causing是做状语么 那它的主语是什么呢？

In spite of increased adversting,we are attracting fewer and fewer people to our shows,causing our profits to decrease ingnificantly.

首先，we are attracting fewer and fewer people to our shows，是插入语，要提到最前面翻译，或者不参与成分分析

框架还是In spite of increased adversting，causing our profits to decrease ingnificantly.

因此，causing 的逻辑主语是 adversting，之间是主动关系，广告导致
全句的意思是，对于演出，我们无力吸引更多的人，尽管做了大量的广告，可是还是导致了利润的显著下滑。

没看懂什么意思？
