我国城乡居民卫生服务需求的收入弹性分析:基于非线性STR模型

Analysis on Urban and Rural Residents' Income Elasticity for Health Care Demand in China:Based on the Nonlinear STR Model

目的:研究我国城乡居民卫生需求收入弹性的非线性特征。方法:基于平滑过渡(STR)模型分析不同阶段我国城乡居民卫生需求收入弹性的变化。结果:对城市居民来说,卫生需求收入弹性适用于LSTR2模型;对农村居民来说,卫生需求收入弹性适用于LSTR1模型。结论:我国城乡居民卫生服务需求的收入弹性都大于1。

Objective： To study the nonlinear income elasticity dynamics for health care demand of urban and rural residents in China. Methods： Using the STR model to analyze the changes of income elasticity for health care demand of urban and rural residents in different periods in China. Results： The LSTR2 model could be applied to study the income elasticity for urban residents＇ health care demand, and the I,STRI model could be applied to study the income elasticity for rural residents＇ heahh care demand. Conclusion： For both urban residents and rural residents, the income elasticity of health care demand was beyond 1.
