Abstract:

Based on the consideration of the influence of consumer reference quality, a dynamic control model of product innovation and process innovation of a monopoly firm is established, in which, the demand function depends not only on the price and quality, but also on the reference quality of consumers. The optimal control theory is used to study the innovation input decision-making of the monopoly firm in the case of profit maximization and government in the case of social welfare maximization, and the paths of innovation input and product price change with time near steady-state equilibrium are compared and analyzed by data simulation. The results show that there is a unique saddle point steady-state equilibrium in the two cases. The rate of change of the two inputs increases with the increase of the reference mass, but the steady-state input decreases accordingly. When other parameters remain unchanged, the monopoly firm will increase steady-state input to product innovation with the decrease of memory parameters. The social incentives of the monopoly firm to the two kinds of innovation are higher than the private incentives.
