individual_patents_t81 <- read_dta("D:/Rdata/data/individual_patents_t81.dta")

table8<-list(
  result1 <- lm(patented ~ treated_post+treated+post,
              data = individual_patents_t81[individual_patents_t81$appyr>=1995,]),
  result2 <- lm(patented ~ treated_post+treated+appyr96+ appyr97+ appyr98+ appyr99+ appyr00+appyr01+ appyr02+ appyr03+appyr04+ appyr05+ appyr06+ appyr07+appyr08+ appyr09+ appyr10,
              data = individual_patents_t81[individual_patents_t81$appyr>=1995,]),
  result3 <- plm(patented ~ treated_post+treated+appyr96+ appyr97+ appyr98+ appyr99+ appyr00+appyr01+ appyr02+ appyr03+appyr04+ appyr05+ appyr06+ appyr07+appyr08+ appyr09+ appyr10|id_npo,
               data = individual_patents_t81[individual_patents_t81$appyr>=1995,],
               effect = 'individual',
               model = 'within'),
)
数据本身的不大，但是观测值有10多万，没有加“|id_npo”可以跑出来，加了跑不出来。
