| Energy is the driving force and basic resource of a country’s economic and social development.At the same time,it also involves three levels:environmental protection,people’s livelihood and national security.It is an important strategic material related to the national economic lifeline and national security.Therefore,the importance of in-depth research on the relationship between energy consumption structure,industrial structure and economic growth can not be ignored.This paper combines theory with practice and makes an empirical analysis of the relevant data.In the first part of the empirical analysis,various energy consumption data of various industries in China Statistical Yearbook are extracted,sorted and classified,and the data of energy consumption and total consumption in different industries in China from 2000 to 2019 are studied.We take seven major industry categories and standardize the data.Using SAS software to carry out cluster analysis on the energy consumption of various industries,and then using the idea of dimension reduction to analyze the energy structure by using the principal component analysis method,the main components of the energy consumption structure can be obtained.Principal component analysis and factor analysis model are used to study the energy structure,and several multivariate statistical analysis methods are integrated to obtain the relationship between various industries and energy consumption structure.In the second part,the consumption data and real GDP data of four kinds of energy in China from 1985 to 2019 are selected to study the relationship between energy consumption structure and real GDP from the perspective of increment.Through elasticity analysis,we can judge the interaction effect between energy consumption growth rate and economic growth rate in the past 35 years.After the stationary test and co integration test of the relevant data,the VAR model is established for impulse response analysis and variance decomposition.According to the results,the degree and mode of interaction between the growth rate of energy consumption and the actual GDP growth rate are analyzed,and the effects of coal,oil,natural gas and new energy on economic development are judged.On this basis,put forward more reasonable and perfect policies to promote the coordinated development of economy and energy,and optimize and upgrade the industrial structure and energy structure. |
