Currently, the pig breeding mode dominated by individual households leads to acute fluctuation of pig price to some extent. The scale expansion of recent decade intensified the fluc- tuation of pig price in the short term but will stabilize the price in the long term. Therefore. it is necessary to expand breeding scale for maintaining long-term price stability and the optimal scale should be chosen according to the circumstances to ensure the social benefit maximization.展开更多
