国家经济发展水平对居民健康支出的影响可能存在非线性的影响。基于2002~2012年31个省际数据,采用面板门槛模型实证检验政府卫生支出在经济发展水平对居民健康支出的影响中是否存在门槛效应。研究结果显示,总体上经济发展水平对居民健康支出具有促进作用,但是随着政府卫生支出的增加,人均GDP对居民健康支出的影响存在三重门槛效应;不同省际间政府卫生支出存在差异,这也是造成不同省际居民健康支出差异的原因。
The impact of national economic development on residents’ health expenditure may have a nonlinear effect. Based on the 31 provincial data from 2002 to 2012, panel threshold model was used to empirically test whether the government health expenditure has a threshold effect on the health expenditure of residents due to the level of economic development. The results show that, overall, the level of economic development has a positive effect on residents’ health expenditure. However, with the increase of government health expenditure, there is a triple threshold effect of per capita GDP on the health expenditure of residents. There are differences in government health expenditure among different provinces, It is also the reason for the difference in health expenditure among residents in different provinces.
