“可供性”（affordance）已成为当前媒介研究的核心概念之一。由于概念脉络复杂 且难以把握，传播学对affordance概念的运用往往失之要义。本文梳理了该概念的来源和 背景，探索了该概念引入传播学的关键节点，指出了其中的范式变迁与概念转义，并辨 析了“可供性”这一译名的问题。本文建议将affordance译为“示能”。作为一个跨学科 概念，“示能”强调了具身性、物质性和主客体对称性三项属性，为媒介研究突破目前 困境提供了可能的进路，亦为传播学之转向与重构提供了有利的起点

Affordance, a pivotal concept in media studies, has lost its kernel during the appropriation in communication studies, which showcases the complexity of grasping its original and nuanced complications. Teasing out its origins and contexts, this paper examines the junctures of appropriation to delineate the paradigm shift and conceptual translation behind it, which draws our attention to the mistranslation “Kegongxing”. This paper proposes the term “Shineng” to replace it. As an interdisciplinary concept, “Shineng” highlights trifold properties, including embodiment, materiality, and object-subject’s symmetry, serving as a possible way-out for the predicaments of media studies as such and an advantageous pinpoint for the shift and reconstitution of communication studies as a whole.
