Green Supply Chain Pricing and Investment Strategy Considering Government Subsidy Ways from a Dynamic Perspective
In the process of green development transformation of supply chain enterprises,the way of government subsidy will affect the pricing and investment decisions of supply chain members,and the dynamic change of product greenness will increase the difficulty of decision-making.Based on this,considering that product greenness is affected by time factor,two differential game models of green supply chain under different government subsidy ways(unit production subsidy or green R&D subsidy)are constructed to study the influence of government subsidy ways and subsidy intensity on dynamic pricing and investment strategy of the supply chain.The results show that:When the initial value of product greenness is low,regardless of the value of government subsidy coefficient,enterprises choose penetration pricing strategy and increase the level of green technology investment.When the initial value of product greenness is high,there is a threshold value of government subsidy coefficient,which makes enterprises change from skimming pricing strategy to penetration pricing strategy,and correspondingly reduce and then increase the level of green technology investment.Under the same government subsidy expenditure,the green R&D subsidy way is better in improving the product greenness,increasing economic profits,environmental benefits and social welfare,but it will lead to higher sales price.When the operation of the enterprise reaches a stable state,the efficiency of government subsidy is 0,that is,the long-term green subsidy is not sustainable,at which time the government should implement an appropriate subsidy retreat strategy.
