effect of residents?income on health expenditure in rural china by using Heckman sample selection model and Shapley value decomposition.The result shows that the income elasticity of health expenditure is 0.118 and inelastic.The healthcare expenditure inequalities are about 0.06-0.1(Gini Coefficient)in 2004,2006,2009,and 2011.Income explains between 10 to 12 percent of the total healthcare expenditure inequality and ranks the fourth or fifth largest contributor.This conclusion is still robust under different inequality indicators.
