Biomechanical insights: Paths of change in the organizational model and operational mechanism of agricultural socialization services to meet farmers’ needs

In order to explore the change path of agricultural socialized service organization mode and operation mechanism to adapt to the needs of farmers, a fitness analysis framework is constructed based on biomechanics theory, and the operation characteristics of the organization mode are measured from the perspectives of mechanical equilibrium, resource flow and dynamic adjustment. Taking the North China Plain, the Middle Yangtze River Plain and the Northeast Plain as examples, we measured the density of socialized service supply, the resource flow rate and the fitness index, and the results show that the Middle Yangtze River Plain has the highest fitness index (0.83), the resource flow rate reaches 324.7 tons/day, the information transmission efficiency is 5.21 bit/s, and the response time to the farmer’s demand is the shortest (5.7 h), which indicates that the organizational structure is stable and the precision of resource allocation is high. Resource allocation precision is high. The biomechanics theory can effectively optimize the agricultural socialized service model and improve the adaptability and operational efficiency of the agricultural production system.
