The consequences of this are predictably twofold: regional inequalities (reflecting unequal endowments and/or political clout); and sectoral imbalances as light industry (and hence the provinces) struggle to make ends meet. Rare quantitative data indicating as much can be found in a Soviet source (Trigubenko 1985: 127), which compares trends in provincial revenue and expenditure between 1980 and 1984. Overall, both sides of the ledger declined in the early 1980s in every province except one (Ryanggang). This did not stop central government increasing its exactions by 20 per cent over the same period. By region, while the Pyongan provinces look particularly squeezed, both Pyongyang itself and the Hamyong provinces seem to have held the line in terms of cuts.
