This paper re-evaluates the party system change in Turkey based on Sartori’s framework. It also explores the role of opposition parties in this. The paper suggests that, while a fragmented opposition may lead to the emergence of a one-party government and/or military intervention because of the high levels of polarization it induces, bilateral opposition prolongs one-party governments. The paper relies on an analysis of party programs and public opinion surveys in order to position the parties in terms of spatial distance and to understand the level of polarization.

通过反对保持权力：土耳其的政党制度变革

本文基于萨托里的框架重新评估了土耳其的政党制度变迁。它还探讨了反对党在这方面的作用。该文件表明，虽然由于其引起的高度两极分化，支离破碎的反对派可能导致一党政府和/或军事干预的出现，但双边反对派会延长一党政府。本文依靠对政党计划和舆论调查的分析，以便根据空间距离对政党进行定位并了解两极分化的程度。
