ABSTRACT Despite Public-Private Partnerships’ (PPPs) growing popularity within education policy circles, research on their effects yields contradictory results. The understanding of PPP effects is limited by the prevalence of generalist analyses that neglect to acknowledge the exceptional heterogeneity of the policy frameworks in which PPPs crystallize. Building on a scoping literature review, this paper aims at identifying patterns of effects of main PPP modalities on education (namely vouchers, charter schools and public subsidies for private schools) by considering the mediating role of policy-design variables. Our results show that PPP configurations oriented at the generation of market-like dynamics are frequently found to exacerbate school segregation and educational inequalities. Conversely, those PPP arrangements less conducive to market competition and those that follow an affirmative action rationale (such as targeted vouchers) are more likely to yield more positive effects on learning outcomes than other types of PPPs, without necessarily undermining equity.

政策设计如何以及为何如此重要：了解教育中公私伙伴关系的不同影响

摘要 尽管公私合作伙伴关系 (PPPs) 在教育政策圈内越来越受欢迎，但对其影响的研究产生了相互矛盾的结果。对 PPP 影响的理解受到普遍的通才分析的限制，这些分析忽视了 PPP 形成的政策框架的特殊异质性。在对范围界定的文献回顾的基础上，本文旨在通过考虑政策设计变量的中介作用来确定主要 PPP 模式（即代金券、特许学校和对私立学校的公共补贴）对教育的影响模式。我们的结果表明，以产生类似市场的动态为导向的 PPP 配置经常被发现会加剧学校隔离和教育不平等。反过来，
