中国EVの低価格化の裏側とEUによる対抗措置のポイントまとめ

EU（欧州連合）による中国製電気自動車（EV）への関税上乗せおよび市場管理措置を背景に、中国製EVの圧倒的な低価格が生み出される構造と、それに対する国際社会の対応についての記事の要約および関連情報を以下にまとめました。

記事内容のまとめ

価格決定プロセスの不公正さ EUが問題視しているのはEVの最終価格そのものではなく、融資、土地、税制優遇、研究開発費、電池および原材料調達に至るまで、中国政府による広範な支援が市場の公平な競争条件をゆがめている点です。
OECDによる調査結果（2026年公表） 2005年から2024年にかけて中国企業が受けた政府支援はOECD加盟国企業の3倍から8倍に達し、中国企業の世界市場シェア拡大の約60%が補助金に起因すると分析されています。
企業国籍ではなく「生産地と支援」を対象化 EUの規制は企業国籍を問わず「中国で製造され政府支援を受けたEV」すべてが対象となります。そのため、中国工場で製造されたテスラやフォルクスワーゲン（VW）グループの車両も対象に含まれます。
追加関税と「価格約束（Price Undertaking）」制度の運用 EUは相殺関税に加え、企業が一定価格以上での販売や輸入数量の制限、EU域内での投資などを約束することで関税を免除する「価格約束」を導入し、車1台ごとの販売流通まで詳細に管理し始めています。
中国企業の対抗策と問題の複雑化 規制を回避するため、中国メーカー（BYDなど）は関税対象外のプラグインハイブリッド車（PHEV）の比率を高めるほか、欧州現地での生産工場設置を進めています。

Key Points from the Article

Unfairness of the Pricing Process What the EU takes issue with is not the final price of EVs itself, but the fact that extensive support from the Chinese government—ranging from financing, land, tax incentives, and R&D costs to the procurement of batteries and raw materials—distorts fair competitive conditions in the market.
OECD Survey Results (Published in 2026) The government support received by Chinese companies between 2005 and 2024 reached 3 to 8 times that of companies in OECD member countries, with analysis indicating that approximately 60 percent of Chinese companies’ global market share expansion can be attributed to subsidies.
Targeting “Production Location and Support” Rather Than Corporate Nationality EU regulations apply to all EVs manufactured in China that may be affected by government support, regardless of corporate nationality. As a result, vehicles produced in Chinese factories by Tesla or the Volkswagen (VW) Group are also covered.
Implementation of Additional Tariffs and “Price Undertaking” Framework In addition to countervailing duties, the EU has introduced “price undertakings”—a framework where companies can be exempted from additional tariffs by committing to sell above a set minimum price, limit import volumes, or invest within the EU—allowing the EU to manage sales and distribution down to individual vehicles.
Countermeasures by Chinese Companies and Growing Complexity To circumvent regulations, Chinese automakers (such as BYD) are increasing the proportion of plug-in hybrid vehicles (PHEVs), which are exempt from tariffs, and advancing plans to establish local manufacturing plants in Europe.

Relevant Background Information

Mechanism of Countervailing Duties Countervailing duties are trade remedies levied on products that receive direct or indirect subsidies from exporting governments, capped at the estimated amount of the subsidy. While recognized as a legitimate protective measure under WTO (World Trade Organization) agreements, a gap in claims remains due to insufficient information disclosure from the Chinese side during investigations into the actual extent of government support.
Impact on Japan’s Automotive Industry and Future Choices Chinese EVs, including those from BYD, are increasingly entering the Japanese market. The Japanese government has not implemented countervailing duties like the EU, limiting its actions to evaluating emission reduction capabilities—such as fast-charging infrastructure development and emergency power supply capabilities—as conditions for purchase subsidies. Balancing the consumer benefits of affordable choices with protective measures to safeguard the domestic auto industry’s employment and technology base will be a key issue moving forward.
