| 摘要: |
| 根据中国2000—2007年的可比价能源投入产出表，分析6部门的完全能耗系数变化趋势，并采用因素分解法，将能耗强度变动分解为直接能耗变化、产品技术变化和最终需求结构变化因素，分析不同因素对能源消耗强度变化的不同影响以及不同因素在各个部门的变化特点。结果表明：工业对煤、石油的完全能耗系数整体呈下降趋势；煤和石油的能耗强度总量呈负向变化，主要原因是其直接能耗强度变动；天然气和电力的能耗强度总量呈正向变化，主要原因分别是最终需求结构变动和产品技术变化；产品技术变化不利于农业、工业、建筑业、交运仓邮和其他非物质部门的能耗强度的下降。总体上看，国家的宏观调控和节能降耗措施产生了积极作用，但能源消耗强度存在反弹的趋势，因此仍需积极努力地实施节能减排措施。 |

| Abstract: |
| According to comparable price energy input-output table of China during 2000 2007, this paper analyzes the changing trends of the six departments of completely energy consumption coefficient, then uses factor decomposition method to decompose energy intensity into three determinants such as direct energy intensity change, product technical change and the final demand structure change, and analyzes the influence of different factors on the energy consumption intensity change and changing characteristics of different factors in various sectors. The results show that the completely consumption coefficient of industry on coal and petroleum totally demonstrates declining trend, that the total energy consumption intensity quantity of coal and petroleum shows negative change mainly because of direct energy consumption intensity change, that energy consumption intensity quantity of gas and power demonstrates positive change mainly because of final demand structure change and product technical change respectively, and that product technical change is not helpful to energy consumption intensity decline of agriculture, industry, architecture industry, transportation, storage industry, postal industry and other non-material sectors. By and large, national macro-adjustment policy and energy conservation measures have played active role, however, energy consumption intensity shows rebound trend, and thus, China should still need to implement energy conservation and emission reduction measures. |
