The names do not matter. It depends on the schools and the program structure. Most accounting master program in the US do not emphasize on research ability and thus won't give you a big lift for PhD application. But if you work well, you will get good recomendation letters from the professors in the US, good GPA that Americans can rely on, better English than before. If your school has an doctoral program, you may want to sit in their class, which will benefit you more.
