政府补贴下双渠道销售与回收闭环供应链决策分析

摘要

Based on the double channel sales and recycling of closed-loop supply chain, the paper respectively sets up the decision model of supply chain without government subsidies and under government subsidy, and analyzes the influ-ence of channel competition of closed-loop supply chain. The analysis results show that the retail market share increases results in the increases of wholesale price, retail price and the retailer′s profit, and the decrease of the direct sale price;the increase of sale channel competition degree leads to increased sales price and profits of supply chain members;the in-tensify of recycling channel conflict makes the increases of retailer′s recycling price and manufacturer′s recycling quanti-ty, leading to the increase of manufacturer′s profit and the decrease of retailer′s profit;the increase of government′s recy-cling subsidies results in the increase of recycling price, recycling quantity and profits of supply chain members, and the recycling price, recycling quantity and profit of supply chain members with government subsidies are higher than those without government subsidies.%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。
