Abstract: As a resource-saving innovation model serving low-income consumers, frugal innovation conforms to the innovation trend under the new normal of China's economy. The paper studies the behaviors of three subjects (enterprise, government and consumer) that affect frugal innovation decision-making. The paper uses evolutionary game theory to explore the impact of changes in the behavior of each subject in the entire system, and uses MATLAB to perform numerical simulation analysis, in order to provide countermeasures for frugal innovation decision-making. The results show that: government's preferential subsidies, penalties and regulatory policies are helpful to enterprises' frugal innovation decision-making, but the preferential subsidies and guiding investment should be adjusted in time according to its specific situation, otherwise it is easy to reduce the speed of frugal innovation decision; the increase in purchasing power brought by low-income consumers and the increased acceptance of frugal innovation products by consumers also promote frugal innovation decision-making of enterprises.

Key words: frugal innovation decision-making, three-person game, evolutionary game theory, simulation

摘要： 朴素式创新作为一种服务于低收入消费群体的资源节约型创新模式,符合中国经济新常态下的创新趋势。本文运用演化博弈理论对影响朴素式创新决策的三方主体(即企业、政府和消费者)行为进行研究,探究各主体行为变化对整个系统的影响,并利用MATLAB进行数值仿真分析,为企业朴素式创新决策提供对策。研究结果表明:政府优惠补贴、惩罚和监管等政策措施有助于企业选择朴素式创新策略,但其中优惠补贴和引导投入要根据其具体情况及时调整,否则容易降低朴素式创新选择速度;低收入消费群体购买力度增加和消费者对朴素式创新产品接纳程度的增加也会促使企业选择朴素式创新。
