Abstract: This paper was based on the cobweb theory, using the logarithmic C-D production function and data from the statistical yearbook between 1994 to 2011, to take empirical analysis on animal husbandry output value, per capita net income of farmers, and the per capita pig sell quantity, maize yield which were the influencing factors of the fluctuation of pig production. And took theoretical analysis on the influence of the pig disease and government supportive policy. According to the results of analysis, drawing the influence coefficient of the pig production scale and the price of pig was 0.37 and 0.235, per capita net income of famers and maize yield did not have long-term stable relationship with pig production, then pig disease and government stable supportive policy were also the influencing factors of the fluctuation of pig production, finally put forward suggestions and countermeasures to stabilize the fluctuation of pig production.
