摘要(Abstract)：

近年来，作为最重要的准实验方法之一，断点回归设计(RDD)在经济学研究中的重要性不仅体现在应用实践中的快速发展，更体现在一系列前沿理论的突破与完善。本文系统梳理了连续性和局部随机性两种断点回归设计的分析框架，总结了两种框架的关键假设、估计方法、统计推断、实现方式及主要操作步骤，在此基础上对比了两者在理论和应用场景方面的差异。本文进一步阐述了多重配置变量、多重断点和拐点回归设计等三种特殊情形下的RDD估计方法，并提供了具体的实现方式，为丰富RDD方法的应用场景、拓展实证研究的可行性提供了有力支撑。

关键词(KeyWords)： 断点回归设计;连续性框架;局部随机性框架;理论进展;应用场景
