"Our company will shift from a high-volume low-margin strategy to a high-value strategy."
ご質問について、いくつか言い方が考えられますが、例えば、 Our company will shift from a high-volume low-margin strategy to a high-value strategy. 『我が社は薄利多売をやめて、高付加価値戦略に特化する。』
また少し変えて We will move away from a low-profit high-sales model to focus on high-value products. や We are transitioning from a volume-based approach to a value-based strategy. というようにも表現できます。
