China's July 2012 exports were up barely by 1%, over the same month prior year. Exports to the European Union declined by 16.2%. A big problem is cost increases for land, labor and electricity. By 2004 China's exports were growing at a peak rate of 35%. Since then prices of inputs have increased- wages by 150%, land by 70%, and electricity prices by 30%, according to Dragonomics. The yuan appreciated by 30%. Productivity is increasing by about 8% a year, according to the World Bank. As a result of the price increases of inputs the competitiveness of China, with products exported mainly on the basis of price, is deteriorating.
