断点回归设计:理论前沿进展与新应用场景Regression Discontinuity Design:Theoretical Developments and Extended Applications
刘冲,诸宇灵,李皓宇
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。
