The Corporate Goods Price Index (DCGPI) measures the price movement of domestically-produced and domestically-used goods with sample prices; collected either from the producer or wholesaler of these goods. The weights of the index are based on the value of producers shipments for domestic demand, which are calculated by subtracting the value of exports (from Japan Exports; Imports published by the Ministry of Finance) from the value of total producers shipments (from Census of Manufactures published by the Management and Coordination Agency). The Wholesale Price Index changed name to Corporate Goods Price Index. The name of the index has been changed to the Corporate Goods Price Index because this name better reflects the character of the index compared with the previous name Wholesale Price Index. The index remains focused on the prices of goods traded among companies.
