Does chairpersons’ having sisters affect corporate green technology innovation performance?

Purpose This study aims to examine whether a chairperson’s having sisters impacts corporate green innovation performance. Design/methodology/approach The study sample has 627 Chinese non-stated-owned enterprises. Using the OLS regression controlling for year and industry fixed effects, the empirical results support the research hypothesis. Findings Compared with chairpersons who have brothers only, firms whose chairpersons have sisters produce higher output on green innovation. That is, there is a “sister effect” in corporate green technology innovation. The more sisters, the higher output on corporate green innovation. Originality/value The authors contribute to the “culture and finance” research paradigm by examining the effect of the gender of chairpersons’ siblings on corporate green technology innovation performance.
