摘　　要：环保投入水平不仅积极影响环保绩效,同时也在一定程度上影响着环保绩效的离散程度。基于最大似然估计的异方差模型(R软件)不仅可以有效估计自变量与因变量间的线性关系,还可以有效厘清自变量与因变量方差之间的数量关系。The environmental public spending is not only a significant predictor of environmental performance, but also highly correlated with the divergence （standard deviation） of the performance. Methodologically, this study explores a new way to analyze the heteroscedasticity in regression models with R. In addition to the relationship between dependent and independent variables, this method also maps the relationship between independent variables and the variance of dependent variable, which can not be estimated by the Weighted Least Square or General Least Square Models by SPSS.
