影响单位GDP能耗的因素多种多样,其中结构因素是较为重要的影响因素。为客观比较地区能源效率,设法将较为重要的结构因素剔除,引入“虚拟单位GDP能耗”概念,对22个省级地区2010年的能源利用效率进行比较分析。产业层次下的虚拟单位GDP能耗是保持地区各产业部门能源消费量不变,将地区产业结构用全国产业结构替换,参照单位GDP能耗计算方法所得的结果即为地区虚拟单位GDP能耗。分析结果表明,结构因素仍然是影响地区能源利用效率的重要因素,三次产业结构调整仍是节能降耗的重要方向。对于虚拟单位GDP能耗较实际单位GDP能耗降低幅度较大的地区,产业结构调整显得尤为重要,但三次产业结构调整短期内难以实现,且具有较大的不确定性,此类地区短期内可行的节能降耗途径是调整二次产业内部结构,降低高耗能行业比重,并利用科技进步降低产品单耗。对于虚拟单位GDP能耗较实际单位GDP能耗升高的地区,其产业结构较为合理,需通过进一步优化三次产业结构、重点优化产业内部结构、降低产品单耗等方式实现节能降耗。
Various factors affect the unit GDP energy consumption, of which structural factors are more important factors. In order to objectively compare the regional energy efficiency and try to eliminate the more important structural factors, the concept of “energy consumption per virtual unit GDP” was introduced to compare and analyze the energy efficiency of 22 provinces in 2010. The energy consumption of the virtual unit GDP at the industrial level is the energy consumption of the virtual unit GDP in the region, which is the result of keeping the energy consumption in all industrial sectors in the region unchanged and replacing the industrial structure in the region with the national industrial structure. The calculation results refer to the unit GDP energy consumption. The analysis shows that the structural factors are still the important factors affecting the energy efficiency of the region. The adjustment of the three industrial structures is still an important direction of energy conservation and consumption reduction. The adjustment of industrial structure is particularly important in areas where the energy consumption per unit GDP is lower than the actual unit GDP. However, the adjustment of the three industrial structures is hard to come by in the short term and there is great uncertainty. Such short-term Feasible ways to save energy and reduce consumption is to adjust the internal structure of the secondary industry, reduce the proportion of high energy-consuming industries, and use of scientific and technological progress to reduce product consumption. For regions with higher energy consumption per virtual unit GDP than the actual unit GDP, the industrial structure is more reasonable and energy saving should be achieved by further optimizing three industrial structures, optimizing the internal structure of industries, and reducing unit consumption of products.
