摘　　要：本文运用SPSS的相关性分析了城镇登记失业率有关的一些经济指标,通过相关性分析去除了那些与失业率不太相关的指标,得到了影响城镇登记失业率的8个重要指标。接着建立了城镇登记失业率的非线性多元回归数学模型,得到了拟合优度较高达到0.996的模型,并对多元回归模型给出了相关分析,得到对城镇登记就业率影响比较大的是城镇化率,其次分别是第三产业占GDP比重、城镇固定资产投资和市场化程度。The paper discusses some economic indices related to registered urban unemployment rate.By relativity analysis from SPSS,then some irrelevant indices are removed.As a result,eight important indices are found.After establishing a non-linear multivariate regression mathematical model relating to urban unemployment rate,which has an R2 equals to 0.996,we find the factor which of most importance is urbanization rate,and followings are the ratio of the third industry on GDP,urban fixed assets investment and marketization respectively.
