Dynamics Study on Forming Mechanism of Fluctuation Phenomenon in Hogs Supply Demand System

Causal effect feedback structure of hogs supply demand system was established by applying theories and approaches of system dynamics,etc. The special economic fluctuation behavior, e.i., stochastic type, permanent type, forward type, existing in the system was first described in integrative way. Then, taking that system in Zhejiang Province as example, with system simulation, the periodic fluctuation phenomenon was quantitatively demonstrated.
