In this paper the input distance function is estimated for the Indian Sugar industry under alternative assumptions of weak and strong disposability of bad outputs. The estimated distance function is used to make the estimates of environmental efficiency, Malmquist productivity index and shadow prices of pollutants. The technical efficiency measure estimated under the assumption of weak disposability of bad outputs is utilized to test the Porter hypothesis. Marginal costs of pollution abatement functions are estimated for different pollutants of water. Pollutant specific taxes are computed using the tax-standards method.
本文在不良产出弱处置性和强处置性的不同假设下，对印度制糖业的输入距离函数进行了估计。估计出的距离函数用于估算环境效率、Malmquist生产率指数和污染物的影子价格。在不良产出弱处置性假设下估计出的技术效率测度被用于检验波特假说。针对不同的水污染物，估计了污染减排函数的边际成本。使用税收标准法计算了特定污染物税。
