The government of Japan has released Regional Economy-Society Analyzing System (RESAS) on the internet since April 2015 to support the promotion of Regional Revitalization Policy. It is appreciated that Regional Economic Circulation Map (RECM), the most basic one of RESAS's analyzing tools, stresses private economic activities; it analyses regional income from the three aspects of production, distribution and expenditure discriminating between the domestic economic activities in a region and the economic activities of the region's inhabitants; it deals with income transfers in some way; it sifts the viewpoint from traditional exports based to economic circulation based; it provides not only data by all prefectures but also data by all cities and municipalities.
Regarding RECM, such problems are pointed as that; it cannot explain entire money flow in a region because it doesn't distinguish money from added value; its economic circulation based viewpoint seems to remain within the traditional exports based viewpoint; even if Regional Economic Circulation Ratio, a measure introduced in RECM, goes up, income per capita would not grow because the Ratio would not be cause but effect of economic activities.
The most questionable idea of RECM is that it overstresses earning power in the low income districts on the assumption that they have not enough money. But in actually they have decent money in terms of Balance of Payment. It should be considered that public economy might crowd out private economy and expending power might be weak in such districts.
