A Statistical Study On The Relationship Between China's Energy Supply And Demand And Economic Growth

China's current situation of energy is very serious.With per capita proven reserves of energy far below the world level,energy security problems are increasing.While the energy efficiency to be further improved,the unit energy consumption is high with the irrational energy consumption structure and serious environmental pollution.To make energy and economic development,the study of relationship between energy consumption,energy efficiency and economic growth becomes more practical significance.This paper analyzes the dynamic relationship between energy consumption,energy efficiency and economic growth from the theoretical and empirical aspects on the basis of energy consumption and energy efficiency,and analyzes the relationship between energy consumption,energy efficiency and economic growth in China from 1978 to 2014.Growth data for empirical research,and finally based on empirical results put forward meaningful policy recommendations.In the paper,the background,significance,research methods and related literature review of energy consumption,energy efficiency and economic growth are introduced,and the main literature review is summarized and summarized.Second,the energy consumption,energy efficiency and economic growth of the theoretical mechanism.Based on the existing theories and current research results,this paper focuses on the interaction between energy consumption and economic growth,energy efficiency and economic growth.Thirdly,the paper analyzes the consumption of four energy sources(coal,oil,natural gas and water-wind nuclear power)in China's economic growth and energy consumption,and makes a systematic analysis of the relationship between energy consumption,energy efficiency and economic growth.Situation Analysis.Finally,the paper establishes the simultaneous equations model,which includes energy consumption,energy efficiency and economic growth.Using software 7.0,this paper analyzes the energy and economic growth in China from 1978 to 2014 and concludes that energy consumption,Energy efficiency and economic growth have two-way causal relationship between the empirical conclusion of this paper to verify the energy and economic relations in the mechanism of the three assumptions.In the last part of the article,according to the empirical analysis added,summed up China's energy supply,energy consumption is irrational,energy efficiency is low,by the extensive economic development mode,irrational industrial structure and energy development and utilization of limited technical level and other factors.And according to the empirical conclusions,some policy suggestions are put forward,such as accelerating the economic development mode,optimizing the industrial structure,increasing the proportion of the tertiary industry structure,accelerating the technological progress and developing new energy sources.Sustainable development has important practical significance.
