Analysis on the Industry Influencing Factors of China's GDP Based on the Graph Model
This paper selects annual data of GDP in recent 23 years from China Statistical Yearbook to analyze the relationship between GDP and nine major industries,taking GDP as explained variable and nine major industries as explanatory variable,including agriculture,industry,construction industry,wholesale and retail industry,transportation,post,hotel and catering sectors,finance,real estate,and other sectors.Based on the partial correlation coefficient,the optimal threshold of 0.637 5 is selected,and the network diagram structure is built based on it.The network graph is visualized by taking GDP and nine major industries as nodes and their interdependent relationships as edges.The network graph shows that the main factors influencing GDP are industry,construction,finance,real estate,and other sectors,and only real estate shows a negative correlation with GDP.The conclusion obtained by using the network graph model is the same as that obtained by the multivariate statistical method,which verifies the correctness of the network graph model based on the partial correlation coefficient and the optimal threshold to analyze the influencing factors of GDP.However,compared with multivariate statistical methods,the network graph model makes the correlation between nodes more clear and intuitive,which is convenient to understand and analyze the industry influencing factors of GDP.
