农业机械化投资行为与效益的实证分析——以湖北省马良农场为例

Empirical Analysis on Investment Behavior of Agricultural Mechanization and Benefits——A Case Study of Maliang Farm in Hubei Province

农业机械化投资是农业机械化发展的关键。当前,以农机购置补贴为代表的国家农业机械化投资政策已成为推动农业机械化发展的重要物质基础。运用线性规划法配备机器系统是进行农业机械化投资行为与效益研究的有效方法之一,其使用的前提是机器配备的约束条件与目标函数均为线性函数,在保证农业机械化投资效率最大的情况下,计算各项作业所需的动力和农机具的台数。

Investment on agricultural mechanization is the key of the development of agricultural mechanization.Currently,the agricultural machinery purchase subsidies as the representative of national agricultural mechanization investment policies to promote the development of agricultural mechanization had become an important material foundation.Using the linear programming system to equip machinery systern was one effective way for analysis on benefits and investment behavior of agricultural mechanization.The using premise was the constraints of equipping machine and objective function were linear functions,in guarantee maximum efficiency of investment in agricultural mechanization,the power required for the operation of the units and the number of farm machinery could be calculated.
