Comparison and Optimization of Circulation Modes of Fresh Agricultural Products Based on System Dynamics—The Case of China

摘要

High efficient circulation of fresh agricultural products plays a significant role in national new urbanization construction. To enhance the stability and improve the efficiency of the supply of fresh agricultural products in urban, this paper constructed a system dynamics model of regional circulation of fresh agricultural products to quantitatively evaluate the efficiency of the six types of circulation modes, based on the SWOT analysis of wholesale market mode, agricultural leading enterprise mode, third party logistics mode, E-commerce mode, super market docking mode, and farmer direct selling mode. The WT-optimization strategy was simulated through overcoming their own shortcomings and coping with external challenges. The results showed the circulation efficiency rank of fresh agricultural products: wholesale market mode = farmer direct selling mode > farm-supermarket docking mode > agricultural leading enterprise mode > E-commerce mode > third party logistics mode, and on the optimization strategy aspect, the supply efficiency of fresh agricultural products would be developed through reducing the delay of procurement and enhancing the ability of sales and procurement efficiently.
