提高能源利用效率,对于建筑业的可持续发展具有重要意义。根据全要素能源效率框架,建立DEA模型,对2005-2010年中国省际建筑业能源效率进行研究,研究表明:这一时期,建筑业能源综合利用效率总体上有所提高,但是技术创新对于能源效率提高的作用还比较有限;能源效率存在显著的地区差异,东部沿海地区建筑业能源效率较高,中西部地区建筑业存在较为明显的能源低效利用。分析产业结构、能源消费结构、企业实力和技术水平对建筑业能源效率的影响。
Improving energy efficiency is of great importance to the sustainable development of the construction industry. According to the framework of total factor energy efficiency, a DEA model is established to study the energy efficiency of China’s provincial construction industry from 2005 to 2010. The research shows that during this period, the comprehensive utilization efficiency of energy in the construction industry has generally been improved. However, for technological innovation, The efficiency improvement is still relatively limited. There are significant regional differences in energy efficiency. The energy efficiency of the construction industry in the eastern coastal areas is high, and the construction industry in the central and western regions has obvious energy inefficient utilization. Analyze the impact of industrial structure, energy consumption structure, firm strength and technological level on energy efficiency in construction industry.
