本文通过对改革开放以来20年的能源消费总量以及各组成部分与经济增长数据进行单位根检验、协整检验以及格兰杰因果关系检验,得出经济增长与能源消费总量、煤、石油、电力存在长期均衡关系,而与天然气不存在长期均衡关系。经济增长与能源消费总量具有双向因果关系,影响煤、石油、天然气的消费,与电力不存在直接的影响关系。 Through the unit root test, co-integration test and Granger causality test between the total energy consumption and the data of each component and economic growth since the reform and opening up, the paper draws the conclusion that the total economic growth and energy consumption, coal, petroleum , There is a long-term equilibrium of electricity, and there is no long-term equilibrium relationship with natural gas. Economic growth and total energy consumption have a two-way causal relationship, affecting coal, oil, natural gas consumption, and electricity does not have a direct impact relationship.
