Life expectancy of residents in Qidong,China,1975-2004;
启东市居民30年预期寿命分析
This paper used the life expectancy to reflect health status of residents and applies coefficient of variation,rate of extreme gap and Theil index to analyse the regional differences of health of the inhabitants.
采用预期寿命来反映居民健康水平,应用变异系数、极值差率和泰尔指数等方法考察我国居民健康水平的地区差异变动,同时按不同区域对泰尔指数进行了分解,从而考察了居民健康水平地区差异的构成,最后对我国居民健康水平的地区差异进行了σ收敛和β收敛检验。
