Why I use "Make Pixel-Perfect" and the gameobject's transform's P:x=0.5,y=-0.5?

Why they change position?

If your sprite doesn't have even dimensions  (such as 20x30), and instead has even dimensions such as (21x33), dividing that by 2 in order to center it results in a floating point value. such as 10.5 x 16.5. That's why you see "0.5" there. It just ensures that the pixels look crisp.
