疫苗接种社会许可的社会生态治理框架与助推干预：行为公共管理视角下的混合方法研究

接种疫苗是迄今最成功的公共卫生措施之一。疫苗拒绝和犹豫阻碍免疫计划推进，被WHO列为全球健康十大威胁。既往研究多关注消解负向疫苗信念，受行为经济学和积极心理学启迪，选题提出疫苗社会许可概念，目的是以最小成本增进“个体接纳疫苗的正向心理力量”，它与疫苗犹豫共同建构一个连续性疫苗信念图谱。执行量表开发程序，编制疫苗社会许可心理前因的测量工具；通过离散选择实验，识别个体疫苗的选择偏好；提出疫苗社会许可社会生态因素模型并解释其层级结构属性，采用组态分析方法检验因素引发疫苗社会许可的因果关系；基于上述结果，建构心理前因、选择偏好及社会生态三维决定因素模型，选择其中六组子要素，进行行为助推方案设计及实验。最后，在治理七要素下提出疫苗社会许可的社会生态治理建议以及激励行为者、资源扩容和优化制度的三维行动清单。在概念创新、理论建立及干预策略上，选题可推进疫苗认知与行为在公共健康治理领域的学术和实践。

The vaccination is the most successful public health initiatives to date. Vaccine rejection and hesitation regarded as the top threats to global health by WHO, which has severely prevent vaccination due to its prevalence. Previous study focused on how to eliminate negative vaccine belief. Inspired by the frameworks and theories in Behavioral Economics and Positive Psychology, to increase individual positive psychological power for vaccine acceptance with a minimal cost, the current study will firstly propose vaccine social license, which can jointly build a continuous spectrum of vaccine belief with vaccine hesitancy. The current study will develop a measuring tool of psychological antecedents of vaccine social license by performing a strict procedure. The current study will identify individual choice preference by carrying out a Discrete Selection Experiment. A social-ecological factors model of vaccine social license will be proposed and its hierarchical structure also be illustrated. Causal relationship between factors group and increasing vaccine social license will be tested by configuration analysis method. Base on a building three-factor determinate model including choice preference, psychological antecedents and social-ecological factors, a behavioral nudge scheme design which includes six elements above will be performed. Last, the study will put forward a policy proposal of social ecological governance that includes seven elements of governance and three-dimensional action list for agent motivator, resource capacity and institutional optimization. Due to the effort at the concept formulation, theory establishment and intervention strategy proposal, the study tends to contribute to propel academic and practical double harvest at aspect of vaccine cognition and behavior in the fields of public health and governance.
