2011年3月,中国中央政府制定了一个新的具有挑战性的目标,即在2011 - 2015年期间将其能源强度降低16%,此前中国已在2006 - 2010年期间实现了19.1%的降低。2011年8月,这一新目标被分配给省级当局。然而,中国各省能源经济发展不平衡,不同省份有不同的节能重点部门。以往的研究大多集中在省级能源效率的总体水平,或三个行业的水平(或一位数水平)。但无论是政策决策还是学术研究,都需要进一步细分板块。本文采用基尼系数、能源消费比重和能源强度三个指标,在两位数行业水平上比较各省的节能潜力。据我们所知,本文是第一个确定了31个省× 65个行业的节能关键。并以可视化地图和矩阵表的形式显示结果,以帮助确定节能的重点省份×行业。这也有助于中央和省级政府在监测节能进展时区分关键部门。
In March 2011, China’s central government set a new challenging target of reducing its energy intensity by 16% during 2011–2015, after it had achieved a reduction of 19.1% during 2006–2010. And this new target was assigned to provincial authorities in August 2011. However, China’s provincial energy-economic developments are unbalanced and different provinces have different key sectors for energy conservation. Most previous studies focused on provincial energy efficiency at the aggregate level, or the three-industry level (or one-digit level). However, whether for policy decision or academic research, it is necessary to further subdivide the sectors. In this paper, we use three indicators (Gini Coefficient, energy consumption share and energy intensity) to compare provincial energy conservation potentials at the two-digit sector level. To our knowledge, this paper is the first one to identify the keys for energy conversation across the 31 provinces×65 sectors. And the results are shown in visualized maps and matrix tables to help identify the key province×sectors for energy conservation easier. This also helps the central and provincial governments to distinguish key sectors when they monitor the energy conservation progress.
