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.
