基于双渠道销售和回收的闭环供应链,本文分别建立无政府补贴情形和有政府补贴情形的供应链决策模型,分析渠道竞争对闭环供应链的影响,比较政府补贴前后供应链决策的变化,探析补贴的变化对供应链效率的影响。结果表明:零售渠道市场份额的增加使批发价格、零售价格以及零售商的利润增加,直销价格降低;销售渠道竞争的加剧使渠道销售价格和供应链成员的利润增加;回收渠道冲突的加剧使零售商回收价增加,制造商的回收量增加,并导致制造商的利润增加而零售商的利润减少;政府给予制造商单位废旧产品回收补贴提高,回收价格、回收量以及供应链成员的利润也相应提高,且高于无政府补贴时的水平。
Based on the closed-loop supply chain of dual-channel sales and recycling, this paper respectively establishes the supply chain decision model without government subsidies and government subsidies, analyzes the influence of channel competition on the closed-loop supply chain and compares the changes of supply chain decisions before and after the government subsidies Impact of changes in subsidies on supply chain efficiency. The results show that: the increase of retail market share leads to the increase of wholesale price, retail price and retailer profit, the direct selling price decreases; the competition of sales channel increases the sales price of channel and the profit of supply chain members; the intensification of recycling channel conflict makes retail Increased merchant replenishment rates, increased manufacturers’ reclaims, increased manufacturer profits and reduced retailer profit margins. The government has given manufacturer units higher subsidies for the recycling of used products, as well as recycling prices, recoveries, and profits of supply chain members Increase, and higher than the level of government subsidies.
