摘要
在以往农业机械化评价方法的基础上,提出了用因子分析方法评价农业机械化发展水平。选取反映农业机械化作业水平、保障水平、效益水平的评价指标进行因子分析赋予权重,结合各项指标系数值,建立农业机械化发展水平评价方程。同时,计算出我国31个省、自治区、直辖市的农业机械化综合发展水平评价值。结果表明:采用因子分析法评价是以数据本身的相关性为依据,避免了其它方法人为赋权所产生的误差。
The paper use a great deal of material and number which about our country＇s agriculture mechanization and put forward a new method-factor analysis to evaluate the level of agriculture mechanization. The writer selects certain item which can reflect agriculture mechanization into evaluation system and be given power by factor analysis. The system contains work level term, benefit level term, and assure level term. Then the evaluation model is constructed. As result the values of agriculture mechanization development level in 31 province and autonomous regions are counted.
