Abstract:With the development of group enterprises, each subsidiary has accumulated a large number of design resources. In order to realize the efficient utilization of design resources, it is necessary to study a reasonable design resource sharing mechanism. Based on the analysis of the impact of design resource sharing on subsidiary enterprises, this paper puts forward the incentive and punishment mechanism of design resource sharing and the core resource sharing mechanism oriented to priority tasks, establishes the evolutionary game model under the action of the two sharing mechanisms, solves the evolutionary stability strategy, and uses the system dynamics method for numerical simulation. The results show that the two proposed design resource sharing mechanisms can significantly promote the sharing of design resources. The two mechanisms promote the active sharing of design resources by reducing the risk of technology loss and improving the income of the subsidiary enterprises sharing design resources, which provides an effective mechanism to ensure the sustainable and healthy promotion of design resource sharing in group enterprises.
