While marketization has been promoted as a mechanism for improving educational equity and effectiveness, substantial evidence suggests that it may have the opposite effect. We contribute to this debate by examining educational equity and effectiveness in two similar countries that have embraced educational marketization to different degrees. Drawing on data from the Program for International Student Assessment and a causal-comparative design, we show that Australian schooling has more choice and competition, is more socially segregated, has larger school stratification of human and material resources, and has greater inequalities of educational outcomes and overall lower effectiveness than Canadian schooling. Our findings suggest that educational marketization reduces educational equity and effectiveness by increasing school social segregation and stratification of resources.

市场化对学校隔离以及教育公平和有效性的影响：来自澳大利亚和加拿大的证据

尽管市场化被宣传为改善教育公平和有效性的机制，但大量证据表明，它可能会产生相反的效果。我们通过研究两个不同程度接受教育市场化的相似国家的教育公平和有效性来为这场辩论做出贡献。利用国际学生评估计划的数据和因果比较设计，我们发现澳大利亚的学校教育有更多的选择和竞争，社会隔离程度更高，学校人力和物力资源分层更大，教育成果的不平等更大总体效率低于加拿大学校教育。我们的研究结果表明，教育市场化通过增加学校社会隔离和资源分层来降低教育公平和有效性。
