你得看人家实际用的什么模型啊

您好！这篇paper写的是它用的a pooled time-series cross-sectional regression，然后他的
因变量的角标是i,t-s
自变量的角标是i，t
控制变量的角标也是i,t-s
s=1,2,3,4,5
想请问您一下这是怎么个回归顺序呀

把相关的页面和模型描述发出来吧。你就这么说我也不是很清楚。

"A data base that provides a multivariate statistical history for each of a number of individual entities is called a pooled cross-sectional and time series data base in the econometrics literature. In marketing and survey literature the terms panel data or longitudinal data are often used. In management science a convenient term might be management data base."
所以，应当就是面板数据
