Unlike difference in differences approaches, this method can account for the effects of confounders changing over time, by weighting the control group to better match the treatment group before the intervention. Another advantage of the synthetic control method is that it allows researchers to systematically select comparison groups. It has been applied to the fields of political science, health policy, criminology, and economics.

【翻译】合成对照方法是一种统计方法，用于评估比较案例研究中的干预措施的效果。它使用多组数据加权组合构建对照组，并与治疗组进行比较。这种比较被用来估计如果治疗组没有接受治疗会发生什么。与双重差分（Difference in difference）方法不同，这种方法可以纳入随时间变化的混杂因素的影响，通过调整对照组的加权系数，能更好地对干预前的治疗组数据进行匹配。合成对照的另一个优点是，它允许研究人员在多组候选数据中做系统性选择。它已应用于政治学、卫生政策、犯罪学和经济学等领域。

综合控制方法结合了匹配技术和差中差技术的要素。差异中的差异法是一种常用的政策评估工具，用于在总体水平上评估干预措施的效果(例如:。州、国家、年龄组别等)平均超过一组未受影响的单位。著名的例子包括新泽西州快餐店提高最低工资对就业影响的研究，比较对象是紧邻州边境的费城，那边的快餐店没有受到提高最低工资的影响，以及研究南部城市的犯罪率来评估马里埃尔移民潮对犯罪率的影响。在这个特定的场景中，控制组可以被解释为一个加权平均数，其中一些单位实际上得到了零重量，而其他单位得到了相等的，非零重量。

The synthetic control method is a statistical method used to evaluate the effect of an intervention in comparative case studies. It involves the construction of a weighted combination of groups used as controls, to which the treatment group is compared.[1] This comparison is used to estimate what would have happened to the treatment group if it had not received the treatment. Unlike difference in differences approaches, this method can account for the effects of confounders changing over time, by weighting the control group to better match the treatment group before the intervention.[2] Another advantage of the synthetic control method is that it allows researchers to systematically select comparison groups.[3] It has been applied to the fields of political science,[3] health policy,[2] criminology,[4] and economics.[5]

Imposing some structure

and assuming there exist some optimal weights [math]\displaystyle{ w_2, \ldots, w_J }[/math] such that

[math]\displaystyle{ Y_{1t} = \Sigma^J_{j=2} w_{j}Y_{jt} }[/math]

for [math]\displaystyle{ t\leqslant T_{0} }[/math], the synthetic controls approach suggests using these weights to estimate the counterfactual

[math]\displaystyle{ Y^N_{1t}=\Sigma^J_{j=2}w_{j}Y_{jt} }[/math]

for [math]\displaystyle{ t\gt T_{0} }[/math]. So under some regularity conditions, such weights would provide estimators for the treatment effects of interest. In essence, the method uses the idea of matching and using the training data pre-intervention to set up the weights and hence a relevant control post-intervention.[8]
