What is the role of multi national companies in the globalisation process?

Pardon me if I'm wrong, but it seems plainly obvious you're using this forum for someone else to do your homework. I'm guessing there are plenty of people on here who have the ability to assist a student in need, but speaking at least for myself, I need to see some investment in effort. Maybe you could share what you know already, what you're a little iffy on, etc.
