礼貌在交际中扮演着十分关键的角色，与人际关系的建立和维护紧密相关。作为语用学、社会语言学等相关领域中的重要议题，礼貌研究经历了研究范式的变化。针对第二波礼貌研究缺少能将各种颇具价值的观点融合于一体的理论框架，Kádár & Haugh（2013）提出了礼貌实践观。该理论以“社会实践”“时间”与“社会空间”为核心概念，首次将礼貌界定为一种评价性社会实践，为多视角理解礼貌提供了具有一定操作性的分析框架，代表礼貌研究的最新发展成果。本文在诠释礼貌实践观的基础上，探讨该理论与其他经典礼貌理论之间的异同以及不足，并对未来礼貌研究进行展望。

As an important topic in fields such as pragmatics and sociolinguistics, politeness plays a key role in communication and is closely related to the establishment and maintenance of interpersonal relationships. In spite of the considerable achievements having been made and various views having been proposed in the second-wave research on politeness, there still lacks an integrated theoretical framework that can incorporate those valuable theories, concepts and understandings into a coherent whole. Seeking to address the above problem and building on the core concepts of “social practice” “time” and “social space”, the theory of Politeness as Social Practice (Kádár & Haugh, 2013) defines politeness as a form of evaluative social practice for the first time and provides an operable analytical framework for multiple understandings of politeness, thus representing a new trend of development in politeness research. Based on the interpretation of politeness as social practice, this paper compares the theory with other classic politeness theories, offers some evaluation of those theories, and outlines future developments in politeness research.
