在回顾我国公共图书馆服务体系可持续发展研究现状的基础上，以广东流动图书馆为例，客观总结该模式的先进性在于其垂直化运作模式、契约化管理模式以及流动化纸质资源配置与数字资源共享机制；指出其存在问题包括：该服务体系的文化项目属性无法取代制度保障，与地方政府的契约关系约束力不强，缺乏稳定完善的财政制度与政策，缺乏科学、透明的绩效考核机制以及现代图书馆治理理念与模式等；提出建立公共图书馆服务体系治理机制的改革思路，即：确立公共图书馆服务体系的合法属性，确立公共图书馆服务体系合理的建设主体和职责，合理设置公共图书馆服务体系的委托建设主体，组建专业的公共图书馆服务体系管理委员会，建立系统完善的社会效益评估机制和监督机制等。

The paper reviews the status quo of studies on sustainable development of China public library service system with Guangdong as an example. Guangdong Mobile Libraries System excels in following aspects: the model's vertical operation mode, contract management mode, and the mobile printed resources allocation and digital resources sharing mechanisms. However, some problems exist, which include the failure of the service system's cultural project nature to replace system guarantee, not-so-strong contract binding relationship with the local government, a lack of sound and stable financial system and policies, the absence of scientific and transparent performance evaluation system, and a lack of modern library management concepts and models. Strategies are recommended as follows: establishing the legal nature of the public library service system and its management mechanism, identifying reasonable establishing actors and their responsibilities, rational set-up of commissioned establishing actors, formation of a professional management commission as well as a sound and systematic social evaluation and supervision mechanism.
