摘要：This working paper presents objectives, methods and the empirical basis of the international working group InterPIG. The members of the group act within an informal network as a base for a mutual exchange of data needed for a unique way to annually calculate the costs of pig production and to analyse their determinants. The working paper informs on the contributions of the members to the network, explains the method for calculating the production costs and presents results of 2006. Further, it shows how InterPIG can react to rapid price changes like the increase of the feed prices during 2007
