In this article, I review three decades of research conducted on turning points (TPs) in negotiation. The article begins with a historical overview that describes how the concept was discovered. The sections to follow highlight key ideas and findings. These include how negotiators monitor the process and adjust their moves, the relationship between crises and TPs, and the development and application of a three-part framework. These findings are the basis for developing a theory (or theories) of TPs. Building on the approach taken in my earlier Negotiation Journal special issue article, I use the perspective of levels of analysis (individual, interactive, collective) to provide a route for theory development. The levels idea is used as well to organize the research needed to fill gaps in our understanding. I conclude by suggesting two paths for theory development: separate theories at each of the three levels or an integrated theory based on an interplay among the levels.

转折点研究三十五年：获得的见解和需要填补的空白

在本文中，我回顾了三十年来关于谈判转折点 (TP) 的研究。本文以历史概述开始，描述了该概念是如何被发现的。以下各节重点介绍了关键思想和发现。其中包括谈判者如何监控进程并调整他们的行动、危机与 TP 之间的关系以及三部分框架的制定和应用。这些发现是发展 TP 理论（或多个理论）的基础。在我之前的谈判杂志特刊文章中采用的方法的基础上，我使用分析水平（个人、互动、集体）的视角来提供理论发展的途径。水平概念也用于组织填补我们理解空白所需的研究。
