Forbes comments: "Recent figures suggest China's labor costs are rising fast, which could be good news, and could be bad. Certainly the amount of Chinese people able to rise out of poverty is one of the signature achievements of the early 21st century, but the prospect of wage inflation could signal bad news for an economy whose key comparative advantage has until now been low labor costs. The speed of the increase, however, invites consideration of whether China has reached the 'Lewis Turning Point'?... It comes about as the migration of agricultural labor to the industrializing cities–released by agricultural mechanization–starts to slow up, and results in a rapid rise in wage costs as the available labor pool becomes suddenly shallower...Rising wages may spur a long awaited boom in domestic consumer spending and speed China along the manufacturing value curve as higher labor costs drive investment in more capital intensive production technology. In turn this might raise the prospect of resource efficiency gains, rather than the simple resource deployment gains that have hitherto driven China's growth, creating a virtuous cycle of growing demand and better calibrated investment and helping China vault over the middle-income trap."
