Yes and no. For starters, download the report itself, which is linked to in the article. Next, it's true this isn't the best research on the topic, but unlikely you'll find better research too; if you do, post it and link to it from here.

Exactly. The article focuses on something marginal (number of large companies starting an 'innovation center' aka a tiny office in Silicon Valley has come down). The title is misleading because it makes you think it's talking about Silicon Valley being left behind in innovation.
