This is the only interesting way to answer the question, in my mind. I'm a little rusty on my knowledge of the situation in China, so I'll just outline my strategy.

The problem is that more liberalization will often come at the expense of other powerful CCP members. The solution is to either bribe them outright to go along, or find some other way to make sure they benefit financially: that could be something like non-controlling shares in competitors to the "company" they used to operate as a monopoly.

Another approach would be going back to the Special Economic Zones experiments. Choose the most politically expedient area first and radically liberalize it. There would probably have to be some sort of first mover advantage granted to party insiders. Then move on to the next most politically expedient area and convert that to a SEZ.

tl;dr Radical liberalization + insider trading
