摘要
运用全国农产品成本收益资料,采用数据包络分析方法,测算了2004年至2013年的烤烟种植效率、全国20个主要省市的烤烟种植效率、非DEA有效决策单元的效率差距。结果表明:多数年份处于规模收益不变或规模收益递增状态;全国烤烟种植效率存在地区差异,13省区有着不同程度的投入冗余和产出不足现象;不同产出指标选择对综合效率测算结果造成较大影响,反映了不同省市国家利益和烟农利益之间取向的相对偏向。在此基础上,采用多元回归模型探讨了种植综合效率的影响因素,发现产值对综合效率具有显著正向影响;物质和服务费用、人工成本、土地成本3个投入要素与综合效率存在显著负向影响,说明在其他影响因素不变的前提下,单纯增加任一投入要素会造成综合效率的下降;现金收益对综合效率存在不显著的正向影响。最后根据研究结论提出四点政策建议。
Using national agricultural products cost benefit data,the efficiency of flue-cured tobacco planting from 2004 to 2013,efficiency of flue-cured tobacco planting in China＇s 20 major provinces and cities,and efficiency gap in non DEA effective decision making units by data envelopment analysis（DEA） method on the basis of cost and benefit data of national agricultural products were calculated.Results showed that returns to scale maintained steady or kept increasing for most years.Regional differences existed in the efficiency of national flue-cured tobacco planting and there were input redundancy and output deficiency in 13 provinces and regions.Selection of different output indexes had a great impact on measuring results of comprehensive efficiency,which reflected how the interests of farmers and the state were balanced in some provinces and cities.On this basis,multiple regression model was employed to investigate factors influencing plant efficiency,and it was found that output value had significant positive effects on comprehensive efficiency while material and service costs,labor costs,land costs had significant negative impact on efficiency value,and profits in cash did not have a significant positive impact on efficiency value.Suggestions are thus put forward accordingly.
