从分析能源互联网建设对高耗能行业能源效率影响机制的视角出发，利用DEA-BBC模型和Malmquist指数测算了2014—2018年东中西三大地区高耗能行业能源效率值及其动态变化趋势，同时通过构建30个省级行政单位的省际面板数据模型，分析了能源互联网建设和其他因素对全国高耗能行业能源效率的影响，并进一步比较了三大地区这种影响的差异。结论表明，在现阶段，全国和地区间的能源互联网建设对高耗能行业的能源效率均存在负向影响，能源互联网的正向影响机制尚未显现。根据上述结论，本文在最后给出了相关的政策建议。

From the perspective of analyzing the impact mechanism of energy Internet construction on the energy efficiency of high-energy-consuming industries, the DEA-BBC model and Malmquist index are used to calculate the energy efficiency values and dynamic changes of high-energy-consuming industries in the three major regions of East, Central and West from 2014 to 2018. At the same time, by constructing an inter-provincial panel data model for 30 provincial administrative units, it analyzed the impact of the construction of the energy Internet and other factors on the energy efficiency of high-energy-consuming industries across the country, and further compared the differences in the impact of the three major regions. The conclusion shows that, at this stage, the construction of the national and regional energy Internet has a negative impact on the energy efficiency of high energy-consuming industries, and the positive impact mechanism of the energy Internet has not yet emerged. Based on the above conclusions, this article gives relevant policy recommendations at the end.
