Abstract: Based on the status of pig farming in Heilongjiang Province, using Cobb- Douglas production function, input and output indicators of pig farming were selected, and scale economies models were built. Through empirical analysis, it could be concluded that the number of breeding pigs in Heilongjiang Province was an important factor affecting scale economies. When the scale of pig farming above 100 or more, increasing returns would be achieved. Suggestions were put up from rational planning, policy support, strengthening services in order to improve scale economies of pig farming in Heilongjiang Province.
