在台灣的專業大眾文藝雜誌中,《推理》以其凡282期、23年半的出版期程有著獨特的存在,一方面作為倡導者,它努力地藉由自身的專業性撐出了一塊屬於推理小說的次場域,創造了一個時代;但另一方面,它也有意無意封存了時代的印記,顯示雜誌的出版總需要在內外部因素間互動出自身路線。本論文即企圖透過量化分析,借助數字與圖表的展現,爬梳編輯路線與雜誌定位,藉以討論大眾文藝雜誌的策略與讀者可能的反應。而從小說選刊路線、專業文章分析、其他文類分析這三個方向看來,也可以看出《推理》雜誌的專業性由於六一二大限、雜誌社內部問題與政治焦慮等因素日趨退縮,無法滿足早已被教育成功的場域讀者,因此為其它出版社與媒體所取代,見證了一個時代的結束。
Among Taiwan's popular literary magazines, Mystery Magazine is a unique presence, having published a total of 282 issues over a period of 23 and a half years. On the one hand, as an advocate, it strove through its own expertise to promote a sub-field which could be classified as mystery fiction, leading to the creation of an era. On the other hand, whether intentionally or not, it also sealed the mark of the times, demonstrating that the publication of a magazine and its trajectory is determined through a combination of internal and external factors. This study discusses the strategies of popular literary magazines and the potential reactions of readers through a quantitative analysis using charts and numerical data, the combing of editing routes and an examination of magazines' orientations. From three aspects - namely, the selection of fictional works, the analysis of professional articles, and the analysis of other articles - it is clear that Mystery Magazine's professional image had been hindered due to multiple factors, such as the 612 Expiration Day, internal problems of the magazine publisher, and political anxiety. Thus, it no longer satisfied its more-educated readers in the field and was eventually replaced by other publishers and forms of media, attesting to the end of an era.
