Two indicators, Concentration Ratio and Herfindahl Index, were used to measure the level of Concentration of petroleum retail market. In addition, many factors included market share,number of service station,advertisement,assets and government policies were determined to study the cause-effect of the Concentration among four major companies, PTT, Shell, Esso and Caltex. From the study, Concentration ratio of the four major companies of gasoline and premium gasoline (plus ulg) trended to decline continuously. This was also applicable for high speed-diesel but the lower rate. The factors that impacted concentration ratio are classified into two categories, company factors and government policies.

However, advertisement seemed to be reduced and this effect market portion of petroleum retailing business. According to the study,government policy was a significant impact of Concentration. After liberlizing petroleum business, the concentration ratio was reduced caused by more new entrances.
