Vietnam's index of industrial production (IIP) grew by 9.4 percent year-on-year in the first four months of 2015, the General Statistics Office (GSO) has reported.

The GSO economists said that the encouraging IIP growth in these four months, double than what was recorded in the same period last year, was spurred by the significant rise in the industrial consumption index in the first quarter of the year. It rose by 13.9 percent, considerably higher than 5.5 percent during the same period last year.

This significant rise in the industrial consumption index also resulted in IIP increases in case of several industries. Among them were mobile phones that reflected an 89 percent rise, motorised vehicles 58.4 percent, television sets 41.8 percent, and paper production 20.8 percent.

Other industrial sectors that posted industrial production hikes during the same period were leather and footwear (24.7 percent), food for aquatic products (23.9 percent), rolled steel (17.3 percent), chemical paints (17.8 percent) and electricity production (11.1 percent).

Moreover, till April 1, the inventory index increased by 11.3 percent, lower than the 13.9 percent growth recorded during the same period last year.

Also, some industrial products that showed lower levels of inventory included furniture (39.5 percent), tobacco (19.9 percent), electronic equipment (14.2 percent), and chemical goods (11.8 percent).

Till April 1, the number of labourers working for industrial enterprises rose year-on-year by 5.5 percent, according to the GSO.-VNA
