在Stata中,随机种子是一个用来初始化伪随机数生成器的数值。伪随机数生成器用于生成随机数,但实际上是通过确定性算法计算得出的。通过设置随机种子,可以确保每次运行程序时生成的随机数序列是一致的,这对于实验的可重复性和结果的可验证性非常重要。 在Stata中,你可以使用`set seed`命令来设置随机种子,例如: ```...

图2给出了95%置信区间的估计系数。 横轴为碳价格稳定机制(CPSM)实施前后的年数,例如6和-6分别代表CPSM实施前6年和实施后6年。 可以接受CPSM实施前CPSM地区和非CPSM地区TFP时变趋势一致的原假设,平行趋势假设可接受。 可以将CPSM的实施作为一个准自然实验来考察CPSM对企业层面全要素生产率(TFP)的影响。 还可以发...
