By using Data Envelopment Analysis approach, we treat the health production system in a certain province as a Decision Making
Unit (DMU), identify its inputs and outputs, evaluate its technical efficiency in 1982, 1990 and 2000 respectively, and further
analyze the relationship between efficiency scores and social-environmental variables. This paper has found several interesting
findings. Firstly, provinces on frontier in different year are different, but provinces far from the frontier keep unchanged.
The average efficiency of health production has made a significant progress from 1982 to 2000. Secondly, all provinces in
China can be divided into six categories in terms of health production outcome and efficiency, and each category has specific
approach of improving health production efficiency. Thirdly, significant differences in health production efficiencies have
been found among the eastern, middle and western regions in China, and among the eastern and middle regions. At last, there
is significant positive relationship between population density and health production efficiency but negative relationship
(not very significant) between the proportions of public health expenditure in total expense and efficiency. Maybe it is the
result of inappropriate tendency of public expenditure. The relationship between abilities to pay for health care services
and efficiency in urban areas is opposite to that in rural areas. One possible reason is the totally different income and
public services treatments between rural and urban residents. Therefore, it is necessary to adjust health policies and service
provisions which are specifically designed to different population groups.

This paper investigates the causal impact of large unexpected windfalls on individual mental health, physical health, as well as health behaviors. I use a large individual-level panel data set of lottery winners from Germany between the years 2000 and 2011 and observe lottery winners before and after winning a large lottery prize. Mental health declines immediately after winning a large lottery prize for individuals with low education and low levels of financial literacy. While these individuals report being happier after winning the lottery, evidence from commonly used SF-12 measures of mental health indicates that winners with low education experience increased role limitations due to emotional problems, are more anxious, and have less energy after their win. The impact on various measures of mental health is highly robust, statistically significant, economically significant, and persists for up to two years after the win. Unexpected windfalls have no impact on the mental health of individuals with high education or high financial literacy. Winning the lottery has no impact on individuals’ health behaviors such as smoking or alcohol consumption, and it has no impact on doctor visits, hospital stays, or illness-related work absences regardless of education level. 相似文献

我国城乡居民健康公平性研究 总被引:10,自引:0,他引:10
本文采用历史的、比较的分析方法,运用基尼系数、洛伦茨曲线等分析工具,分别从筹资公平、服务提供公平和健康公平三个方面对我国城乡居民健康公平问题进行了定性与定量分析,得出了新型农村合作医疗制度的开展显著降低了城乡卫生服务筹资的基尼系数等一系列结果.根据研究结果,对城乡健康公平性与二元社会结构,与政府干预、市场调节之间的关系作了分析,并对提高城乡健康公平性提出了相关政策建议. 相似文献
