日本政府将在2020年后采用CAFE标准。本研究使用“修正”的SBM模型，对2016年日本制造商销售的113款汽油车（GV）和54款混合动力车（HV）的技术效率进行了分析。我们还估计了特定车型可达到的燃油效率，这些车型可以参考最佳实践边界上的最近点进一步改进。计算了9家汽车制造商改进后的CAFE值和标准。与汽车技术前沿相比，汽油汽车的技术差距更为明显。此外，大多数汽车制造商可以通过基于最佳实践技术的有效实现策略来实现CAFE标准，而其他汽车制造商即使在GV和HV的最佳实践前沿之外进行快速技术创新也无法实现CAFE标准。
The Japanese government will adopt the CAFE standard after 2020. By using a "modified" slacks-based measure (SBM) model, this study analyzed the technical efficiency of 113 gasoline vehicle models (GVs) and 54 hybrid vehicle models (HVs) sold by Japanese manufacturers in 2016. We also estimated attainable fuel efficiency of specific vehicle models that can be further improved referring to the nearest point on the best practice frontier. The improved CAFE values and standards of the nine automobile manufacturers were calculated. The technology gap from the vehicle technology frontier was more noticeable among gasoline vehicles than among hybrids. Moreover, most automobile manufacturers can achieve the CAFE standard through an effective achievement strategy based on best practice technologies, whereas the others will not achieve the CAFE standard even given a rapid technology innovation beyond the best practice frontiers for GVs and HVs.
