Cooperative R&D or non-cooperative R&D on standard-oriented technology

Our paper has analyzed and compared cooperative RD and non-cooperative RD on standard-oriented technology.According to whether a firm coordinates RD investment and information sharing,we have classified modes of innovation on standard-oriented technology into four types,which are complete RD competition,patent pool,pure RD cooperation and RD cooperation with patent pool.Based on the two classical models,we have developed a new model to discuss the performace of the above four modes.Some new findings are: On the one hand,the mechanism of overcoming the externality of information sharing on the RD investment is partly different from that of the externality of RD investment;On the other hand,none of the four modes is superior to the other three.echnology spillover is only one of the key middle factors that determinate which mode is the best and it is dependent on the character of the industry.
