摘　　要：我国普通高校大学生竞赛正处于蓬勃发展期,赛事的举办和参与都呈现出积极向上的态势。大学生学科竞赛能够反映参赛院校的学科发展水平和教学水平,而基于竞赛数据对院校水平进行分析和比较也能够在一定程度上促进院校对竞赛的重视和参与度。在之前的研究和实际应用中,学校的竞赛水平评估大多局限在奖项得分的堆叠上。这种基于“唯奖项”论的模型因为忽略了院校自身发展水平等因素而存在片面性。在这项工作中,参赛院校的竞赛水平可以用参赛积极性、参赛优异度和获奖稳定性3个指标刻画并构建评估模型;通过最大化院校间得分差异确定指标的最优权重,从而获取院校的参赛得分并进行比较和分析。此外,根据学科竞赛的特点,院校在竞赛的不同赛道上的不同表现可以作为更加细化的特征。通过t-SNE降维、可视化与聚类分析,参赛高校被划分成4种类型。对于不同类型的高校,文中分别提供了提高比赛表现的针对性建议。江苏省大学生计算机设计大赛举办至今的数据被用于验证模型的合理性。The college student competition in China is booming,both the holding and participation of events show a positive trend.The discipline competition of college students can reflect the discipline development level and teaching level of participating colleges,and the analysis and comparison of the level of colleges based on the competition data can also promote the colleges'attention and participation in the competition to a certain extent.In previous research and practical application,the evaluation of the school competition level is mostly limited to stacking award scores.The model based on the“award-only”theory is one-sided because it ignores the development level of colleges and universities.Activity,performance,and stability indexes can describe and evaluate the competition level of participating colleges and universities.The optimal weight of the index is determined by scatter degree method so as to obtain the scores of colleges and universities.In addition,according to the characteristics of the discipline competition,different performances of colleges and universities on different courses of the competition can be used as more detailed characteristics.The participating colleges and universities are divided into four types through t-SNE dimension reduction,visualization,and cluster analysis.For different types of colleges and universities,specific suggestions to improve the performance of the competition are proposed in this paper.The data from Jiangsu College Student Computer Design Competition since its inception is used to verify the validity of the model.
