摘要：

In this paper, we investigate monopolist optimal investment levels using a dynamic model under knowledge accumulation. We show that (i) investment decisions in product and process innovation are independent of each other; (ii) under both the monopolist and the social optimum, there exist the saddle stable steady state equilibria; (iii) Optimal investment levels in product and process innovation positive response to learning rate and knowledge accumulation rate, inversely response to knowledge depreciation rate.
