摘要跨区域松散型医疗联合体(以下简称医联体)是当前长江三角洲区域(以下简称长三角)医疗服务一体化发展的重要载体。本研究采用史密斯政策执行过程模型，从理想化政策、政策执行机构、政策目标群体和政策执行环境4个维度，分析在长三角一体化发展背景下，以上海市三级公立医院为牵头单位，江苏、浙江和安徽3个省份的医疗机构为成员单位组建的跨区域松散型医联体的发展困境。经分析，跨区域松散型医联体发展政策尚未明确医联体组织管理模式、运行机制和实施路径，医联体法人治理结构不成熟；政策执行机构在专项资金支撑和相关配套政策制定方面相对滞后；政策目标群体的参与度不足及其激励机制不完善；政策执行环境存在各地医疗卫生服务规章制度不统一，各地政府卫生筹资能力不同，医疗机构管理理念协同性不足，以及信息系统缺乏统一标准等问题。基于上述困境，本研究提出应加强跨区域松散型医联体发展规划布局，健全法人治理结构；强化政府主体责任，提高政策执行能力；完善跨区域松散型医联体内部合作运行机制，提升目标群体认同感；优化政策执行环境，落实各项支持措施，为进一步推动长三角优质医疗资源的协同发展提供参考。

abstractsThe cross regional loose medical alliance is an important carrier in the current integrated development process of medical services in the Yangtze River Delta region. Smith policy implementation process model was used to analyze the development difficulties of cross regional loose medical alliances from idealized policies, policy implementation institutions, policy target groups, and policy implementation environment. Such medical alliances were formed under the background of integrated development in the Yangtze River Delta, with Shanghai′s tertiary public hospitals as leading units and medical institutions in Jiangsu, Zhejiang, and Anhui provinces as member units. Analysis showed that the policies for such medical alliances development had not yet clearly defined the organizational management mode, operational mechanism, and implementation path, and the corporate governance structure of medical alliance was immature; The policy implementation agencies were relatively lagging behind in the support of special funds and the formulation of related supporting policies; Participation of policy target groups was insufficient and their incentive mechanisms was imperfect; There were problems in the policy implementation environment, namely inconsistent medical and health service regulations and systems in different regions, different health financing capabilities of local governments, insufficient coordination of medical institution management concepts, and a lack of unified standards in information systems. Based on the above difficulties, this study proposed to strengthen the development planning and layout of cross regional loose medical alliances, and improve the corporate governance structure; To strengthen the government′s main responsibility and improving policy implementation capabilities; To improve the internal cooperation and operation mechanism of cross regional loose medical alliances, and enhance the sense of identity of the target group; To optimize the policy implementation environment and implement various support measures, so as to provide references for further promoting the coordinated development of high-quality medical resources in the Yangtze River Delta region.
