The Optimization of Supply Chain Financing for Bank Green Credit Using Stackelberg Game Theory in Digital Economy Under Internet of Things

The aim is to improve small and medium-sized enterprises (SMEs)' core competitiveness financing attainability using deep learning (DL) under economic globalization.
