摘要
近年来,四川省进出口总额持续增长,但也存在一定问题,因此分析影响进出口总额因素具有一定的现实意义。深入分析影响四川省进出口贸易总额的四个因素,基于1996—2014年的历史数据,建立对数线性模型,采用逐步回归法对模型进行拟合,最后结合模型结论提出相关建议。
In recent years, the total amount of import and export in Sichuan shows growing trend, but there are still some problems. So it is of practical significance to study the factors affecting the total amount of import and export. This paper analyzes four main factors. Based on the data from 1996 to 2014, a logarithmic linear model is established and the model is fitted by stepwise regression. Finally, the relevant policy recommendations are put forward combined with model conclusions.
