Jeffrey Rothfeder has a very good piece on that question, here is one excerpt:
Somewhat surprisingly, cross-border capital flows are equally anemic. Despite the common perception that multinationals these days manufacture their products anywhere but the West, global foreign direct investment (which reflects the amount that companies earmark for doing business in other countries) has fallen to a mere 2 percent of global GDP from 4 percent before the recession.
Still, the most tangible metric that belies the Pollyannaish depictions of globalization is corporate financial performance, which is also a window into the fundamentals of local economies. Although most companies don’t separate out geographical earnings, revenue comparisons provide an apt picture — and few multinationals can boast big returns in global markets.
There is much more to the argument, do read the whole thing.
