Abstract: Based on the theory of information ecology, this paper studied the value creation and process optimization strategy of agricultural network information ecological chain, to improve the quality of agricultural information service and the utilization level of agricultural information. On the basis of expounding relevant concepts, it analyzed the elements and value dimensions of agricultural network information ecological chain, and constructed the value model of agricultural network information ecological chain. It concluded from the analysis that the agricultural network information ecological chain was a value chain, which relied on the internal information flow of each node in the chain, and finally realized the creation and appreciation of value.
