Eh, where was the market in this? No private possession and all.
I am centrist and point foolishness from the right, but I have to point the same on left.
USSR was far-left for sure. Communist maybe not, but far-left for sure.
We shouldn't uncritically accept Soviet propaganda about their economic system either.
The simple fact of the matter is that the Soviet economy wasn't centrally planned, for all of their pretense about the subject. And the bureaucratic climate of the Stalinist era is precisely what led to this. The First Five Year Plan was, for the most part, not an actual economic plan. It was a set of political directives to the managers of the various state-owned enterprises: produce results or there will be consequences.
But the process of planning didn't change the market driven, state capitalist character of the Soviet economy. In fact, it made it worse. As was noted by Walter Daum in
The Life and Death of Stalinism, "A significant feature of the Stalinist economy is its subdivision into separate ministries acting in many ways like the giant corporations of the West: they compete among each other for shares of the system’s overall
resources, but cannot completely suppress internal competitive tendencies."
The Plans themselves weren't actually plans in any predictive sense, merely a descriptive account of the of the bargaining between the various subdivisions over resources, and their trade over resources. Hence, these "plans" were constantly revised, and why they were always post dated from actual publication time.
Furthermore, as I previously stated, the actual economy, outside the pretesnses of Stalinist apparatchiks, ran on magic and graft. Firms hoarded resources illegally, both for personal use as well as to hedge against failures to resupply. The political elites, in turn, set new goals to force the apparatchiks to use their grafted resources to meet targets. This game ensured only continued misallocation of resources, and the dependency on semi-official expeditors and markets to trade for the needed resources for production and capital replenishment.
But many firms simply resorted to unofficial production. So rather than rely on the unplanned chaos and the fact that everyone else was running their enterprise like a personal fiefdom, many simply opted to produce needed inputs themselves, entirely outside of the plan. Something like 80 percent of industrial firms, for example, would produce their own bolts, screws, etc., often up to and including major capital goods.
In other words, the whole thing was a top-down parody of monopoly capitalism, draped in red bunting.
