本研究利用物料平衡条件下的数据分析技术,评估中国建筑业不同类型能源消耗之间的环境和成本结果之间的内在权衡。对分解为技术效率和配置效率的环境效率和成本效率进行了估算,得出了为提高效率而重新配置能源投入可能造成的环境影响和经济成本。估算结果表明:(1)通过消除技术效率低下和调整能源消费结构,中国建筑业有能力以较低的CO2排放量和较低的能源投入成本创造当前的工业增加值水平。ii)如果该行业达到最环境有效和最成本有效的情况,则CO2排放量分别有31.9%和6.1%的减少潜力。(3)该行业CO2减排的平均影子成本很低,建议通过优化能源消费结构和提高能源利用效率来控制CO2排放,而不是依靠末端减排技术或排污权交易制度。
This study utilizes the data envelopment analysis technique with materials balance condition to evaluate the inherent trade-offs between environmental and cost outcomes among different types of energy consumptions in China’s construction industry. Environmental and cost efficiency that is decomposed into technical efficiency and allocative efficiency are estimated, and the possible environmental impact and economic cost of reallocating energy inputs for improving efficiency are obtained. The estimation results show that: i) China’s construction industry has the ability to produce its current level of industrial added value with fewer CO2emissions and fewer energy input cost through removing technical inefficiency and adjusting energy consumption structure. ii) There are 31.9% and 6.1% reduction potentials on CO2emissions if this industry attained the most environmentally efficient and the most costly efficient situation, respectively. iii) The average shadow cost of CO2emissions reduction in this industry is very low, suggesting that it should control CO2emissions through optimizing energy consumption structure and improving energy efficiency, instead of relying on end-of-pipe emission abatement technologies or emission trading systems.
