基于主成分回归对东北三省畜牧业总产值与其影响因素的对比分析

Contrastive Analysis of the Total Output Value of Animal Husbandry and its Influencing Factors in the Three Northeastern Provinces Based on the Principal Component Regression

以1994-2017年东北三省畜牧业总产值相关数据为样本,采用主成分回归模型从自然资源、经济环境、产品产出、教育科技四个方面对影响东北三省畜牧业总产值的因素进行分析,并按照各个变量对畜牧业产值影响大小进行了对比分析.分析结果表明:目前科技教育是东北三省畜牧业总产值的主要影响因素,而经济因素对东北三省畜牧业发展起阻碍作用但是与其他变量相比相对较弱.经济市场的价格变动并不是影响畜牧业产值的关键因素.因此,要提高东北三省畜牧业总产值,应该不断加大教育经费投入力度,提高畜牧业相关从业人员的专业素养,培养一批懂经营、懂管理的畜牧生产技术人才.

To contrastive analysis of the total output value of animal husbandry and its influencing factors in the three northeastern provinces,using the principal component regression model and according to the data of natural resources,economic environment,product output,education from four aspects in 1994~2017 and according to the variable size,the influence on animal husbandry output value is analyzed.The analysis results show that:science and technology education is the main influencing factor of the total output value of animal husbandry in the three northeast provinces,and the economic factor hinders the development of animal husbandry in the three northeast provinces,but it is relatively weak compared with other variables.The price change of means of production is not the key factor that affects output value of animal husbandry.Therefore,in order to improve the total output value of animal husbandry in the three northeastern provinces,the investment in education funds should be increased,the professional quality of the relevant practitioners of animal husbandry is improved,and a group of skilled people who know how to operate and manage animal husbandry production are cultivated.
