Abstract：In recent years，logistics and e- commerce play an increasingly important role in the supply chain of agricultural products. The coordinated development of the two will not only affect the development level and quality of each other，but also affect the smooth operation of the whole supply chain of agricultural products，thus affecting the stable development of agriculture and rural economy. The authors analyze the composition and basic structure of the agricultural product supply chain system. From the perspective of complex system，using the research ideas and methods of synergetics，taking the complex system composed of logistics and e- commerce in the agricultural product supply chain as the research object，the authors construct the analysis framework of the coordination mechanism of the complex system. The key point is to analyze the self-organization evolution of the system through the establishment of differential equation mathematical model. The stability conditions for the system to reach cooperative state are solved. By solving the differential equation，it is concluded that the stable balance condition of agricultural products logistics and e- commerce depends on the positive contribution effect and negative influence effect between agricultural products logistics and e- commerce. Based on this，the order parameters of agricultural products logistics and e- commerce collaborative system，including macro order parameters and micro order parameters，are identified according to the factors that determine the contribution effect and influence effect. According to the principle of synergetics，the authors consider that the micro order parameter is the key factor that affects the realization of the coordination of the complex system，and the bottleneck order parameter that determines whether the system can realize the coordination. It can push the self-organization process of the system to approach the collaborative state by applying external intervention to the micro order parameter，while the macro order parameter reflects the state of the self-organization process of the system. Therefore，combined with the identified macro order parameters， select the corresponding indicators to form the order parameter index set，and further build an evaluation model to measure the degree of coordination between China's agricultural products logistics and e-commerce. Through this model，the index data from 2013 to 2018 are analyzed. The analysis results show that although the development speed of China's agricultural products logistics and e-commerce is very fast in recent years，the situation of collaborative development between them has been in a state of extreme maladjustment，which is in the dynamic evolution process of mutual competition and cooperation. It is far from reaching a stable balance of coordination，which also shows that there is still a lot of room for improvement in promoting the coordination of agricultural products logistics and e- commerce in China. In view of this situation，the authors put forward that we should try to stimulate more demand for agricultural e-commerce，increase support for 3PL of this industry，strengthen strategic coordination， and strengthen information integration，and improve the information sharing among agricultural product logistics and e-commerce. Improvement suggestions around three micro order parameters of agricultural products logistics and e- commerce collaborative system，namely，logistics bottleneck，partner loyalty and information sharing degree.
