You seem to be misunderstanding. The location listed on articles refers to where the reporting was primarily done by the reporter(s) involved. The article isn't "published from within China". And it's misleading to say it's "material originating from China". It's material originating from the Economist, a British publication, from a reporter who traveled to (or is based in) Shenzhen to research this story. China has no say whatsoever in the content of this story. The point of putting "Shenzhen" as the location is simply that this wasn't reported by a journalist merely sitting on their couch in London. Good reporting generally requires you to actually go to the places you're reporting on.
