POS 자료를 활용한 쌀 소비지가격과 산지가격의 인과성 분석

Abstract

Rice is possible to use POS data because it is mostly selling with the same bar-code system from producers to large retail stores. This paper analyzes the selling structure of the rice retail market and investigates pricing mechanism between large discount stores and RPCs using POS data. The study results show that RPC’s selling price and discount stores' retail price in regard to low-value rice affect with each other but have statistically no correlation for high- value rice products. This means that with respect to low-value rice, large discount stores bargain with RPCs and consider the situation of producer price to set the purchase price, but high-value rice product is not much affected by price variation.
