Ummm...
No.
Let's take the 1913-1973 period that ends just as Soviet economic growth effectively ceases, and for which Angus Maddison has constructed reasonable estimates of economic growth (although note that I consider his estimates of growth in the Soviet Union and its dependencies too high: not enough adjustment for the low quality of most produced consumer goods). We find that national product per capita grew at (according to Maddison):
Japan... 3.52% per year Finland... 2.76% per year USSR... 2.34% per year
Stalinist industrialization achieved great things in heavy industry. But the price in foregone agricultural, consumer goods, transportation, communications infrastructure, and service sector economic performance was very high. And the net balance sheet from an *economic* point of view was not that impressive--less impressive than the overall economic performance of a Japan, or a Finland, or a Greece, or a Spain from 1913-1973.
On the other hand, Stalinist industrialization meant that when the Nazis rolled across the border the T-34 assembly lines were ready for them...
On the third hand, a Soviet Union less interested in destroying German "social fascism" before 1933 would have had less need for the T-34 assembly lines...
