Abstract:By analyzing the internal structure for the consumer innovativeness, it is divided into three factors, namely consumer innate innovativeness, domain specific innovativeness and vicarious innovativeness. In review of the factors influencing the internal structure of all the elements, it introduces the preference hierarchy theory to study the relationship between these three factors and the adoption behavior of new product. Based on this, this paper constructed the system dynamics model between the consumer innovativeness and the adoption behavior of new energy vehicles. And at the same time, it carries on the simulation and sensitivity analysis. According to system simulation and analysis, it is pointed out that a) At the beginning, Perception component?and stable innate preference have much more significant effect on the innate innovativeness, but the cognitive component, to a certain degree, has a delaying effect on the innate innovativeness. b) Innovative consumers have some problem accepting the new energy vehicles, but with the growing innate innovativeness, it stimulates each element in domain specific innovativeness to rise. c) The preference outside first has some impact on vicarious innovativeness, yet after a period of time, learning rule determined by cognitive component and incentive mechanism works and then vicarious innovativeness can be decided by both. d) The learning process of Innovative consumers leads to a lagging effect on the adoption of new product. Based on these conclusions, this paper puts forward some appropriate recommendation corresponding to the model analysis.
