so much A as B,

This is a comparison pattern, A and B can be many different forms, but usually they are of the same form.

从给出的信息判断，个人初步觉得这里的as 的意思为
used for referring to what is known:
相似的用法:
1.As I was saying, we expect 2002 to be a good year.
2. As everyone knows, the farming industry is in serious difficulties.

呵呵，俺需要更多的上下文来作出进一步判断。
