Abstract

This study comparatively investigates the impact of supply chain competition on the R&D of power battery technology for new energy vehicles. From both horizontal and vertical perspectives, the supply chain competition relationships are classified into four types. By establishing a game-theoretic model, we comparatively analyze the mechanisms and impacts of supply chain competition on the innovation of power battery technologies. The research findings are as follows: (1) The optimal setting of the R&D target level for battery suppliers is the result of the combined effects of cost-effectiveness of technical R&D activities, demand effects, and the demand fluctuations brought about by competition. (2) The impact of different competitive relationships on the R&D decisions of battery suppliers varies. The R&D target level of incumbent enterprises is consistently positively correlated with the intensity of competition. (3) The distribution of the highest R&D target levels under the four competitive relationships is related to the intensity of competition and the market profitability of battery technologies. The results of this study can provide decision-making recommendations for companies involved in power battery technology R&D and offer new perspectives for consumers in choosing suitable new energy vehicles.
