We utilise IBM's Watson Personality Insights service to infer chief executive officers' (CEOs') Big Five personality traits and examine whether CEO extraversion, an important personality trait associated with assertive behaviour, decisive thinking, and desire for social engagement, is associated with firms' corporate social responsibility (CSR) practices. Using a longitudinal dataset of Standard & Poor 500 firms for 2008–2016, we find that firms led by extraverted CEOs' experience higher CSR performance (both environmental and social), even after controlling for other personality traits and other CEO- and firm-specific characteristics. In addition, we find that the relationship between CEO extraversion and CSR performance is more pronounced among industries with higher environmental impact. Consistent with upper echelons theory, our results suggest that firms' strategic environmental and social decisions are significantly influenced by the personal characteristics of corporate executives.

高管个性与可持续性：外向的首席执行官是否会提高企业的社会责任感？

我们利用 IBM 的 Watson Personality Insights 服务来推断首席执行官 (CEO) 的大五人格特质，并检查 CEO 外向性（一种与果断行为、果断思维和社会参与愿望相关的重要人格特质）是否与公司的企业社会责任 (CSR) 实践。使用标准普尔 500 强公司 2008 年至 2016 年的纵向数据集，我们发现由外向型 CEO 领导的公司具有更高的企业社会责任绩效（包括环境和社会），即使在控制其他人格特征和其他 CEO 和公司具体的特点。此外，我们发现 CEO 外向性与企业社会责任绩效之间的关系在环境影响较大的行业中更为明显。
