Stratification, Coordination and Integration of Agricultural Information Systems: Hangzhou Longjin Tea as an Example

Current agricultural information systems are constructed according to the supply chain model called ¿production-supply-sale¿, comparatively neglecting the characteristics of scale and financialization of agriculture. Comprehensive comprehension of agricultural informatization should be based on the characteristics of time and space of agricultural production through the whole process of production, which embodies the dumbbell-type structure of service-production-service. By constructing the interfaces of different processes, effective integration of different areas and procedures of informatization can exert the integration effect of the agricultural production service industry. This paper explains and analyzes the preceding theories by taking Hangzhou Longjin tea as an example.
