The sample was 300 palm oil entrepreneurs in Southern Thailand listed in the database of the Department of Internal Trade, Ministry of Commerce of Thailand, arisen from 20 times of the variables in the research model and stratified random sampling by area, divided into upper and lower southern regions. The research instrument was a questionnaire. The statistics used for data analysis were frequency, percentage, mean, standard deviation, confirmatory factor Analysis, and structural equation modelling. The results showed that the SCM, LSC, and LP were at a high level. In addition, SCM had a positive direct effect on LSC and LP and had a positive indirect effect on LP by the mediation effect of LSC. These findings can be guidelines for palm oil entrepreneurs to improve the business's logistics performance.
