VERIFICATION OF FISH PRICE IMPROVEMENT EFFECTS IN SANITARY MANAGEMENT TYPE FISHING PORTS BY STATISTICAL ANALYSIS METHOD

Abstract

 In recent years, there has been an increasing interest in food safety and security, and sanitary management type fishing ports have been developed in many production areas.

 The purpose of this study is to conduct a “difference-in-differences” analysis, which statistically analyzes causal relationships, in addition to the conventional data analysis, to clarify the effects of sanitation management measures on fish price changes. We were able to quantitatively evaluate the effects of hygiene management measures.
