中国公共卫生财政支出动态特征研究——基于拉格朗日乘数单位根检验的实证分析

文章利用中国1991-2010年混合横截面数据和时间序列数据,探讨了公共卫生支出与收入、与收入无关的其他因素之间的关系。为研究这些变量的平稳性,不使用渐近正态分布临界值,而运用Bootstrap方法所得出的有限样本临界值进行体现结构性变化的LM单位根检验。研究的一个重要结论是,政府预算赤字对中国的公共卫生支出存在着长期显著影响。这为中国富裕和贫困地区在公共卫生财政政策以及卫生服务覆盖范围之间的显著差异方面提供了支持证据。

The Stationarity of Regional Fiscal Expenditure of Public Health in China: Evidence from LM-type Unit Root Tests

In this paper, mixed cross-sectional data and time series data are employed to explore the relationship between public health expenditure and income as well as other factors which have nothing to do with income in China from 1991 to 2010. In order to study the stationarity of these variables, this paper does not use the critical value of the asymptotic normal distribution, but conducts panel LMunit root tests to reflect the structural changes using finite sample critical values obtained by the Bootstrap method. It is an important conclusion that the government budget deficit can exert long-term significant impact on public health expenditures. So, this paper provides supporting evidence on significant difference in the fiscal policy of public health as well as the health service coverage between rich and poor areas.
