More and more cooperation innovations are made between traditional enterprises and makerspaces to transform the industrial mode, but the issue of good faith in cooperation innovation has greatly affected the positivity and effectiveness of cooperation. With the consideration of innovative network system factors, the evolutionary game model between traditional enterprises and makerspaces is built. The model is analyzed from equilibrium stability, conditions of sincere cooperation, solution sets of cooperative space and game evolution path, and the impact of distribution ratio, cooperation coefficient, motivation factor, detection probability, penalty factor and good faith cooperation number on the game evolution is further discussed. Finally, the numerical verification is made through the simulation, and some conclusions are proposed to promote the sincere cooperation and new innovation mode upgrade.
