【摘要】 本轮高考录取机制改革，主要表现为投档方式从院校平行志愿改革为专业组平行志愿或专业平行志愿。基于2019、2020年北京、天津、山东、重庆、河南五省(直辖市)高考录取面板数据，通过双向固定效应模型进行经验分析发现：专业组和专业平行志愿改革的平均效应均是提升考生与本科高校之间的录取匹配质量；专业组平行志愿投档更有利于考生与“双一流”建设高校之间的匹配，而专业平行志愿投档更有利于考生与双非高校之间的匹配；大多数情况下，专业组平行志愿改革对录取匹配质量的影响程度小于专业平行志愿改革。更多还原

【Abstract】 The new college entrance examination admission mechanism reform is mainly manifested in the archive delivering mode reform, which is from college parallel mechanism to major group parallel mechanism or major parallel mechanism. Based on the panel data of college entrance examinations in Beijing, Tianjin, Shandong, Chongqing and Henan from 2019 to 2020, the empirical analysis by the two-way fixed effects model shows that the average treatment effect of admission mechanism reform is reflected in the improvement of the matching quality of undergraduate admission; major group parallel mechanism is more conducive to the match between students and “Double First-Class” construction universities, while major parallel mechanism is more conducive to the match between students and universities outside the first class series; in most cases, the influence of major group parallel mechanism reform on the matching quality is less than that of major parallel mechanism reform.更多还原
