Well, you could also look into removing some rules, in addition or instead of piling on new ones. Eg you could weaken intellectual property rights, to make it easier for upstart competitors to take on the established giants.
Or you could make it easier for foreign competitors to enter local markets. (As an example, the US has become more protectionist of their tech markets. And the EU has a lot of red tape that's even harder to follow, if you are from outside the area.)
