基于多元线性回归模型的长三角区域标准实施效益评价研究

Study on Evaluation of Standards Implementation Benefit in the Yangtze River Delta Based on Multiple Linear Regression Model

以2001~2018年长三角区域GDP总量、固定资产投入、就业人数、财政收入、财政支出、标准实施水平等统计数据作为基础样本数据,建立长三角区域标准实施效益分析多元线性回归模型。通过Eviews统计分析软件,对回归方程进行估计并检验,分析标准实施对长三角区域经济发展的边际影响。结果表明:标准实施对长三角区域经济发展具有显著的正相关关系,标准实施水平每提高1%,长三角区域GDP总量将增长0.18%。

Based on the statistical data of GDP,investment in fixed assets,quantity of employment,financial revenue,fiscal expenditure and standards implementation level of the Yangtze River Delta from 2001 to 2018 as the basic sample data,this paper establishes a multiple linear regression model for the benefit analysis of the Yangtze River Delta standards implementation.In Eviews software,we tried to estimate and test the regression equation of the model,then evaluated the marginal impact of standard implementation on the economic development of the Yangtze River Delta.The results show that:the implementation of standards has a significant positive correlation with the economic growth of the Yangtze River Delta,and the GDP will increase by 0.18%for 1%increase of standards implementation level.
