For the high-tech enterprises with weak assets in growth stage, product crowdfunding provides them with a direct financing channel. The study focuses on award mechanism of product crowdfunding and diagnoses the decision-making effect of enterprise management. Firstly, Strategy faces profit bottleneck that purses reservation incentives by price discrimination and is only applicable to small gap financing. Secondly, diminishing marginal returns result in convergence of objective function value, so there is a profit maximization scheme and a best pre-sale scale. Finally, in the marketing process of new products, the products of the pre-sale period have the substitution effect on the products in the period of production, but the scale effect will gradually release after product promotion and lower cost will give enterprises capacity of price cut and market expansion.
