摘要
利用ARDL模型对中国可再生能源消费和能源碳排放之间关系进行研究,研究结果表明可再生能源消费作为被解释变量时可再生能源消费、能源碳排放和经济增长之间存在长期协整关系;从长期来看,可再生能源消费对能源碳排放具有显著正向影响关系,且长期弹性是0.51,而短期内影响关系不显著;而且Granger因果检验发现存在可再生能源消费到能源碳排放的单向因果关系。
The ARDL model is used to explore the nexus between renewable energy consumption and energy-related CO2 emission, and the results show that when renewable energy consumption is regarded as dependent variable, there is counteraction relationship among renewable energy consumption, energy-related CO2 emission and economic growth. In the long-run renewable energy consumption influences energy-related CO2 emission positively and significantly, and the long- run elasticity is 0.51, while the result is insignificant in the short-run. The result of Granger causality shows that there is unidirectional causality from renewable energy consumption to energy-related CO2 emission.
