Abstract: Ambidextrous strategy plays an important role in the process of catch-up, but we still know little about how to choose the approach to ambidextrous strategy in different windows of opportunity. Through HAILUN's longitudinal case study from 1986 to 2019, it is found that latecomers usually adopt exploitative strategy when opportunities are single and relatively certain. When the opportunity is single but the uncertainty is large, latecomers usually adopt explorative strategy. When latecomers are faced with multiple and uncertain opportunity and have a high absorptive capacity, ambidextrous strategy becomes particularly important. Longitudinally, in the process from initial catch-up to beyond catch-up, the strategy of latecomers has evolved from "sequential ambidexterity" to "simultaneous ambidexterity". The conclusion of this paper not only enriches the theory of catch-up, but also complements the research on the antecedents of ambidextrous mode.

摘要： 双元是后发企业追赶过程中的重要战略，但不同机会窗口下后发企业如何实现双元我们仍知之甚少。通过海伦1986～2019年的纵向案例分析，研究发现当机会单一且比较确定时，企业通常采用利用战略；当机会单一但不确定性较大时，企业通常采用探索战略；当企业面临多重且不确定性较大的机会窗口以及具备了较高吸收能力时，共时双元变得尤为重要。长期来看，从初始追赶向超越追赶递进过程中，后发企业的双元战略由次序型模式向共时型模式演化。本文研究结论既丰富了后发追赶理论，又补充了双元模式前因的研究。
