A: In recent years, there has been an increasing interest in …

B: Recently, researchers have shown an increased interest in…
Has it got something to do with these tenses: present perfect continuous (subject + have/has + been + verb-ing) and present perfect (subject + have/has + past participle)?

Or is it present perfect, because: there (subject) has + been (past participle), and increasing (is an adjective modifying the noun interest)?
Is B using increased as a past tense?
