本文对日本汽车产业中电动汽车和混合动力汽车等技术革新的经济影响进行了研究。面对全球变暖问题和石油枯竭，汽车工业已经开发了环境友好型车辆。使用汽油和柴油的传统汽车不能满足未来社会的需求。新一代汽车将在几十年内普及，产业结构将受到这些汽车的出现的影响。由于日本经济对汽车产业的依赖性很强，因此汽车产业的技术革新不仅影响汽车产业，也影响其他产业。尤其是汽车企业集中的工业地区受到新技术的影响。在本研究中，我们探讨了汽车工业的生产系统从传统的汽车技术转移到电动和混合动力汽车技术的经济影响，使用国家和多地区的投入产出模型。通过改变工业中的投入系数参数，模拟了新工艺对生产系统的转移。这项研究表明，混合动力汽车的生产具有积极的影响，但与传统汽车的生产相比，电动汽车的生产对日本经济产生了负面影响。在区域层面，我们观察到混合动力汽车的生产对中部地区的经济产生了负面影响，但对其他地区产生了积极影响。另一方面，电动汽车给东北、近畿、四国和九州地区带来了积极影响。最后，本研究结果表明，新型环保汽车的出现给日本各地区经济带来了不同的经济效益。JEL分类：R11，R15，R41
In this paper, the economic impacts of technological innovations, such as electric and hybrid vehicles, in the automobile industry in Japan are examined. The automobile industry has developed environmentally friendly vehicles in the face of global warming issues and the exhaustion of petroleum. Conventional automobiles that use gasoline and diesel oil don't meet the demands of the future society. New generation automobiles will become popular in several decades so the industrial structure will be affected by the appearance of these automobiles. Since the Japanese economy strongly depends on the automobile industry, the appearance of technological innovations in the automobile industry influence not only the automobile industry but other industries. Especially industrial regions where the automobile firms are concentrated are affected by new technology. In this study, we explored the economic impacts of shifting the production system in the automobile industry from the conventional automobile technology to electric and hybrid vehicle technology using national and multi-regional input-output models. Shifting the production system by new technology was simulated by changing parameters of the input coefficients in the industry. This study showed the production of hybrid vehicles has a positive impact, but the production of electric vehicles has a negative impact on the Japanese economy when compared with the production of conventional vehicles. At the regional level, we observed that the production of hybrid vehicles has a negative impact on the economy of the Chubu region, but has a positive impact on other regions. On the other hand, the electric vehicle brings a positive impact to Tohoku, Kinki, Shikoku and Kyusyu regions. Finally, the results of this study suggest that the appearance of new environmentally friendly vehicles brings different economic benefits to each regional economy in Japan.JEL Classifications: R11, R15, R41
