关税视角下跨境双渠道供应链的政府补贴策略

Government Subsidy Strategy of Cross-border Dual-channel Supply Chain from the Perspective of Trade Tariff

针对当前跨境电商贸易面临的国际关税壁垒和绿色壁垒问题,构建考虑政府补贴干预的跨境双渠道供应链模型,分析了关税视角下不同政府补贴策略对供应链成员决策以及利润的影响。研究表明:关税增加导致产品绿色度和供应链成员收益均降低;生产成本补贴下制造商的利润更高,但研发成本补贴下决定价格变化趋势的绿色化效率系数阈值更低,同时产品绿色度更优;固定补贴比例下政府补贴支出随关税和研发成本增加而减少,随消费者绿色偏好提高而增加。

In view of the international tariff barriers and green barriers faced by cross-border e-commerce trade,this paper constructs a cross-border dual channel supply chain model considering the intervention of government subsidies,and analyzes the impact of tariffs and government subsidies on the decision-making and profits of supply chain members.The results show that:the increase of tariff leads to the decrease of product greenness and supply chain members'income;the manufacturer's profit is higher under the production cost subsidy,but the threshold value of the green efficiency coefficient which determines the price change trend is lower,and the product green degree is better;under the fixed subsidy proportion,the government subsidy expenditure decreases with the increase of tariff and R&D cost,and with the green degree of consumers preference increases with the increase of preference.
