1、华中科技大学博士学位论文中国能源效率的影响因素研究姓名：杨正林申请学位级别：博士专业：西方经济学指导教师：方齐云20090501 华中科技大学博士学位论文析表明，进一步深化国有企业改革，实行产业结构和能源消费结构优化升级，保持适度的行业竞争和合理的企业规模，加强国际贸易对能源效率提高的技术溢出效应，这些都在一定程度上有利于中国地区间、行业间能源效率差异的缩小，有利于中国总体能源效率水平的提高。最后，论文构建了一个理论模型说明开放经济条件下贸易自由化对能源效率的作用机制，研究表明，中国人均能源消费量和能源消耗强度随着

2、人均GDP水平不断提高而呈现出先上升后下降的倒“U”型曲线关系，符合“能源库兹涅茨曲线”假说。进一步的分析显示，规模效应、技术效应和结构效应的综合作用使得贸易自由化将会增加中国人均能源消费量，但有利于降低能源消耗强度。关键词:能源效率能源强度全要素能源效率影响因素II 华中科技大学博士学位论文AbstractEnergyproblemhasalwaysbecomemajorandimportantissueofChina’seconomicandsocialsustainabledevelopment.China’
