Business studies is considered a good foundation for a career in management in most industries, though as a graduate you wouldn't necessarily start at that level - in fact in these times new entrants can expect to start at the bottom in most jobs. But it could help your prospects of promotion once you start.
In particular, you find a lot of business graduates in corporate positions such as management consultant or human resources manager. You could also look at the kind of sector you want to work in and think about how your degree could help you there - for instance, if you are interested in retail, you could think about going into that area with a view to using your business knowledge in a management position. You could also look at more specialist sectors such as accountancy or banking.
