摘　　要：利用博弈论探讨了异质性创新下不同政府补贴策略对绿色供应链创新绩效的差异性影响。假设供应商进行边际成本密集型绿色创新(MIGI),而制造商为研发密集型绿色创新(DIGI),分别建立并求解了独立创新补贴(IM)、联合创新且分别补贴制造商和供应商(UG)、联合创新且完全补贴制造商(UMI)、联合创新且完全补贴供应商(USI)四种政府绿色补贴模型。研究发现:联合创新下的产品绿色度一定高于独立创新,且随补贴程度的增大加速上升。政府补贴仅会提升USI模式下的费用分担比例,因而USI模式下制造商的绿色创新程度高于UMI和UG模式,而供应商的绿色创新程度在三种补贴模式下均相同。无论是从产品绿色度、供应链经济效益还是社会总福利的角度,USI模式均最优,其次是UMI和UG模式,IM模式最次。若把环境规制成本考虑在内,政府补贴净收益并不一定在USI模式下达到最佳。This paper uses game theory to explore the differential impact of different government subsidy strategies on the innovation performance of green supply chains under heterogeneous innovation.It is assumed that suppliers conduct marginal cost intensive green innovation(MIGI) while manufacturers conduct R&D intensive green innovation(DIGI).This paper establishes and solves four kinds of government green subsidy models: independent innovation subsidy(IM),combined innovation and subsidized manufacturer and supplier respectively(UG),combined innovation and fully subsidized manufacturer respectively(UMI),combined innovation and fully subsidized supplier respectively(USI).The results show that the greenness of products under joint innovation must be higher than that of independent innovation, and it will accelerate as the subsidy increases.Due to the difference in the cost structure of innovation between suppliers and manufacturers, government subsidies will only increase the cost-sharing ratio under the USI model.Therefore, the green innovation level of manufacturers under the USI model is higher than that of the UMI and UG models.However, the degree of green innovation of suppliers is the same under the three subsidy models.The USI model is the best in terms of social green effect, supply chain economic benefits, or total social welfare, followed by UMI and UG models, and IM model is comparatively the worst.If the cost of environmental regulations is taken into account, the net income of government subsidies may not be the best under the USI model.
