本文以闡述包括F市在內的小城市的邊緣性城市商業娛樂空間與文化為出發點，研究F市男性青年的性消費的嬗變，以及酒吧空間的污名轉向。通過對F市男性青年的性消費行為、酒吧中的暴力衝突問題、他們與毒品的糾葛、酒托酒吧，以及具有色情污名的酒吧進行分析，本文將勾勒出2000年以來，F市性消費場所／空間的大致演變進程、與之基本同步的性消費的變化，以及對酒吧類空間的污名認知的相應變化過程。當主要的性消費空間經由洗浴中心、夜總會和Disco舞廳，逐步向酒吧轉移／發展的時候，這些空間裏的主要的性消費類型，也從直接性消費逐步轉向了非直接性消費；相當一部分城市居民對酒吧的污名認知的著重點，也從暴力衝突和毒品轉向了色情。另外，本文也進一步認為，這類邊緣性空間對於這類城市常規生活實際上的穩定作用，是不可忽視的。

The starting point of this paper is to elaborate the marginal urban commercial entertainment space and culture in small cities including F city. It focuses on the evolution of sexual consumption of youth in F City and the transformation of bars’ stigma. Through the analysis of the youth’s sexual consumption behavior, the problem of violent conflict in bars, their entanglement with drugs, the shill bars and the bars with erotic stigma, this paper outlines the general evolution process of sexual consumption places/ spaces in F City since 2000 and the basically synchronous change process of sexual consumption, and the corresponding change process of the stigma cognition of bars. As bars, replacing bath centers, nightclubs and disco halls, have increasingly become the main sexual consumption space, the main type of sex consumption in these spaces has gradually shifted from direct sexual consumption into indirect sexual consumption. In a significant portion of urban residents’ perceptions, the stigma attached to bars has shifted from causing violence and drug abuse to causing eroticization. In addition, this paper argues that the marginal spaces as such function to stabilize the urban conventional life in those small cities.
