Nokia the world's 55 000 employees, engaged in technology research and development staff of more than 17,000, reaching 31% for R & D cost of new products accounted for 9% of total turnover, also in 12 countries around the world, including China, 44 R & D center. Too little investment in technology development and research for the domestic mobile phone, a large number of manufacturers do not even have their own R & D institutions, take the OEM directly, by buying the technology of other manufacturers to operate, the question is no technical barrier conditions, This vendor also how long? The mobile phone R & D is divided into three parts, of which the most important part of the development of the core modules, experts estimate that it can account for more than 80% or even 90% of the cost of handsets.
