【摘要】：为了分析影响黑龙江省畜牧业产值的因素及重要程度,根据逐步回归方法利用1995—2014年影响黑龙江省畜牧业产值的因素的数据建立了回归模型。结果表明:目前科技教育是影响黑龙江畜牧业发展的主要因素,其次是自然资源、产品产出及人力要素。同时采用通径分析方法得到隶属于科技教育的教育经费以及农业机械总动力这两个因素对黑龙江畜牧业产值的总作用分别达到0.992与0.993,说明为提高黑龙江省畜牧业的发展速度,要在提高人均畜牧业产值、合理开发利用自然环境的基础上加大科技改革、教育普及的力度,更有效地促进黑龙江省畜牧业发展。
[Abstract]:In order to analyze the factors affecting the output value of animal husbandry in Heilongjiang Province and the importance of the factors. A regression model was established based on the data of factors influencing the output value of animal husbandry in Heilongjiang Province from 1995 to 2014 by using stepwise regression method. The results showed that:. At present, science and technology education is the main factor that affects the development of Heilongjiang animal husbandry. The second is natural resources. Product output and human factors. At the same time, by path analysis method, the total effect of educational funds attached to science and technology education and the total power of agricultural machinery on the output value of animal husbandry in Heilongjiang reached 0.992, respectively. And 0.993. In order to improve the development speed of animal husbandry in Heilongjiang Province, the scientific and technological reform and the popularization of education should be strengthened on the basis of raising the output value of animal husbandry per capita, reasonably exploiting and utilizing the natural environment. More effectively promote the development of animal husbandry in Heilongjiang Province.
