Despite efforts to improve national health levels, inequalities in health have endured in China. Most prior studies have been conducted from the perspective of influencing factors with respect to regional differences or focus on comparative analyses of health development levels. This paper reviews regional characteristics to examine dynamic changes in health levels within regions, measures and distinguishes inter-regional differences, and explores the evolution of these differences. Results show that elderly health levels in the overall system are polarized to varying degrees, but within regions, agglomeration continues. There were decreasing fluctuations in overall differences during the sample period: Regional differences influenced fluctuations the most, and inner-regional differences the least. In the short term, inequalities in health will continue to exist, but the gap has been closing in the long-term in China. The health development of neighborhoods has a significant driving effect in narrowing the differences in the eastern and northeast regions, while economic and health security levels in the central and western regions should be strengthened. These findings can help decision-makers to create appropriate health policies that are more targeted to actual needs, and provide policy implications for promoting the development of better life quality in China by considering regional differences.Sustainability 2020, 12, 2288 2 of 15 of social inequality, increased health inequality damages overall social welfare. In particular, with China's increasingly severe problem of aging, how to provide fair and equal health care services for the disadvantaged elderly is of great significance to the "Healthy China Strategy 2030". Researchers have found that regional health differences still exist. Most of the prior literature has focused on health-influencing factors or on descriptive analyses, while systematic and in-depth studies on dynamic changes in health levels and evolutionary trends in regional differences are lacking. In this paper, we focus on regional health characteristics to investigate the dynamic changes in regional health levels and the evolution trends of regional health differences. The study not only provides a clear outline for decision makers to learn the characteristics associated with regional health in China, but can also aid in the evaluation of existing policies and health services to provide a practical reference for balancing elderly health levels (EHLs) between cities and regions. Studies on regional health inequality began in 1970s. In 1977, the British government formed the "Health Inequality" research group, and in 1980, this group submitted a report to the British Parliament to document health inequalities in society. This report generated widespread concern over health inequality, and thereafter, many subsequent studies have addressed the relationship between health differences and social economy. Mackenbach [1] and Doorslaer [2-4] measured the health levels and mortality rates among diff...
