中国能源经济发展阶段及 中长期节能潜力
能源经济 发展阶段 节能潜力
2013/6/25
从能源经济发展阶段来看，目前我国大致处在美国1960 年左右的水平，处在英、法、德、意、日等5 大工业国1970—1980 年间的水平。未来20 年我国的能源弹性系数潜力为0.6，单位GDP能耗下降速度将趋缓。降低单位GDP能耗与控制能源消费总量并不完全一致，未来10年内强度控制目标应当优先于总量控制目标；减少因建筑物短寿命导致的能源浪费比提高设备用能效率更为紧迫，当前应抓紧研究和出台有助于延长建...
人力资本和科技进步对能源效率的影响效应——基于区域面板数据
全要素能源效率 DEA-Malmquist指数 差分GMM
2013/12/10
基于2000-2010年中国28个省市的面板数据, 测算并比较中国东部、中部及西部的全要素能源生产率;基于人力资本视角, 通过差分GMM方法研究技术要素和人力资本要素对能源效率的影响效果。研究结果表明:中国全要素能源效率从东至西逐渐下降, 与经济水平呈现一致分布;另外, 技术进步、纯技术效率、规模效率与能源强度具有负相关性, 提高技术水平可有效提高能源效率;人力资本与能源效率也存在一定关系, 滞后...
多维理论视域中的能源政治与安全观
多维理论 能源政治 能源安全
2013/3/27
关于国际能源政治及其安全的各派理论观点虽视角各异，但其相互间实际上是互为交叉和影响，并日益呈现出共同特征。随着冷战后世界经济全球化进程的加速，各国在能源领域的相互依存日渐加强，既竞争又协调成为国际能源政治的主流。由此各方越来越重视能源领域的国际合作及其国际机制的建设，主张通过国际合作与协调来实现能源安全，将维护能源安全与实现经济和社会的可持续发展、与国家的对外政治和经济关系紧密联系起来。
