SHANGHAI'S booming e-commerce industry saw another year of robust growth in 2016.

The transaction volume of e-commerce hit a record high of more than 2 trillion yuan (US$290 billion) in 2016, up 21.9 percent year on year, according to data released by Shanghai Municipal Commission of Commerce.

Of that amount, e-commerce for enterprises accounted for 72 percent, reaching about 1.4 trillion yuan, an annual increase of 17.3 percent. The surge was attributed to trade growth in steel, petrol chemicals, non-ferrous metals and automobiles.
