Auto suppliers in China, now the most profitable in world, are expected to increase revenues, profit margins and acquisitions - including overseas ones - this year, as well as increase their drive for new technologies, according to a new study by the global business-advisory firm AlixPartners LLP. The study, which included a survey of 50 senior executives from both foreign and domestic players in China’s auto-supply and original-equipment manufacturer (OEM) sectors, also included the prediction that the market share of domestic automakers in China will rise to 36% this year, up from 32% in 2009.
