摘　　要：考虑制造商自主研发减排与外包减排任务两种情形,研究政府分别依据减排研发和单位产品减排量进行补贴下供应链的最优决策问题。从供应链制造商的角度,对给定政府补贴方式下,制造商的两种减排决策进行了对比,同时从政府的角度,在制造商特定的减排情形下,两种政府补贴方式的减排效果进行比较。进一步,通过数值仿真分析两种补贴方式下补贴系数对供应链决策的影响。研究结果表明,当政府采取依据减排研发的补贴方式进行补贴时,自主研发减排情形下制造商利润大于外包减排任务情形的利润;当政府采取依据单位产品减排量的补贴方式时,相比外包减排任务,制造商选择自主研发减排均能得到更多的减排量和利润。当制造商自主研发减排时,政府依据减排研发补贴方式比单位产品减排量补贴方式的减排效果更好,但利润较低;当制造商外包减排任务时,两种政府补贴方式的减排效果和利润均相等。通过数值仿真验证了以上结果,同时表明补贴系数对减排效果和利润具有显著影响。以上结论为政府制定合理的补贴方式及企业减排策略的选择提供了理论支撑。There have been a large number of fruitful work on supply chain decision-making considering government subsidies, but only the decision-making issues of manufacturers’ independent R&D emission reduction has been studied, and the production decision making when manufacturers outsource emission reduction tasks has not been considered. None of the literatures have explored the impact of different government subsidy approaches on manufacturer’s emission reduction options. In view of the above consideration, a three-level green supply chain is constructed that composed of suppliers, manufacturers and consumers to explore this issue. Considering the manufacturer investing R&D to emission reduction or outsourcing the emission reduction task, the Stackelberg game model is employed to explore the decision-making issue under the government subsidy approaches basing on emission reduction R&D investment or emission reduction amount of unit product in green supply chain.From the perspective of manufacturer, the manufacturer’s decisions of two actions for emission reduction are compared when given government subsidy approach. Secondly, from the government’s perspective, when manufacturer’s action is given, the effects of emission reduction between two approaches of government subsidy are compared. Further, numerical simulation is conducted to analyze the impact of subsidy factors on supply chain’s decision-making under two subsidy approaches. The results show that when the government adopts the subsidy method basing on emission reduction R&D investment, manufacturer’s profit of R&D emission by themselves is higher than outsourcing emission reduction task. When the government adopts the subsidies basing on emission reduction amount of unit product, the manufacturer’ profit and the emission reduction amount per unit of product in investing R&D to emission are more than the outsourcing emission reduction task. When manufacturer chooses to invest R&D to emission reduction, compared to subsidy approach of basing on
