Which entertainment business is the best for after school graduation? I want to know which industry school should I focus on. I feel like I want to be a producer someday.
it depends on your interests. I wouldn’t let other things besides yours skills, interests and passion help dictate your direction. If you do, you may not be happy later.
Now, having said that, I’d stay away from 3D. I don’t think that area is growing anymore. 
But, I have heard that not much people still make 2D animation because 3D computer animation is newer than 2D drawing animation.
Good production management skills are transferable, so the advice still stands. Focus on an area that interests you and go into that. There’s still 2D animation in so many different areas. If you can work in production co-ordination on a 2D show, you’ll need the same scheduling and budgeting skills you’l need on any show. Focus on getting a job in an area that interests you and go from there
