Copy the most successful country in the world? Who would want a great firewall?
Sorry to sound like a nationalist here (i'm not), but the US has 1/3rd the population of China yet still has the largest economy, and the goto reserve currency. China actually has an ownership stake in all of their IT companies. Contrary to a sibling comment, NN paves the way for the government to regulate what a private company can do with their IT assets, and therefore a great firewall situation.
USA is first by Nominal GDP, but second by PPP GDP (or third if you count the EU). I wouldn't declare a definitive winner based on that. And it's better to leave population out of that, because per capita the US is far behind countries like Norway or Switzerland, and at only half the GDP of Luxembourg (both nominal and PPP).
