它们是学术机构还是商业机构？

Are they academic institutions or businesses?

你往北走得越远，就越看不到商业机构了。

The farther north you go, there are no businesses.

另一个例子可能是颁发证书或组织会员资格的商业机构。

Another example might be of a business that issues certifications or organizational memberships.

例如，当时在伦敦大约有130家商业机构，在那里可以买到肖像画、风景画和艺术作品的摄影复制品。

In London, for example, there were at the time some 130 commercial establishments where portraits, landscapes and photographic reproductions of works of art could be bought.
