PurposeIn recent years, the phenomena of “accelerating” and “jumping” during the international expansion of Chinese enterprises have attracted a lot of attention from scholars. However, while a CEO’s career horizon can significantly affect his or her enterprise’s strategic decision-making, few studies have explored the role of CEO career horizon in terms of “accelerating” and “jumping” internationalization.Design/methodology/approachBased on a sample of China’s A-share listed manufacturing companies from 2008 to 2017, this study explores the impact of CEO career horizon on the internationalization pace and international rhythm of enterprises.FindingsFirst, the shorter the CEO’s career horizon, the more likely the CEO can avoid risky strategic decisions, which ultimately causes a negative relationship between CEO career horizon and the internationalization pace and rhythm of the enterprise. Second, for larger and older boards of directors, there is a more negative impact of the CEO’s short-term career horizon on the internationalization pace and internationalization rhythm of the company. However, given a larger proportion of female directors and non-executive directors, the CEO’s short-term career horizon has a weaker negative impact on international pace and the rhythm of internationalization.Originality/valueFirst, based on upper echelon theory, this study interprets the influence of CEO career horizon on the time dimension of corporate internationalization (including internationalization pace and international rhythm), deepening the theory’s explanatory power. Second, by clarifying the important predictive effect of CEO career horizon on internationalization pace and international rhythm, this research enriches extant research on both variables’ antecedents, as well as that on the influence of CEO career horizon. Finally, by introducing the regulatory role of the board’s supervisory ability, this study clarifies the boundary conditions for the influence of the CEO’s career horizon on international pace and rhythm, and it expands the literature on how CEOs and boards of directors can influence corporate strategic decisions during the internationalization process.
