Abstract: Under the background of manufacturers applying blockchain technology and conducting green research and development, the game models for green supply chain considering government subsidies are constructed based on reselling mode and agency selling mode, and the influence of consumers’ blockchain technology sensitivity, commission rate and other parameters on the operation of green supply chain and the effect of government subsidies are analyzed. We find that regardless of blockchain cost subsidies or green production subsidies granted by the government, higher government subsidies and consumers’ stronger sensitivity to blockchain technology both can help improve the greenness of green products, the blockchain technology level, market demand, and increase the profit of manufacturers and E-commerce platforms. Moreover, regardless of the sales mode adopted, in addition to the greenness of green products, the effect of two different government subsidies on green supply chain is affected by consumers’ sensitivity to blockchain technology. No matter what subsidy strategies the government adopts, when the commission rate is low (high), the blockchain technology level and the greenness of green products are higher in the agency selling (reselling) mode, and manufacturers and E-commerce platforms are always affected by the commission rate and prefer different sales mode. The findings reveal the mechanism that how consumers’ sensitivity to blockchain technology and commission rates affect subsidy effectiveness and sales mode selection, and provide decision support for differentiated subsidy policy design and sales mode choices in green supply chains.
