This study extends previous literature on the association between Confucianism and corporate decisions by examining Confucianism’s influence on board gender diversity. Using a sample of Chinese listed firms during the period of 2001–2011 and geographic-proximity-based Confucianism variables, I provide strong and consistent evidence to show that Confucianism is significantly negatively associated with board gender diversity, suggesting that the proportion of women directors in the boardroom is significantly lower for firms surrounded by strong Confucianism atmosphere than for firms located in regions (...) with weak Confucianism atmosphere. This finding also implies that Confucian philosophical system has important impacts on business ethics and women’s status in corporate governance. Moreover, GDP per capita, the proxy for economic development level in a province in which a firm is located, attenuates the negative association between Confucianism and board gender diversity. Above results are robust to different measures of Confucianism and board gender diversity and are still valid after controlling for the potential endogeneity between Confucianism and board gender diversity.
