Abstract: According to the development trend of Chinese regional economy‚and with the organic combination between the basic principle of system dynamics and modern logistics‚a new idea and the corresponding modeling method of system dynamics of regional logistics were investigated．Then‚according to the characteristics of the system dynamics model‚the mathematical equation of the system was deduced．By the analysis of logistics system of the Pearl Delta area‚the practicability of the model and the instructional meaning of the theory were proved‚which provides a new research direction for the integration and harmony of regional logistics system．

Key words: regional logistics, system dynamics model, logistics system analysis
