陕西三大区域农业机械化水平差异评价——基于主成分的分析

Evaluation of Agricultural Mechanization Level Differences in Three Major Regions in Shaanxi Province Based on Principal Analysis

对陕西省三大区域10个地市,由11个指标组成的农业机械化水平,采用多元统计中的主成分分析法进行差异评价。结果是关中农业机械化水平最高,陕北次之,陕南农业机械化水平滞后。造成这种结果的主要原因是各个地区之间在地理位置、生态条件、社会经济发展等方面的差异。因此,因地制宜选择关中、陕南、陕北农村经济和农业机械化发展模式和路径,是推动陕西农业发展的重要措施。

This research is about difference evaluations which use the principal component analysis, one method of multivariate statistical analysis, based on 11 indexes of the agricultural mechanization level from 10 cities of 3 regions in Shaanxi Province. After that, a conclusion is drawn that agricultural mechanization level of GuanZhong is the highest ; the Northern Shaanxi is lower than GuanZhong; the Southern Shaanxi is the lowest. The main reason for agricultural mechanization level differences is geographical location, ecological conditions and social economic development. Therefore, according to local conditions, choosing the proper development mode and path of the rural economic and agricultural mechanization in Guanzhong, Southern Shaanxi and Northern Shaanxi is an important way for Shaanxi to promote the agricultural development.
