能源技术创新在减少碳排放方面发挥着至关重要的作用。本文考察了1997-2008年中国大陆30个省份能源技术专利与CO2排放量之间的关系。考虑到国内生产总值（GDP）对CO2排放和能源技术创新的影响，将其纳入研究，避免了遗漏变量偏差的问题。此外，我们还考察了中国东部、中部和西部三个跨区域的群体。结果表明，化石燃料技术的国内专利对CO2减排没有显著影响;而无碳能源技术的国内专利对CO2减排有重要作用，在东部地区具有显著性，而在中部、西部和全国水平上均不显著。研究结果丰富了能源技术创新理论，并为能源技术政策制定提供了一定的启示。
Energy technology innovation plays a crucial role in reducing carbon emissions. This paper investigates whether there is relationship between energy technology patents and CO2emissions of 30 provinces in mainland China during 1997–2008. Gross domestic product (GDP) is included in the study due to its impact on CO2emissions and energy technology innovation, thus avoiding the problem of omitted variable bias. Furthermore, we investigate three cross-regional groups, namely eastern, central and western China. The results show that domestic patents for fossil-fueled technologies have no significant effect on CO2emissions reduction; however, domestic patents for carbon-free energy technologies appear to play an important role in reducing CO2emissions, which is significant in eastern China, but is not significant in central, western and national level of China. The results of this study enrich energy technology innovation theories and provide some implications for energy technology policy making.
