Abstract International transmission mechanism of agricultural product price fluctuation has become a hot topic in recent years. Understanding the rules of agricultural product price fluctuation is of great significance for government's to implement macro- control and reduce the adverse impact of international transmission mechanism of agricultural product price fluctuation on home market.Currently,the policy of most countries in the world is built upon the assumption of symmetric price transmission. However,a large number of empirical tests indicate that the symmetric price transmission is unrealistic in practice,on the contrary,it is asymmetry. The existing research is not yet complete,therefore,this paper makes a literature review based on the asymmetric perspective,and places emphasis on international transmission and asymmetric transmission of agricultural product price volatility.
