Once a concept of the radical environmentalist movement, the term sustainability was incorporated into the hegemonic discourse. Prior research argues that this occurred through a process in which the original controversy between ecological and economic issues has evolved from an antagonist opposition to a broad concurrence. While this development has mainly been analysed qualitatively, we apply quantitative analysis of mass media in Austria between 1990 and 2020 to trace the changing use of the term. Applying methods of corpus linguistics, topic modelling, and dictionary based analysis, we find that the discourse has become less polarized over time, deploying increasingly positive language, and catering more and more towards the conservative parts of the population. Political actors’ presence declines significantly after 2000, and simultaneously, commercial and individual solutions are more widely discussed – everyone is responsible, and no one is to blame.

从争议到共识

可持续发展一词曾经是激进环保运动的一个概念，后来被纳入霸权话语中。此前的研究认为，这是一个生态问题与经济问题之间最初的争论从对立的反对演变为广泛同意的过程。虽然这一发展主要是定性分析的，但我们对 1990 年至 2020 年间奥地利大众媒体进行了定量分析，以追踪该术语的使用变化。应用语料库语言学、主题建模和基于词典的分析方法，我们发现随着时间的推移，话语的两极分化越来越少，使用越来越积极的语言，并且越来越迎合人口中的保守部分。2000年之后，政治参与者的存在显着下降，同时，商业和个人解决方案得到更广泛的讨论——每个人都有责任，没有人应该受到责备。
