作为缓解气候变化影响的重要手段，本文研究了提高发电技术效率的创新动力。相关专利被确定并用作创新的指标。我们发现，效率改进技术的专利申请随着时间的推移基本上是稳定的，最近有下降的趋势。我们还发现，大多数专利首先在经合组织国家申请，然后才在非经合组织或金砖四国申请。相反，非经合组织和金砖四国申请的专利大多在国内销售。这一结果表明，在提高电力生产效率的技术领域存在着显著的技术转移。从长远来看，这种专有技术的流动可能有助于减少新兴经济体的温室气体排放。
This paper studies innovation dynamics in efficiency improving electricity generation technologies as an important means of mitigating climate change impacts. Relevant patents are identified and used as an indicator of innovation. We find that patenting in efficiency improving technologies has mostly been stable over time, with a recent decreasing trend. We also find that majority of patents are first filed in OECD countries and only then in non-OECD or BRIC countries. Conversely, non-OECD and BRIC countries apply for patents that are mostly marketed domestically. This result shows that there is significant technology transfer in the field of efficiency improving technologies for electricity production. This flow of know-how is likely to contribute to mitigation of greenhouse gases emissions in emerging economies in the long run.
