Outline of Final Research Achievements

As one important step towards decarbonization society and transforming from one of major car manufacturing countries into a car manufacturing powerhouse, China has been putting highest priority to making the paradigm shift from internal combustion engine vehicle to new energy vehicle (NEV). As a result, China became the world largest country in NEV production, sales and ownership, and the internationally-competitiveness has been greatly improved. In order to achieve this strategic transition efficiently, the government launched a sales target regulation and credit trading system for NEVs while announcing that the purchase subsidies will be terminated in 2023. This study identified and discussed on the current situation and measurement trend of electric drive vehicle in China from a viewpoint of China’s model of NEV development. As a tentative conclusion, a China's model is indeed identified, and becoming the world’s automotive powerhouse is no longer a pipe dream for China.

Academic Significance and Societal Importance of the Research Achievements

①技術優位性を持たない中国が、再エネとNEVの普及と産業競争力の面で世界をリードできたのは、国家戦略として脱炭素化を位置づけたことの影響が大きい。②中国では、世界初となるNEV規制・クレジット取引、再エネ電力利用の目標規制・グリーン証書取引等を国レベルで導入し、脱炭素化を後押しした。③中国では、NEVを農村部で普及させる事業を展開し、NEVの導入拡大を促進できた。農村人口が多く、NEVの利用環境（自宅で充電）も整え易いなどを踏まえた対策である。各国の実情や固有性に合わせた対策が必要である。
