Abstract Considering the impact of the factors such as consumer’ s technology preference, point transaction price and technological innovation cost on the innovation behavior of supply chain members, the influence of cost-sharing contract and revenue-sharing contract on innovation level and supply chain member’ s profit is discussed respectively. The study found that the proportion of cost-sharing and the proportion of revenue-sharing increased with the increase of the point transaction price, and the level of supplier innovation increased with the increase of the point transaction price, while the sale price of new energy vehicles (NEV) decreased with the increase of the transaction price of the points. When the cost of innovation is within a certain range, the manufacturer will choose the cost-sharing contract, and when the cost of innovation is high, although both the cost-sharing contract and the revenue-sharing contract can achieve Pareto improvement, the level of supplier innovation and the profit of supply chain members under the revenue -sharing contract are both better.
