“保护贸易论的”可以翻译为 “of the protectionist trade theory” 或者更简洁地表达核心意思时用 “protectionist (trade-related)”(此处根据具体语境,若强调与贸易理论关联,“protectionist trade-related” 可调整表述为更符合英语习惯的 “protectionist in the context of trade theory” 等类似灵活表达,但 “of the protectionist trade theory” 是最直接对应“……的”这种所属关系的翻译 )。
例如:The views of protectionist trade theory have been widely debated.(保护贸易论的观点已被广泛讨论。 )
