Against the background of increasing trading protectionism and anti-globalization, market access intervention has become a common method used by many countries to restrict the foreign enterprises. This paper studies the reconfiguration of supply chain under market access intervention, and constructs models before and after intervention. Before the intervention, suppliers provide components, which are processed by manufacturers and converted into products for sale to two markets. After the intervention, the supply chain will be reconfigured and the manufacturer’s products can only be sold in one market. But customers from the interfered market will flow into the intervened market to buy the products. The study found that compared with the benchmark model before intervention, in pricing: For suppliers, if the two markets are more substitutable, the price of components will decrease. If the two markets are less substitutable, the price of components will increase when the inflow purchase potential is great and decrease when it is weak. For manufacturers, the pricing of their products is not only related to the above two factors, but also related to the size of the market that has not been interfered. Moreover, this article finds that the changes in the pricing strategies of suppliers and manufacturers are not always in the same direction, that is, there may be situations in which suppliers increase (decrease) the component price but manufacturers decrease (increase) product prices. In profits: For suppliers, if the two markets are more substitutable, the profits will decrease after intervention; if the two markets are less substitutable, the profits will increase when the inflow purchase potential is great and decrease when it is weak. For manufacturers, in addition to the above two factors, the changes in their profits are also related to the size of the undisturbed market and the unit cost. The results show that market access intervention does not always reduce the profits. There is also the possibility of increased profit if the company adopts a reasonable pricing strategy. This study not only enriches the supply chain management theory, but also provides decision-making and solutions for supply chain pricing issues under market access intervention.
