The purpose of this study is to analyze whether there are stable and unstable trends in landing prices and wholesale prices according to the change of volume of oyster in producing area. And if there is a dynamic causal relationship, this study can derive implications by analyzing the influence of mutual influence using VECM model. The data used in this study is monthly volume and price data from January 2008 to December 2018.
The main results were as follows. First, changes in production have had a positive impact on the changes in production and wholesale prices. It is reasonable to assume that the changes in the oyster farmers' production have led to a change in the oyster supply and demand status rather than a change in the spot and wholesale price. Second, changes in landing prices have a negative impact on changes in current production. This implies that oyster farmers can not control the amount of excrement and shipment by looking at the change in the price of producing area. The reason that as oyster demand and breeding status are different from each other, shipments are not easy to control.
