摘　　要：以2017年全国大学生数学建模B题为背景,研究"拍照赚钱"任务定价方案。首先分析任务未完成的原因,将四个城市分成12个类别;再根据任务经纬度、任务标价、任务完成情况,利用SPSS聚类将任务编号具体分类;其次利用SPSS进行逻辑回归,得到任务定价C与任务完成率p的定价公式,对不同类别的任务进行重新定价,使任务完成率达到近90%。In the background of the 2017＇s CUMCM（B）, this paper studies the reasons why the task of ＂ photo making money ＂ has not been completed. Firstly, Clustering is used to divide the photo task into 12 categories according to the location, pricing and completion of the task; Second, use SPSS for logistic regression to obtain the pricing laws of the pricing C and task completion rate P, and to reprice different types of tasks according to this law, so as to make the completion rate reaching nearly 90 %.
