供应商资金约束下考虑政府补贴的供应链绿色生产决策研究

基于中小供应商面临资金约束的现实情境,将政府绿色信贷和绿色产品补贴引入供应链绿色生产决策系统,建立政府、制造商、供应商博弈模型,分析供应链最优绿色生产决策。研究表明:①提高消费者绿色敏感度有助于企业扩大生产、提高产品绿色度,在一定范围内增加社会福利;②降低供应商绿色投入占比会在缓解融资压力的同时增加社会福利;③绿色信贷补贴下,绿色敏感度的提高增加了融资压力,但绿色产品补贴下,仅当绿色敏感度较低时此结论才必然成立;④当绿色敏感度较低时,绿色信贷补贴更能激励绿色生产,改善社会福利水平,反之绿色产品补贴更优。

Research on Green Production Decision-Making of Supply Chain Considering Government Subsidies under Supplier Capital Constraints

In response to the practical dilemma of capital constraints faced by small and medium-sized suppliers,the study introduces government green credit subsidy and green product subsidies into the green production decision-making system of supply chain,establishes a game model composed of the government,manufacturers,and suppliers,and analyzes the optimal decision-making.The results show that:First of all,the improvement of consumers’green sensitivity is conducive to promote enterprises to expand production,improve the greenness of products,and increase social welfare to a certain extent.Secondly,reducing the proportion of suppliers’green investment can not only relieve the financing pressure,but also increase social welfare.Besides,in the case of green credit subsidies,the improvement of green sensitivity brings greater financing pressure,but in the case of green product subsidies,this conclusion is only true when the green sensitivity is low.Finally,when green sensitivity is low,green credit subsidies can better stimulate green production and improve the level of social welfare,on the contrary,green product subsidies are better.
