Note: the estimation sample includes 285 prefecture level and above cities in China. The sample period is from 2005 to 2018. Dependent variables are indicated by column titles in italics. ,,, and are the number of green utility model patent applications, the number of green invention patent applications, the number of green utility model patents granted, and the number of green invention patents granted. HSR and all control variables are controlled and lagged by one year in all regressions. All regressions include city fixed effects and year fixed effects. Robust standard errors in parentheses are clustered at the city level. The symbols ,, and indicate significance at the 1%, 5%, and 10% levels, respectively.
