摘要
分析了江西粮食综合生产能力的演变和影响因素,通过构建回归模型和定量分析,得出几个有价值的结论,即:(1)乡村劳动力对粮食生产增长的贡献率最大;(2)粮食作物种植面积对粮食生产的作用在诸要素中较大;(3)农业排灌机械动力和粮食收购价格指数与粮食生产呈负相关。
By establishing regression models and quantitative methods, this paper analyses the advancement of synthetic production ability of agriculture in Jiangxi Province and its influential factors. Several valuable conclusions are drawn : ( 1 ) Rural labor force has the greatest contribution to the increase of grain production. (2) The area of grain crops has a greater effect on grain production than other factors. (3) Farm irrigation and drainage mechanical power and grain purchasing price index have negative correlation to grain production.
