摘要
运用非线性平滑转换模型(STR)研究了我国1953-2011年的城市化与能源消费之间的动态非线性关系。研究结果发现,城市化的变动对于能源消费变动的影响是非线性的,其关系适合使用LSTR2模型来拟合,当城市化下降较快(下降速度高于2.388%)或者上升较快(上升速度高于15.3684%)时,城市化对于能源消费的非线性影响就会显现,此时城市化变动1%会引起当期能源消费变动10.5912%。
Based on annual data over the period from 1953 to 2011 , this essay applies STR model to analyze the rela- tion between Chinese urbanization and energy consumption. The empirical results show that the relation between urbanization and energy consumption can be expressed through the nonlinear LSTR2 model. When the speed of urbanization dropped quickly (decreasing rate higher than 2. 388% ) or rose quickly ( rising rate higher than 15. 3684% ) , the nonlinear influence of urbani- zation on energy consumption will show. At this time the 1% change of urbanization will cause the change of 10. 5912% of energy consumption.
