摘要
以山东省为例,运用主成分回归分析和灰色关联分析对山东省马铃薯种植收益的影响因素进行分析。结果发现,影响马铃薯种植收益最显著的因素是马铃薯售价,另外,人工成本、种子费用、租赁作业费和化肥费用对马铃薯收益的影响也较大。其中种子费、化肥费、主产品售价、间接成本正向影响马铃薯种植收益,农药费、租赁作业费、人工成本以及土地成本负向影响马铃薯收益。据此,提出降低马铃薯种植成本、提高收益的对策建议。
Taking Shandong Province as an example,principal component regression analysis and grey correlation analysis ate used to analysis the influencing factors of potato planting income in Shandong Province.The results showed that the most significant factor affecting potato planting income is potato price.In addition,labor costs,seed costs,rental operating costs and fertilizer costs have a greater impact on potato income.Among them,seed cost,fertilizer cost,main product price and indirect cost positively affect potato planting income,pesticide cost,leasing operation cost,labor cost and land cost negatively affect potato income.Accordingly,some suggestions are put forward to reduce the cost of potato planting and improve the income.
