在追分赶秒的新闻业，时间是关乎职业合法性的重要命题。既有研究分析技术变革、组织常规、用户关系对时效性追求的影响，并批判新闻生产时间异化问题，但时效性的解释范围仍有待检验。基于深度访谈和文本分析，本文从人与信息、人与人、人与时间三对关系入手，探究新闻生产时间异化的原因。研究发现时效性囊括类型、视野、媒介三个维度；新闻生产时间价值在身体、社会、经济层面存在规范和经验间的矛盾。时效性和时间价值分别形成新闻生产时间的显性框架和隐性逻辑，但时效性意义过载遮蔽着新闻生产时间异化的来源，而时间价值有助于解决此问题。对比时效性与时间价值所对应的时间参照系可发现，新闻生产时间异化需从新闻从业者生命历程相关的具身视角来理解。

In the fast-paced world of journalism, time constitutes a critical issue of professional legitimacy. Existing studies have examined the influence of technological transformation, organizational routines, and user relations on the pursuit of timeliness, often critiquing the alienation of time within news production. However, the explanatory scope of timeliness remains to be further explored. Drawing on in-depth interviews and textual analysis, this study investigates the causes of the alienation of time in news production through three relational dimensions: the relationship between individuals and information, between individuals and others, and between individuals and time. The findings reveal that timeliness encompasses three dimensions: type, perspective, and medium. Furthermore, temporal value in news production is shaped by tensions between normative expectations and lived experiences across physical, social, and economic domains. While timeliness and temporal value constitute the explicit framework and implicit logic of journalistic production time respectively, the overloaded meaning of timeliness obscures the underlying sources of the alienation of journalistic production time. In contrast, the notion of temporal value provides a potential pathway for addressing this issue. A comparative analysis of the temporal reference systems underlying timeliness and temporal value suggests that understanding the alienation of time in news production requires an embodied perspective that takes into account the life courses of journalistic practitioners.
