For the career development of chief executive officers (CEOs), the existing literature lacks research from the perspectives of gender and the environment. Starting with the perspective of the environment, and through the adoption of the World Bank Survey Data on Chinese Enterprises and China's Comprehensive Social Survey (CGSS), this paper addresses the question: "Why do companies choose female CEOs?" The analysis examines 15 aspects, including enterprise scale, age, industry, owner, product market, market environment, city level, etc. The research findings are as follows. (1) The corporate environment has an impact on CEO gender, and there are differences in its nature and the degree of impact. Enterprise size, state-owned shareholding, radiation effect, market environment, and gender culture have a significant negative impact on female CEOs, while product features, industry characteristics, and female owners have a significantly positive impact on female CEOs. (2) In terms of the impact mechanism, the impact of the meso-environment on female CEOs is significantly adjusted by the macro-environment.

Therefore, the environment is the key to understanding companies recruiting female CEOs and breaking through the existing theories. In summary, we should study the gender of CEOs from the perspective of corporate environment, namely: how does the environment affect the gender of CEOs? The answer to this question will help us better understand and evaluate female CEOs and promote sustainable enterprise development.In view of the factors affecting CEO genders, scholars have carried out research regarding women's own features [1], company characteristics [2], industry environment [3], cultural differences [4], and other different perspectives, and have drawn many useful conclusions. These studies have both strengths and shortcomings. First of all, there is a hypothesis behind previous studies that males have stronger management ability than their female counterparts. However, gender is a kind of social construction, and gender culture has a profound impact on the viewpoints toward males and female...
