非谓语剖析

As well as being time consuming, it is not very effective and subject to bias.

黑体部分的being + np 如何理解

As well as being time consuming, it is not very effective and subject to bias.
1. consuming：分词形容词，意为“消耗某物的”，一般不单独用。具体用时，需在前面加上被消耗的名词，构成动宾关系的“合成词”。如： time consuming 或  time-consuming（耗时的）；energy consuming。

2. be +  time consuming：系表结构。
3. as well as 用作介词，后接动名词being。
需要解说的就这类。
