随着经济的进一步发展,第三产业的发展水平日益成为衡量经济发展的重要标志。随着我国产业机构不断提升优化,第三产业在经济中的比重不断提高,第三产业对国民经济的推动作用越来越受到国家的重视。本文以河北省邢台市柏乡县为例,基于经济普查探究十二五规划对于河北省第三产业发展影响。本文主要是通过主成分分析方法首先将数据降维,使复杂的多个因素简化成四个主成分:Y1,Y2,Y3,Y4;进一步利用每一个因素对主成分的贡献率作为多元回归方程的权重量来构建多元线性回归方程,给出了一个总的数学模型,利用该模型对各个主成分进行分析得出结论。通过大量数据分析得出:河北省十二五规划政策对于第三产业的促进发展作用占总比的百分之六十左右。
With the further development of the economy, the level of development of the tertiary industry is increasingly becoming an important indicator of economic development. With the continuous improvement and optimization of the industrial institutions in our country, the tertiary industry’s proportion in the economy continues to increase. The role of the tertiary industry in promoting the national economy has drawn more and more attention from the state. This paper takes Baixiang County, Xingtai City, Hebei Province as an example to explore the impact of the 12th Five-Year Plan on the development of tertiary industry in Hebei Province based on economic census. In this paper, the principal component analysis method is used to reduce the dimension of the data and simplify the complex multiple factors into four principal components: Y1, Y2, Y3, Y4; further utilize the contribution rate of each factor to the principal components as the multiple regression equation Weight to build a multiple linear regression equation, gives a total mathematical model, the use of the model of each principal component analysis concluded. Through a large amount of data analysis, we can conclude that the 12th Five-Year Plan of Hebei Province plays an important role in promoting the development of the tertiary industry by about 60%.
