Modern mathematics thought and method have been integrated into the society, economics, biology, information and many other subject fields. Mathematics is becoming more and more important. Having good mathematics accomplishment is the basic requirement of contemporary university students. By estab-lishing the PA-LV Model, we can research the problem of uni-versity students' mathematics learning efficiency. In conclusion, mathematics quality has a significant effect on mathematics knowledge, but it has little influence on the mathematics ability. And mathematics ability is greatly influenced by the knowledge of mathematics. At last, we put forward some relative advice.%现代数学的思想和方法已融入到社会、经济、生物、信息等众多学科领域,数学学科的重要性日趋呈现,具备良好的数学素养是对当代大学生的基本要求.本文通过建立潜在变量路径分析(PA-LV)的结构方程模型深入研究大学生数学学习效能问题,检验结果发现"数学品质"对"数学知识"有显著影响,"数学品质"对"数学能力"影响微弱,而"数学能力"主要受"数学知识"影响,并提出建议.
