本文采用LM单位根检验对中国电力消费总量的时间路径进行了研究。研究发现:1978~2009年间中国电力消费总量为带有两次结构突变的趋势平稳过程,电力消费总量序列对随机冲击具有"短记忆"性质。这对相关能源政策、经济发展战略与措施的有效性论证具有一定的启示作用。
The time path of China’s electricity consumption(EC)is analyzed with LM root-test.The results indicate that EC is a trend stationary process with two structural break points and has"short memory"to random shocks.These viewpoints have the certain important enlightenment function for proving effectiveness of relative energy policy,economic development strategies and measures.
