双重差分估计
双重差分模型(difference-in-difference,DID)近年来多用于计量经济学中对于公共政策或项目实施效果 的定量评估。
通常大范围的公共政策有别于普通科研性研究,难以保证对于政策实施组和对照组在样本分配上的完全随机。非随机分配政策实施组和对照组的试验称为自然试验(naturaltrial),此类试验存在较显著的特点,即不同组间样本在政策实施前可能存在事前差异,仅通过单一前后对比或横向对比的分析方法会忽略这种差异,继而导致对政策实施效果的有偏估计。(Quantitative evaluation of policy or project implementation effect. Generally, a wide range of public policies is different from general scientific research, and it is difficult to ensure that the sample allocation for the policy implementation group and the control group is completely random. The non-randomly assigned policy implementation group and the control group are called natural trials, which have significant characteristics, i.e. there may be prior differences between the different groups of samples before the implementation of the policy, and this difference will be ignored only through a single pre-and post-comparison or horizontal comparison analysis method, which leads to the policy. Biased estimation of implementation)
