摘要
【目的】通过对东北地区家庭农场效率和环境影响进行实证研究,以期为其他地区家庭农场优化资源配置和降低环境影响提供依据。【方法】基于2019年对该地区289个家庭农场的问卷调查数据,运用数据包络模型测算了家庭农场效率,并在此基础上应用生命周期评价方法探究了家庭农场系统资源投入优化前后的环境影响变化。【结果】家庭农场技术效率、纯技术效率和规模效率数值均小于1,资源投入存在优化的可能性。优化后家庭农场土地、劳动力和化肥资源消耗减少。全球变暖、环境酸化和富营养化的环境影响潜值降低。【结论】提高家庭农场资源投入效率,减少温室气体等污染物排放,符合可持续发展目标12(负责任消费和生产)和可持续发展目标13(气候行动)的要求。
[Objective]The vigorous development of family farms has become a key focus of the national policy push.An empirical study on the efficiency and environmental impact of family farms in Northeast China can provide a basis for optimizing resource allocation and reducing environmental impact of family farms in other areas.[Method]Based on the questionnaire data of 289 family farms in Northeast China in 2019,the data envelopment model is used to measure the efficiency of family farms,the life cycle assessment method is used to further explore the environmental impact changes before and after the optimization of family farm system resources.[Result]The technical efficiency,pure technical efficiency and scale efficiency of the family farm are all less than 1,indicating the possibility of optimizing resource input.After optimization,the consumption of land,labor,and fertilizer resources in family farms will be reduced.The environmental impact potential of global warming,environmental acidification and eutrophication is reduced.[Conclusion]Improving the efficiency of resource input of family farms and reducing the green-house gases emission correspond to SDG 12(responsible consumption production)and SDG 13(climate action).
