基于逐步回归模型的金银花价格影响因素实证分析

Empirical Analysis on Influencing Factors of Honeysuckle Price Based on Stepwise Regression Model

以近年来山东平邑县道地药材金银花的产地价格数据为基础,建立逐步回归模型,确定模型的主要参数,对金银花价格的影响因素进行分析。结果表明,选取的区位因素中,农业增加值、公路里程数、常住人口数和农民专业合作社个数对金银花产地价格具有明显统计学影响,文中构建的逐步回归模型对金银花价格走势的拟合度很好,符合模型的预期要求。

Based on the price data of Lonicera japonica flos in Pingyi County,Shandong Province in recent years,this paper establishes a stepwise regression model,determines the main parameters of the model,and analyzes the influencing factors of Lonicera japonica flos price.The results show that agricultural added value,highway mileage,permanent population and number of farmers'professional cooperatives have significant statistical influence on the price of Lonicera japonica flos.The stepwise regression model constructed in this paper has a good fitting degree to the price trend of Lonicera japonica flos and meets the expected requirements of the model.
