Research on Tacit Knowledge Dissemination of Automobile Consumers’ Low-Carbon Purchase Intention

Abstract

At present, domestic consumers hold a wait-and-see attitude toward new energy vehicles. Although sales are increasing year-by-year, there is still a big gap compared with traditional fuel cars. In view of this problem, this paper starts to consider the problem from the subjective internal cause. Based on the classic SIR model, the conversion rate of low-carbon purchase inclination of consumers of new energy vehicles is introduced to build a tacit knowledge dissemination model of the interaction of low-carbon and conservative purchase inclination. The system ensures that low-carbon purchase inclination is a positively advocated consumption value, and provides decision-making reference for the government’s publicity and enterprises’ technological innovation measures. For the first time, differential dynamics are combined with the purchase inclination of consumers of new energy vehicles. This article collected 1098 questionnaires, and the statistical results show that the most effective way for people to accept new energy vehicles is word of mouth from relatives and friends. This illustrates the necessity of studying tacit knowledge dissemination among consumer groups of new energy vehicles. The questionnaire also indicates what aspects of the performance of new energy vehicles consumers are concerned about, providing empirical evidence for the realization of consumption behavior. The improved SIR model dynamically depicts the evolution process of consumers’ purchasing inclination of new energy vehicles based on differential dynamics. The stable equilibrium point of the system was solved, and the main factors affecting the tacit knowledge transmission of purchase inclination included initial market parameters, conversion rate, and low-carbon and conservative transmission rates, etc. The practicality and effectiveness of the model was verified by numerical simulation. It can provide the government and enterprises with theoretical support and development suggestions in promoting the consumption and development of new energy vehicles.
