基于自我控制的产品创新性决策

Decision on Product Innovativeness Based on Self-Control

基于诱惑与自我控制理论,纳入外部环境诱惑引致的自我控制成本,通过协调具有不同时间偏好的"发展者"与"生存者"对同一现金流不同价值的判断,建立了产品创新性决策模型。研究表明:①产品创新性决策由企业实施自我控制的成本与其相应的收益之间的权衡决定,其本质是不同时间偏好作用下的同一投资收益流的价值折中;②现金流引入的随机性与创新性决策计划性的增强,均导致企业倾向于选择更高的产品创新性,当决策者面临着凸性的自我控制成本时,其对产品创新性的选择会表现出动态不一致性;③外部控制的增强,也将诱导企业倾向于选择更高的产品创新性,并且外部控制与自我控制存在着相互替代的关系;④政府补贴行为通过降低企业自我控制成本,以增大创新回报,从而刺激其研发的投入与支出,并诱导企业选择更高的产品创新性。

This study,synthesizing the constraint theorem of financing cost regarding product innovation and incorporating self-control cost induced by external temptation,establishes an enterprise’s choice of product innovativeness model by coordinating different value estimations concerning the same cash flow by developers and survivors who have a dissimilar preference for time.The research demonstrates that①the decision-making of product innovation is determined by the trade-off between the cost of self-control and the corresponding income in a firm,which is in essence a compromise between values for an identical investment-return flow under the action of unlike time preferences;②bringing in cash flow randomicity and strengthening innovation decision plan can induce enterprises to tend to select a more novel commodity and decision makers’behaviors represent dynamic inconsistency in the case of convex self-control cost;③reinforcing external regulation serves luring companies to be inclined to a higher innovation of product,and there is a mutual substitution between external control and self-control;④by stimulating enterprises’R&D input,government subsidies can decline its selfcontrol cost and increase its rewards to induce enterprises to consider the higher innovation of products.
