China is investing large $ into its navy, and the reason is clear - to protect its sovereignty (of Taiwan and SCS) and safety of trade routes.
Particularly to type 075, I understand it as a vessel that fully provides PLA(N) vertical landing ability.
PLA has long been planning and preparing for a landing battle on Taiwan to recover its sovereignty. But before, they only has type 072, which can only do horizontal landing. It means that PLA can only land on the west coast of Taiwan island (if you look at the geography of Taiwan, east coast are mainly cliffs). PLA's enemy knew it as well, so got well prepared for it by setting barricades near shore as well as anti-landing garrison just in the coast.
With type 071, PLA got part of the vertical landing ability. And in the future with type 075, PLA has the full ability to land at anywhere they want - west coast or east coast, horizontal or vertical, a very diverse way of attack. This is the core demand of type 075, and the reason why it's been built so quick, I understand it as, is that PLA wants to solve Taiwan issue in a near future, somewhere before 2025. PLA has 5 amphibious brigades and 6 marine brigades. All of them demand the vertical landing ability, so doing some math we will know how much 075 they will need.
To give a whole picture, PLA has long been preparing to fight a battle on Taiwan, taking account of the US will help Taiwan. Before, PLA can only start the battle on the west coast of Taiwan and may get seriously hindering by US. So they developed anti-ship ballistic missiles, aircraft carriers, destroyers, and 075s. And when all these are commissioned, PLA will have the A2/AD ability over Taiwan strait, as well as a must-win confidence of the battle.
