Information sharing modeling method of secondary double-channel supply chain based on evolutionary game

The invention relates to an evolutionary game-based information sharing modeling method for a secondary double-channel supply chain, and the method is characterized in that the method comprises the steps: constructing an information sharing system model of the secondary double-channel supply chain composed of a manufacturer and a retailer, the supply chain comprises an online vending channel of a manufacturer and a traditional offline vending channel of a retailer, and a supply chain main body is a manufacturer serving as an upstream main body and a retailer serving as a downstream main body; according to the constructed information sharing system model of the secondary double-channel supply chain, constructing an information sharing model based on a dynamic evolutionary game theory, verifying an evolutionary game stabilization strategy of information sharing, and realizing information sharing of the secondary double-channel supply chain; the supply chain upstream main body and the supply chain downstream mai
