How to Improve the Quality of Raw Milk in China

摘要

At present, raw milk is mainly supplied by smallholder dairy farmers or small-scale feeding bases in China. Considering liquid characteristics of raw milk and its current acquisition mode, the paper analyzes the feasibility of quality improvement cooperation between the dairy farmers and processing companies by the means of Multi-groups replicator dynamics model, supposing the processing companies provide techniques support to dairy farmers for the quality improvement of raw milk. This paper explores the strategy choices of dairy farmers and processing companies, and also investigates the main factors of cooperation between the two groups. Results show that the two groups' strategic choices are not only affected by the incomes change caused by quality improvement of raw milk, but also influenced by the R&D costs or execution costs of the techniques. Finally, we present some suggestion to promote the cooperation between the two groups.
