Abstract:In the era of knowledge economy, tacit knowledge is the main source of innovation for knowledge-based employees. To realize the externalization of tacit knowledge is to encode and document tacit knowledge, which is the premise for enterprises to declare patent rights and obtain patent rights, and also the key to improve the core competitiveness of enterprises. By constructing the game model of tacit knowledge outsourcing process, It is concluded that the incentive strength of enterprises to the recessive knowledge subject of high and low potential and the probability of the knowledge subject completing a certain innovation result are the factors that affect the patentability of enterprise technology, and then put forward. Therefore, some countermeasures are proposed, such as strengthening the motivation of the high potential tacit knowledge, increasing the emphasis on the motivation of the low potential tacit knowledge, and implementing the strategy of property rights.
