This study models the income determination of a regional economy consisting of various types of industries, and decomposes the net regional product of remote islands in Japan into the income induced by central government expenditure, net income inflow, exports, and income-independent private expenditure. The result shows that 42-45% of the net regional product depends on central government expenditure. This study also proposed a non-survey approach to estimate the competitive import type of sub-prefectural regional input-output table from the corresponding prefectural table. This method assumes that: (A) Among the sub-prefectural regions, the share of regional output of sector i’s product exported to outside the prefecture is consistent, and the share of imports from outside the prefecture in the regional demand for sector i’s product is also consistent; (B) The share of cross-hauling in the trade volume of sector i’s product is equivalent in interregional trade and trade between the prefecture and outside the prefecture.
