所以,在该实例中,可以得到结论:该新政策对指标y并没有显著效果。 Python实现 事实上,有了多组period、treat、did和y值之后,要计算\beta,本质就是一个最小二乘法的优化问题。 只不过此处,还需要求解p值。 庆幸的是,该功能并不需要自己编写代码去实现,可以调用statsmodels工具包来求解。 以下为Python计算\beta值...
双重差分模型(Differences-in-Differences,DID),其常用于政策评估效应研究,比如研究‘鼓励上市政策’、‘开通沪港通’、‘开通高铁’、‘引入新教育模式’等效应时,分析效应带来的影响情况。 比如:两类地区A和B,在2020年A类地区没有开通高铁,B类地区没有开通。那么开通高铁对于GDP的影响情况如何呢? 涉及两个关键数据...
