摘要：
the conventional aggregate production function model such as Cobb-Douglas requires strong assumptions such as the constant elasticity and the full efficiency of the technique. Without restrictive assumptions, DEA involves the use of linear programming methods to construct a non- parametric piecewise frontier over the data to estimate the efficiency. However, the DEA model is being short of production function form. In this paper, we combine the advantages of the DEA and the varying elasticity production function to estimate the Frontier elasticity:firstly, estimates the technical efficiency using the DEA model, then estimates the Frontier elasticity of output with varying elasticity production functions. It is showed that the Frontier elasticity is different from that of the conventional one.
