I am unsure whether the sentence would make grammatical sense as has or have had. Is this sentence fragment considered singular or plural? Is stressing a gerund that makes it singular? Because innovative studies is plural, so I assumed that this sentence was plural and I needed the use of have had.

    What sentence?? – Hot Licks Dec 17 '19 at 3:01

The verb agrees with the singular gerund, stressing. So, has. Innovative studies is an object (studies) of the gerund that serves as the subject here, with a modifying adjective (innovative). It's irrelevant.
