| Abstract: |
| Agricultural land moderate scale operation plays an important role in innovating the mechanism
of agricultural operation， ensuring food security and improving the efficiency of agricultural production. Based on
the research of Chongzhou， the grain moderate scale management organization is divided into eight groups by using
SPSS system clustering method. The comprehensive evaluation system of agricultural land moderate scale operation
benefit is constructed from the three dimensions of economic benefit， social benefit and ecological benefit. Getting the
index weight by AHP， and using the method of entropy corrected of weighting coefficients， the contribution of three
dimensional benefits to grain scale comprehensive benefit， different scale groups of comprehensive benefit and the
organization’s overall operating conditions of grain appropriate scale management in Chongzhou city are estimated.
The results show that: in the weights of comprehensive indexes， the contribution of the three dimensional benefits to
the comprehensive benefits was different， followed by economic benefits（ 0.4044）， ecological benefits（ 0.3299）
and social benefits（ 0.2657）； In different groups，53.33-66.67 hm2，30.33-53.33 hm2，66.67-100.00 hm2， the three groups of scale have the highest operating efficiency. On the whole， the comprehensive benefits of grain
moderate scale operation in Chongzhou are still in the general level， the scale of operation is relatively small， and the
development of large-scale operation organizations of different forms is not balanced. On this basis， measures such as
strengthening agricultural land circulation and improving agricultural support policies are put forward to promote the
continuous growth of the appropriate scale operation of grain agricultural land. |
