Labour market segmentation is at the forefront of national and European policy debates. While the European Commission and the OECD claim to promote what they see as more inclusive policies, academic observers remain sceptical. The dualization literature in particular points to stable equilibria that sustain divisions between labour market insiders and outsiders. In this article, we trace recent reform trajectories in a diverse group of nine European countries marked by a high share of temporary employment: France, Germany, Italy, the Netherlands, Poland, Portugal, Slovenia, Spain and Sweden. Our case studies show that recent reforms of employment regulation involve much more dynamism than one would expect based on the experiences of the two preceding decades, or from dualization or insider–outsider theories. The reform trajectories display rather contradictory approaches, sometimes in close succession.

劳动力市场细分处于国家和欧洲政策辩论的最前沿。尽管欧洲委员会和经合组织声称要推广他们认为更具包容性的政策，但学术观察家仍然持怀疑态度。双重化文献特别指出了稳定的均衡，可以维持劳动力市场内部人和外部人之间的分歧。在本文中，我们追踪了九个欧洲国家（以法国，德国，意大利，荷兰，波兰，葡萄牙，斯洛文尼亚，西班牙和瑞典）为代表的多样化改革趋势，这些国家的临时就业率很高。我们的案例研究表明，最近的就业监管改革涉及的动力远大于根据前两个十年的经验，或者来自二元化或内部-外部理论的预期。
