Moderate Management Scale of Tobacco Agriculture Based on DEA-SBM
In order to analyze the moderate operation scale of tobacco agriculture,this paper randomly selected 105 tobacco growers in Zunyi Tobacco Industry complex as the research object,and divided the investigated samples into 8 groups according to the operation area of each grower.Considering the input of production factors and farmers'income of land management,based on the efficiency e-valuation of growers by DEA model,the super efficiency DEA-SBM model was used to analyze the efficiency differences between DEA effective decision-making units,so as to calculate the appropriate scale of tobacco production.The results showed that the com-prehensive technical efficiency of three types of planting scale 0.33-0.67 hm2,0.68-1.00 hm2 and 2.34-2.67 hm2 were all equal to 1.In super efficiency DEA-SBM,the comprehensive technical efficiency of planting scale 0.68-1.00 hm2 was the highest,followed by planting scale 2.34-2.67 hm2.The optimal planting scale for each household of tobacco leaf planting farmers can be based on the number of household labor,the number of farmers with tobacco planting intentions in a certain area,and the operating environment,ranging from 0.68-1.00 hm2 or 2.34-2.67 hm2.
