Abstract To determine the interaction among agricultural logistics demand, logistics supply, agricultural GDP and regional population in the modern agricultural logistics system of Jiangsu province, and analyze the impact of logistics information technology on the agricultural logistics system, the model of modern agricultural logistics system was constructed and optimized. The method of qualitative analysis was used with 13 evaluation variables, and the Vensim PLE software was used to draw the cause and effect diagram according to the relationship between each variable. The method of quantitative analysis was used to draw the system flow diagram according to the cause and effect diagram, and the system dynamics equation of each variable was established by Jiangsu statistical yearbook, China transportation development bulletin and SPSS data analysis software. The model was checked and simulated. The results show that when the proportions of investment in logistics information technology are increased by one, two and three times, the agricultural logistics supply quantities in Jiangsu province are increased by respective 2.25%, 4.49% and 6.73% on average, while the costs of agricultural logistics are decreased by respective 0.63%, 1.22% and 1.82% on average. Using modern information technology in agricultural logistics activities can make a positive impact on the entire logistics system.
