During the post-war years, Ukraine's industrial productivity doubled its pre-war level. In 1945 industrial output totalled only 26 percent of the 1940 level. The Soviet Union introduced the Fourth Five-Year Plan in 1946. The Fourth Five-Year Plan would prove to be a remarkable success, and can be likened to the "wonders of West German and Japanese reconstruction", but without foreign capital; the Soviet reconstruction is historically an impressive achievement. In 1950 industrial gross output had already surpassed 1940-levels. While the Soviet régime still emphasised heavy industry over light industry, the light-industry sector also grew. The increase in capital investment and the expansion of the labour force also benefited Ukraine's economic recovery. In the prewar years, 15.9 percent of the Soviet budget went to Ukraine, in 1950, during the Fourth Five-Year Plan this had increased to 19.3 percent. The workforce had increased from 1.2 million in 1945 to 2.9 million in 1955; an increase of 33.2 percent over the 1940-level. The end result of this remarkable growth was that by 1955 Ukraine was producing 2.2 times more than in 1940, and the republic had become one of the leading producers of certain commodities in Europe. Ukraine was the largest per-capita producer in Europe of pig iron and sugar, and the second-largest per-capita producer of steel and of iron ore, and was the third largest per-capita producer of coal in Europe.
