Central planning is very good for pulling a country out of an a poorly developed state into a highly developed state. The USSR experience this under Stalin (setting aside that he was a mass murderer) which created an industrial power. Even in the US, during WW2 the industry was centrally planned and that pulled the US out of the Great Depression.
However, central planning as proven to be bad once you reach a developed state. Lots of reasons for this which would be too long to get into here, but has a lot to do with people willing to follow a sacrifice when there is a crisis or the country is working together to get itself out of a bad situation.
