摘要:使用聚类分析法和主成分分析法,将河南省18个市依照9个指标分为3个农业经济发展类别,即农业经济发展领先区、农业經济发展中等区和农业经济发展相对落后区;分析各类别的主要指标数据,发现各地区之间存在较大的差异。选取了影响农业经济发展水平的3个主成分,并计算各指标的权重,得出农业经济发展的综合得分模型,最后针对性地提出各类地区农业经济发展的决策与建议,为推动河南省农业经济发展提供借鉴。

Abstract: Using cluster analysis and principal component analysis, 18 cities in Henan province were divided into 3 agricultural economic development categories according to 9 indicators, namely, leading agricultural economic development area, middle agricultural economic development area and relatively backward agricultural economic development area. The main indicator data of each category is analyzed, and the results show that there are large differences among regions. Three principal components that affect the level of agricultural economic development are selected, and the weights of various indicators are calculated to obtain the comprehensive scoring model for agricultural economic development. Finally, decisions and suggestions for various areas of agricultural economic development are targeted to promote Henan provide reference for the development of agricultural economy.

2019年3月8日,习近平总书记在参加十三届全国人大二次会议河南代表团审议时指出,河南省是中国的农业大省,要把实施乡村振兴战略、做好“三农”工作放在经济社会发展全局中统筹谋划和推进。河南省位于中国中部,下辖有17个地级市和1个省直管市;地属北亚热带向暖温带过渡的大陆性季风气候,全省的气温、 降水、 日照等条件适宜多种农作物的生长。2018年,河南省的粮食产量高达6 649万t,是中国粮食总产量的1/10。然而,河南省农业经济发展仍存在着区域发展不均衡、农业经济差异大等问题。据统计,2017年焦作市单位面积粮食产量为7 330 kg/hm2,而洛阳市的单位面积粮食产量仅为4 450 kg/hm2;漯河市和周口市实际耕地灌溉面积占总耕地面积的100%,而平顶山市只有52%。区域农业经济发展差异较大[1]、发展不均衡等问题始终制约着河南省的农业经济发展。……
