Estimating energy interindustry linkages based on the Hypothetical Extraction Method (HEM) in China and USA

Energy efficiency policies can help to reduce energy use and mitigate the effects of climate change. This paper examines the U.S. and Chinese economies by applying HEM to both. Key sectors absorbing more energy from other sectors by purchasing intermediate products from them and, simultaneously, transferring more energy by selling products to the rest of the sectors are identified. This provides insights for decision-making on appropriate energy efficiency policies. It appears that the U.S. economy should focus on the service sector, and the Chinese should focus on the industrial sector.

能效政策可有效减少能源消耗，缓解气候变化带来的负面影响。本文将HEM应用于美国与中国经济体系，展开对比研究。文中甄别出同时兼具双重能源流转特征的关键部门：此类部门既通过从其他部门购入中间产品以吸收更多来自外部的能源，又通过向其他部门出售产品以向外传导更多能源。该研究结果可为适宜的能效政策制定提供决策参考。研究显示，美国的能效政策应聚焦服务业，而中国的能效政策则应重点关注工业部门。
