Rare earth luminescence has attracted widespread attention for several decades, among which nearinfrared(NIR) light-related up-conversion luminescence and NIR-Ⅱ luminescence are widely used in the biomedical field. The NIR-related luminescence is widely studied due to the excellent performance, such as good biocompatibility, deep tissue penetration depth, low self-fluorescence and minimal light damage to organisms. In this review, we mainly introduce the mechanism for rare earth up-conversion luminescence, NIR-Ⅱ luminescence and conclude their advantages compared with traditional *** excellent priorities provide the basis for NIR-related luminescence bioimaging in vivo. Additionally,we hilglight the scheme for the sensitive detection of substances in organisms and various methods for biological therapy. In spite of the existing research, it is outlined that NIR-related luminescence has great potential to be applied in different aspects, expanding perspectives and future challenges of research in related fields. Based on the current scientific achievements, this review can provide reference for research in the areas mentioned above, expand the research direction and arouse a broad interest in different disciplines to pay attention to rare earth luminescence.

动态制度变迁中的学习行为是新制度经济学的重要议题。目前学界对学习理论如何服务于制度研究的机制尚不明确,难以揭示学习行为对制度变迁的影响路径。文章基于文献综述的研究发现:学习理论通过促使制度变迁的微过程实例化和辅助进化思想描绘动态特征两种机制,补充制度理论。学习行为通过三种路径影响制度变迁:学习类型的一些概念能够解释制度内生性,引入学习行为的制度研究有助于分析多层次互动,以及可以将行为与制度的协同演化特征具体化。诺斯、斯泰因、葛拉克、钱德勒等人的动态模型对学习行为的引入由浅入深,一致肯定了学习行为对主体认知的塑造作用及对制度变迁的决定性作用。一个完整的包含学习行为的制度分析框架应该既包括多层次互动又蕴含协同演化思想,前者可以整合自下而上和自上而下两个方向的制度变迁,后者能够实现微观行为与宏观制度之间的交织与相融。
