Despite the continued development of alternative energies, fuel consumption is increasing. In particular, the price of gasoline fluctuates greatly according to fluctuations in international oil prices. Gas stations adjust their gasoline inventory to respond to gasoline price fluctuations. In this study, news datasets is used to analyze the gasoline consumption patterns through fluctuations of the gasoline inventory. First, collecting news datasets with web crawling. Second, summarizing news datasets using KoBART, which summarizes the Korean text datasets. Finally, preprocessing and deriving the fluctuations factors through N-Gram Language Model and TF-IDF. Through this study, it is possible to analyze and predict gasoline consumption patterns.

This study analyzed the impact of crude oil inventory while gasoline price adjusts to international crude oil price(WTI) fluctuations. We mainly focused on asymmetric relationship between crude oil and petroleum product prices and added oil inventory as an variable, using the error correction model which is based on Borenstein et al.(1997). This paper selected the sample period from January 1988 to December 2012, analyzed the asymmetry of each intervals and the influence of crude oil inventory to the degree of asymmetry changes, both full period and five years period respectively. The results showed that when considering crude oil inventory, existence and degrees of time amount asymmetry varies.

This study empirically analyzes that the asymmetry of domestic gasoline price adjustment to the crude oil price changes can vary depending on the level of gasoline price using quantile autoregressive distributed lag model. The data used are the weekly average Dubai price, domestic gasoline price at refiners and gas stations from the first week of May 2008 to the second week of October 2022. The study estimates three price transmission channels: changes in gas station gasoline prices in response to changes in Dubai oil prices, changes in refiners gasoline prices in response to changes in Dubai oil prices, and changes in gas station prices relative to refiners gasoline prices. As a result, the price adjustment of refiner's gasoline price with respect to Dubai oil price appears asymmetrically across all quantiles of gasoline price, whereas the adjustment of gas station prices for Dubai oil price and refiner's gasoline price tend to be more asymmetric as the quantile of gasoline price increases. Such a result is presumed to be due to changes in the inventory cost of gas stations. When the burden of inventory cost is high, gas stations have an incentive to more actively pass the increased buying price on their selling price.

정부는 지난 2월 22일 석유정제업자, 석유수입업자 등 석유비축의무자의 석유저장 및 비축의무이행에 관한 기준을 고시했다. 이 기준에 의해 유공 호남정유 경인에너지 쌍용정유 극동정유등 국내 5개 정유사는 정상적인 영업거래에 필요한 25일분의 운영재고량 외에 별도로 올해부터 오는 97년까지 매년 1일씩 모두 5일분의 민간비축량을 연차적으로 확보, 전체 비축량을 30일분으로 늘리도록 돼있다. 적용대상 비축물량은 원유 휘발유 등유 경유 중유 항공유 및 프로판 및 부탄가스등이다. 정유 5사의 석유비축량이 30일로 늘어나고 또 현재 거제와 여천등에 확장 또는 신설공사중인 정부비축량도 현행 25일분에서 60일분으로 증가하게 되면 오는 97년 국내 전체 석유비축량은 모두 국제 기준인 90일분으로 확대되게 된다.
