公共图书馆服务效率的提升直接关乎着现代公共文化服务体系的建设。以空间作为切入点，运用超效率SBM模型对我国31个省(自治区、直辖市)从“十一五”到“十三五”时期的公共图书馆服务效率进行测算，利用地理探测器，定量剖析图书馆服务效率的时空演化特征，深入探究其影响因素与影响机制。研究表明：(1)“十一五”以来我国公共图书馆服务效率总体水平一般，31个省(自治区、直辖市)的服务效率大体可以分为5个等级。(2)公共图书馆服务效率存在明显的空间异质性，受经济发展水平、居民受教育水平、财政分权、城镇化水平、设施网络、图书馆活跃度和队伍建设等因素的影响。其中“十一五”时期影响服务效率的因素主要包括经济发展水平、财政分权和图书馆活跃度；“十二五”时期的影响因素在“十一五”的基础上新增加了设施网络；“十三五”时期则在“十二五”的基础上，新增加了居民受教育水平、城镇化水平和队伍建设。(3)我国公共图书馆服务效率的空间分异是由政策制定与财政保障、人才引进与结构调整、社会保障与社会公平、结构转型与功能拓展、设备管理与网络运行、活动管理与活动创新六元影响机制不断循环作用的结果。

区域旅游发展与空气质量之间的关系具有复杂性。综合利用脉冲响应模型、双变量空间自相关、地理探测器等分析方法，揭示中国大陆空气污染与旅游经济的时空动态关系及影响机理。主要结论有：首先，2000-2016年中国大陆旅游业发展与空气污染的“库兹涅茨”曲线总体上不显著，空气污染与旅游经济并非简单的负向线性关系。一方面，从脉冲响应的分析结果看，与烟(粉)尘排放量对旅游经济的冲击并非完全负向的；另一方面，空气污染与旅游经济的全局空间自相关指数大部分时段为正值，并且局部空间自相关指数显著性个数较少。其次，空气污染与旅游经济的时空关系具有复杂性，主要原因是中国大陆旅游经济发展不充分、不均衡的客观实际，可能会“消化”空气污染对旅游经济的负向影响。在影响区域旅游经济增长的动力机制中，空气污染不是主导因素。第三，双变量ESDA及地理探测器分析结果为区域旅游高质量发展提供了理论指导，空气污染与旅游经济的时空关系，本质上反映的是旅游经济增长动力机制问题，区域旅游高质量发展需要重视系统中的“合力”因素及单个核心要素。未来中国旅游经济高质量发展需要在提升空气质量的同时，进一步夯实地区经济基础、规范市场化制度、调整产业结构、完善基础设施。
