Boxed Pigs Game Analysis on Raw Milk Resources Investment of Dairy Processing Enterprises in Cluster

摘要

With the development of Chinese dairy industry cluster, the competition of raw milk resource is getting keen between the dairy processing enterprises in cluster. Because the investment of raw milk foundation has the characteristic of public goods, dairy processing enterprises in the cluster can all benefit from the output, whether it makes investment or not, so the investment of raw milk resource are not efficient in economics. Game equilibrium of Boxed pigs is the common result of enterprises competition in low cost cluster. In this paper, the boxed pigs' game model is established to analyze the investment behavior of local and extraneous dairy processing enterprises. The analysis of the mode not only explains the reasons of boxed pigs' equilibrium, but also gives guidance for the improvement of the game equilibrium. Finally, the case of Heilongjiang province dairy industry cluster is studied. It is also shown that establishing self-owned pastures and building long term contractual relations with scaled dairy farms or dairy production associations can improve the game result, so as to reach the cooperation equilibrium.
