To reflect current thinking, we must expand the original value chain model, which focused primarily on internal participants, to include suppliers and customers who reside well upstream and downstream from the focal organization.
请教各位老师:
1. which focused primarily on internal participants这里为什么用非限制性定从修饰 the original value chain model?
2. to include suppliers and customers who reside well upstream and downstream from the focal organization. 不定式做谓语动词expand的宾补吗?
