Industrial output for June was revised downward Wednesday to a seasonally adjusted gain of 2.3 percent from the previous month instead of 2.4 percent as earlier reported, the government said.
The index of production at mines and factories was also revised downward, to 80.9 against the base of 100 for 2005, from 81.0 in the preliminary report, because data that were unavailable when the report was released July 30 put downward pressure on output, the Ministry of Economy, Trade and Industry said.
Still, the downgraded figures constitute the fourth consecutive month of gains in industrial output and the longest winning streak seen in nearly two years.
Production by electronic parts and device makers led the overall increase in output, revised to 12.9 percent from 12.5 percent, on demand for such products as semiconductor integrated circuits for mobile phones and portable music players, the ministry said.
Output by transport equipment manufacturers, including carmakers, rose 1.4 percent, much faster than the initially reported 0.7 percent, helped by the robust output of cars.
The index of industrial shipments meanwhile gained 3.5 percent to 81.7, unchanged from the preliminary report, while that for industrial inventories dropped 1.1 percent.
