What is hard to establish is weather productivity revolution is for real
中间的that是revolution的定语从句……应该是这样的

1.往整个句来看:
What is a hard to establish(主语从句) /is (系动词)/whether productivity revolution  that businessmen assume  they are presiding overis for real(表语从句一)

2.从表语从句一来看:
whether productivity revolution [ /that businessmen assume(作定语修饰前面名词revolution)/  they are presiding over(作assume的宾语从句)]/ is/ for real

句子主干:whether productivity revolution(主语) / is(系动词)/ for real(表语)，又是表语从句，标为表语从句二

3.从表语从句二中间看:
that businessmen(主语) /assume(谓语)  /they are presiding over
谓语部分省略了that

4.最后看宾语从句部分:
they (主语)/are presiding over (谓语)
句子为主谓结构
