A Parametric Approach to Estimating Eco‐Efficiency
提出用随机前沿分析替代传统数据包络分析来估算农业生产的生态效率，能控制随机噪声并分析环境压力间的替代性，并以西班牙奶牛场数据验证。
Abstract The concept of eco‐efficiency is becoming increasingly popular as a tool to capture economic and environmental aspects of agricultural production. The literature to date has exclusively used the Data Envelopment Analysis (DEA) approach to measure producers’ eco‐efficiency. We show that it can also be estimated using a Stochastic Frontier Analysis (SFA) approach. Our approach not only allows controlling for random noise in the data but also permits an analysis of the potential substitutability between environmental pressures. We provide an empirical application of our model to data on a sample of Spanish dairy farms.
