Abeid, 22, has had to wait for his chance since arriving on a free from Lens over three years ago.
"It's interesting that Mehdi has a call-up for Algeria and has a chance of making the Africa Cup of Nations,'' said Pardew.
"That's something which is concerning me a bit, because he's done really well.
"He's got a great opportunity this time. He's definitely a gauge for other young players - not just at this club, but other Premier League clubs.
"He's shown that going on loan can help massively. He came back from that loan spell with Panathinaikos last season a much better player.
"It's a system I've always believed in. We have players out on loan at the moment and we'll continue to do that because I think it works.
