The rapidly developed Ukrainian language-based education system dramatically raised the literacy of the Ukrainophone rural population. Simultaneously, the newly literate ethnic Ukrainians migrated to the cities, which became rapidly largely Ukrainianised—in both population and in education. Similarly expansive was an increase in Ukrainian language publishing and overall eruption of Ukrainian cultural life. At the same time, the usage of Ukrainian was continuously encouraged in the workplace and in government affairs as the recruitment of indigenous cadre was implemented as part of the korenisation policies. While initially, the party and government apparatus was mostly Russian-speaking, by the end of the 1920s the ethnic Ukrainians composed over one half of the membership in the Ukrainian communist party, the number strengthened by the accession of Borotbists, a formerly indigenously Ukrainian "independentist" and non-Bolshevik communist party. Despite the ongoing Soviet Union-wide antireligious campaign, the Ukrainian national Orthodox church was created called the Ukrainian Autocephalous Orthodox Church (UAOC).

The change in the Soviet economic policies towards the fast-pace industrialization was marked by the 1928 introduction of Joseph Stalin's first piatiletka (a five-year plan). Industrialization brought about a dramatic economic and social transformation in traditionally agricultural Ukraine. In the first piatiletkas the industrial output of Ukraine quadrupled as the republic underwent a record industrial development. The massive influx of the rural population to the industrial centers increased the urban population from 19% to 34%. Soviet collectivisation However, industrialization had a heavy cost for the peasantry, demographically a backbone of the Ukrainian nation. To satisfy the state's need for increased food supplies and finance industrialization, Stalin instituted a program of collectivization of agriculture, which profoundly affected Ukraine, often referred to as the "breadbasket of the USSR". In the late 1920s and early 1930s, the state combined the peasants' lands and animals into collective farms. Starting in 1929, a policy
