【摘要】 基于对我国煤炭消费的基本分析,本文运用了协整理论分析了煤炭消费和经济增长的协整关系,建立了煤炭消费和经济增长的Granger因果关系检验模型,得出了煤炭消费和经济增长具有长期的协整关系,短期具有双向的Granger因果关系;研究了煤炭消费对能源效率的影响和对经济产出的贡献,煤炭比重的过大是我国能源效率低的重要原因,煤炭对经济的产出的贡献低于能源对经济的平均产出的贡献。更多还原

【Abstract】 The paper based on the basic analysis of China’s coal consumption,used the theory of cointegrate to analyze cointegration relationship between coal consumption and economic growth,established the Granger causality model of coal consumption and economic growth,and reached the conclusion that coal consumption and economic growth have long-term cointegrated relationship and short-term mutual Granger causality.Then the paper researched coal consumption—how coal consumption impacted the energy efficiency and the economic output.China consumed too large proportion coal that it led to the lower energy efficiency.The contribution of coal consumption is lower than the average energy in the economic output.更多还原
