| 摘 要： | CES生产函数的传统估计方法存在某些缺陷：样本数据未必满足有效性条件，利用回归分析确定参数需要进行数据变换，影响拟合优度。由于凹性CES生产函数的下图为凸集，可采用凸性DEA生产可能集对其进行拟合。

| Abstract: | There are some flaws in the necessarily satisfy effective conditions; analysis, which affects fitting goodness. convex DEA production possibility set is traditional estimation method of CES production function： the sample data would not thus the data need to be transformed to determine the parameter in regression Because the area under the concave CES production function is a convex set, the applicable to fitting it. |
