慢性病是我国国民健康最主要的威胁，构建高效率的慢性病防治体系对应对快速增长的健康服务需求和确保卫生筹资可持续意义重大。已有研究大多关注医疗卫生服务体系的技术效率，有关配置效率研究较少，特别是慢性病防治体系的配置效率评价存在空白。可避免住院费用能够反映医疗卫生服务体系的配置效率。本研究拟基于卫生费用核算体系2011框架，构建慢性病可避免住院费用核算方法，填补我国慢性病防治体系配置效率评价研究空白，并利用宏观统计数据及国家卫生费用监测点数据，开展慢性病可避免住院费用核算实证研究，验证并完善所构建方法。其次，基于安德森卫生服务利用模型，构建慢性病可避免住院影响机制模型，并利用第六次国家卫生服务调查数据及相关卫生统计数据，运用Heckman两阶段回归模型，验证并完善所构建的影响机制模型。最后，基于实证研究结果，提出减少我国慢性病可避免住院费用，改善慢性病防治体系配置效率的政策建议。

Non-communicable diseases (NCDs) have become the major threat to the health of Chinese people. Building a highly efficient NCDs prevention and treatment system is of great significance for meeting rapidly increasing health demands and ensuring health financing sustainability. Most of existent studies focus on the technical efficiency evaluation of health system, while few looking at allocative efficiency. There is a research gap in the methodology study on allocative efficiency evaluation of NCDs prevention and treatment system. Avoidable hospitalization expenditure can be used to uncover allocative efficiency issue in health system. This study aims to develop the accounting methodology of NCDs avoidable hospitalization expenditure under the theoretical framework of the System of Health Account 2011, so as to fill research gaps in allocative efficiency evaluation of NCDs prevention and treatment system. NCDs avoidable hospitalization expenditure will be estimated with data from administrative data as well as National Health Accounts Monitoring Site Data, with the purpose to examine and improve the developed accounting methodology. Moreover, this study will also establish the impacting mechanism model of NCDs avoidable hospitalization based on Anderson healthcare utilization model, and with the data from sixth wave of Domestic Health Survey in China, Heckman two-step regression model will be used to examine and improve the proposed mechanism model. At last, based on findings from empirical study, it will propose policy suggestions on reducing NCDs avoidable hospitalization expenditure and improving allocative efficiency for NCDs prevention and treatment system in China.
