Evolutionary Game and Numerical Simulation of Enterprises’ Green Technology Innovation: Based on the Credit Sales Financing Service of Supply Chain

In the context of economic transformation and ecological civilization construction, breaking financing constraints carrying out green technology innovation has become an urgent task for enterprises to achieve sustainable development in China. As a method supply chain, can credit sales effectively promote enterprises’ innovation? This paper constructs evolutionary game model between upstream downstream enterprises. Firstly, interaction is explored through equilibrium analysis. Secondly, influencing factors decisions are analyzed numerical simulation. The study found that: (1) Under condition equilibrium, form virtuous circle mode “financing—income generation—benefit sharing”. That is, win-win situation be achieved internal circulation chain. (2) Profit distribution one key issues willingness provide carry positively related benefits they enjoy from innovation. (3) supervision cost obstacle sales. A practical inexpensive account recovery guarantee mechanism effective way improve (4) government’s subsidy beneficial whole chain’s “credit sales—green innovation” mode, which not only directly stimulates but also benefit sharing. enriches relevant research on chain provides reference
