Comparative Study On Productivity Of Different Agricultural Management Entities In Guanzhong Area

Guanzhong area is located between qinling and weibei mountains in shaanxi province,covering an area of 36,000 square kilometers.Including xi ’an,baoji,xianyang,weinan,tongchuan and yangling demonstration zone,xi ’an,baoji,xianyang,weinan in tons of fertile land industry area "" the guanzhong irrigation district,tongchuan,xianyang,baoji in the dry land of high-yielding maize industry area of weihe river,so the guanzhong region agricultural geographical location has a unique advantage.New type of agricultural management main body is an effective organization form of agricultural modernization development,compared with the traditional operators to the ordinary farmers,new type of agricultural management main body has many advantages,due to different economic level between agricultural management main body there is a gap,resource endowment,technology level,etc,investigating its arable land production efficiency and contrast analysis,foster the subject of agricultural management of targeted,improve the economic benefit of agricultural production has a strong practical significance.Therefore,this paper different agricultural management main body in the guanzhong area as the research object,based on the theories of ecological economy,will not expect output elements into cultivated land productivity evaluation system,using Delphi method to select the input and output elements,and then use contains the expected output of ultra-efficient SBM models in the guanzhong area the paper studies the different agricultural management main body of cultivated land productivityevaluation of guanzhong region different agricultural management main body cultivated land production level and the guanzhong internal regional cultivated land production level,based on the results of the efficiency measure,build a structural equation model,This paper analyzes the reasons for the difference in the productivity of cultivated land of different agricultural operators in guanzhong area.And put forward the corresponding countermeasures and Suggestions: the guanzhong area should give full play to the leading enterprises in the standard organization management level and strong capital advantage,and agricultural professional cooperatives technology advantages and ability to cope with the changes of the market;Due to the family farm and ordinary farmers technical efficiency is low,there are significant lack in management and technology,the government and relevant departments deal with family farms and farmers to provide more technical support and management training,reducing waste of arable land,inputs in the process of production;We will strengthen the targeted cultivation of the agricultural business entities,and constantly improve the productive efficiency of cultivated land for all types of agricultural operations.At the same time,we should pay more attention to the environmental management and technological innovation of cultivated land production,and strive to improve the sustainable development of agriculture by improving the expected output while reducing the non-expected output.
