基于投入产出法的中长期电力需求模拟

投入产出法能很好地研究经济系统中各行业之间投入与产出的关系,利用投入产出法模拟中长期电力需求,可以反映电力需求与经济增长的内在联系,模拟结果具有很好的解释性。提出了模拟中长期电力需求的思路及模型并详细介绍了具体步骤;根据我国政府在党的"十七"大所提的人均GDP翻两番的目标,设置了GDP增长的高、中、低方案,综合考虑三大需求的变化情况,以2005年投入产出表为基准,模拟了2020年全国电力需求,包括全社会用电量、各行业用电量、居民生活用电量。到2020年,全国电力需求在6.7万亿～7.7万亿kW·h;如果到2020年刚好实现人均GDP翻两番的目标,则全国电力需求约为7.2万亿kW·h。

Simulation of mid-long term demand for electricity based on input-output method

Input-output method can well describe the input-output relations between sectors of economy system,simulating mid-long term demand for electricity based on input-output method can not only reflect the inter relation between electricity demand and economic growth,but also get the good explanatory results.Firstly the procedures for simulating mid-long term electricity demand were introduced.Secondly according to the goal of per capita GDP quadrupling that for 2000 up to 2020,three scenarios for GDP growth wer...
