摘要: |
利用1961—2008年数据对中国信息化与能源效率进行协整分析、格兰杰因果关系检验及脉冲响应函数分析,并建立广义差分模型。研究结果证实二者存在长期稳定的均衡关系,信息化对能源效率构成单向格兰杰因果关系,并对能源效率提升有长期稳定的推动作用。因此,大力推进中国信息化建设对提高中国能源效率有着不容忽视的作用。 |

Abstract: |
By using the data on information technology and energy efficiency in China for the year of 1961-2008, cointegration analysis,Granger causality test and impulse response function analysis were carried out, and the generalized differential model was developed. The results confirm that the two term stable has a long equilibrium relationship,and has a continued effect in the role of promoting energy efficiency. Therefore, vigorously promoting the information construction has a very impotent role in improving energy efficiency in China. |
Key words: infomationization energy efficiency Granger causality impulse response |
