摘要:
【目的】将环境成本纳入分析范畴,对规模化养猪场进行效益分析,为全面揭示与评价养猪场的费用效益提供参考。【方法】根据环境价值理论和规模化养猪场的环境问题,构建规模化养猪场环境成本的计算方法;用构建的环境成本计算方法,计算陕西咸阳市某规模化养猪场2006年的环境成本,并对其进行了费用效益分析。【结果】该养猪场当年环境成本高达13万元多,其利润的50.2%以上是以环境损失为代价的,效费比低于1.07,利润较差的年份其效费比则更低。【结论】构建了基于环境成本的规模化养猪场费用效益分析方法,该方法能够全面揭示和评价养猪场的费用效益,有助于引导养猪场改善生产条件、减少资源消耗和环境损失。

A cost-benefit analysis of the large-scale pig farm based on environmental costs
Abstract:
【Objective】A new perspective analyzing the costs and benefits of large-scale pig farms by cost benefit analysis based on environmental costs for a comprehensive understanding was provided.【Method】According to the environmental value theory and environmental problem of large-scale pig farms,method of calculating environmental cost was established,and the environmental cost of a large-scale pig farm in Xianyang City of Shaanxi Province in 2006 was calculated,and cost and benefit were analyzed based on it.【Result】Results showed that the environmental cost of the pig farm was more than 0.13 million yuan in 2006,more than 50.2% of its profit was at the cost of environmental losses,benefit-cost ratio was less than 1.07,which could be lower in years with lower benefit.The Government should plan and guide the pig farm production based on consideration of environmental costs.【Conclusion】A method was provided to analyse the costs and benefits of pig farms based on environmental costs,which is helpful to an overall understanding of the costs and benefits of the pig production industry,and will help government draw up policies to guide the sustainable development of the pig production industry.
