Research on financing strategy under the integration of green supply chain and blockchain technology

Green supply chain management (GSCM) has now risen to the strategic level of many companies. However, in practice, the introduction of green technology leads to the financial constraints for enterprises and there will be problems such as asymmetric information and low trust when enterprises adopt financing strategies. This paper builds a green supply chain model composed of a capital-constrained manufacturer and a retailer to study the impact of the application of blockchain technology on the manufacturer’s financing strategy. There are four financing strategies considered: no financing (NF) strategy, trade credit financing (TCF) strategy, bank credit financing (BCF) strategy and hybrid financing (HF) strategy. Through theoretical and numerical analysis of the impact of key parameters on the manufacturer's equilibrium financing strategy, we find that: there is no pure Pareto dominating financing strategy for this manufacturer. When the efficiency of blockchain technology investment is low, the NF strategy is optimal, while when the efficiency of blockchain technology investment is high, the TCF strategy is optimal. Base on these results, the green supply chains are suggested improving the investment efficiency of blockchain technology.
