Large scale is the direction of pig- producing development of China in future, but does not mean breeding scale the bigger the better. The rationality, scientificalness and suitability of each region pig- producing scale has determined the effectiveness of pig-producing to a large extent. This paper shows that, from the national average level to see, the moderate scale has the strongest profitability.
