Compared with other developed countries, China's energy efficiency level is not optimal, but it has indeed made remarkable achievements in its long-term development, mainly due to efforts targeting the adjustment of industrial structure. This research, therefore, uses a spatial econometric model to study the energy efficiency of 30 provinces in China with data from the panel from 2004 to 2019, and studies the impact of industrial structure on energy efficiency from the overall sample, for different time periods and across the three regional scales of eastern, central and western regions. The following conclusions are drawn from the empirical analysis. (1) China's energy efficiency indicators have significant geographic spatial correlation and regional spatial structure differences. (2) In the full sample condition, the industrial structure has a positive impact on the energy efficiency of China's provinces, but it also shows a significant negative spatial spillover effect. (3) Industrial structure was positively correlated with energy efficiency from 2004 to 2011. (4) The industrial structure in the east promotes energy efficiency, while the industrial structure in the central and western regions inhibits energy efficiency improvement. (5) Government intervention and scientific and technological innovation have had a spatial impact on energy efficiency in China's provinces, while marketization and the average income of residents have had no significant impact.
与其他发达国家相比，中国的能源效率水平并不理想，但在长期发展中确实取得了显著成就，主要归因于针对产业结构调整所做的努力。因此，本研究采用空间计量经济学模型，利用 2004 年至 2019 年的面板数据，对中国 30 个省份的能源效率进行了研究，并从总体样本、不同时期以及东部、中部和西部地区三个区域尺度，研究了产业结构对能源效率的影响。实证分析得出以下结论：（1）中国的能源效率指标具有显著的地理空间相关性和区域空间结构差异。（2）在全样本条件下，产业结构对中国各省的能源效率具有正向影响，但也表现出显著的负向空间溢出效应。（3）2004 年至 2011 年，产业结构与能源效率呈正相关关系。（4）东部地区的产业结构促进了能源效率，而中部和西部地区的产业结构则抑制了能源效率的提高。（5）政府干预和科技创新对中国各省的能源效率具有空间影响，而市场化和居民平均收入则没有显著影响。
