这里的historical后面缺成分吗

That view represents a significant shift from the historical—which the grant of corporate privilege was to advancepublic purposes such as building roads, bridges, and canals.

以上源于一篇专八改错题，我觉得错误点是在于historical后面缺一个名词成分，但参考答案是把which改成where，请问各位老师，为何参考答案要如此改？

where 引导的定语从句修饰the historical. 假如用which, 没办法和前面构成修饰关系。the historical 是定冠词+形容词的一种表达方法，其实等于名词用途， 如the rich, the beautiful, the natural. 当然假如你加个词，只须语境允许也可以，如：the historical roles
