This paper contributes to the geography of transitions literature by conceptualizing transition trajectories from a multi-scalar perspective. It combines an institutional perspective of transitions with conceptions of scale from human geography to derive a framework which explicates how (de-)institutionalization and re-scaling mechanisms condition different transition trajectories. Our conceptual elaborations show that the traditional local-global niche cumulation and upscaling trajectory can be complemented with two alternative trajectories that build on analytically different sequences of institutionalization and re-scaling processes. This is illustrated through a case study of technology standardization in the sanitation sector, more specifically the development of the ISO 30500 standard for non-sewered sanitation systems, which was initiated by a consortium led by the Bill and Melinda Gates Foundation. The observed transition trajectory departs from key assumptions of the local-global niche model, with actors engaging in direct institutionalization at the global level, followed by re-scaling global rationalities into different (sub-)national contexts.

本文通过从多标量的角度对转变轨迹进行概念化，为转变文献的地理学做出了贡献。它将转型的制度视角与人文地理学的规模概念相结合，得出一个框架，该框架解释了（去）制度化和重新规模化机制如何调节不同的转型轨迹。我们的概念阐述表明，传统的本地-全球利基累积和升级轨迹可以补充两个替代轨迹，这些轨迹建立在制度化和重新调整过程的不同分析序列上。这通过卫生部门技术标准化的案例研究得到说明，更具体地说，ISO 30500 非下水道卫生系统标准的制定，这是由比尔和梅琳达·盖茨基金会牵头的一个财团发起的。观察到的转型轨迹偏离了地方-全球利基模型的关键假设，参与者在全球层面直接进行制度化，然后将全球理性重新调整到不同的（次）国家背景中。
