A Tale of Two Kirzners: Time, Uncertainty, and the “Nature” of Opportunities
梳理了柯兹纳对创业研究的影响，指出其思想包含两种路径：Mark I强调警觉与机会发现，Mark II则关注时间、不确定性与创造性行动，后者可为未来研究提供新基础。
This paper discusses the influence of Israel Kirzner on the field of entrepreneurship research. We review Kirzner's work and argue that it contains two distinct approaches to entrepreneurship, termed Kirzner Mark I and Kirzner Mark II. Mark I with its focus on alertness and opportunity discovery has exerted a strong influence on entrepreneurship research in the last decade, and helped catapult the field forward. We propose that Mark II, with its emphasis on time, uncertainty, and creative action in pursuit of imagined opportunities, complements the discovery view and can provide an alternative conceptual grounding for the decade to come.
