Abstract: This research study is concerned with the analysis of the Bangkok Metropolitan Administration’s (BMA) district offices using the Linear Structural Model (LEM) to determine the variables that affect public sector organizational performance. Three hundred and forty quantitative samples were drawn from all 50 of Bangkok’s BMA districts using simple random sampling (purposive sampling) while using Partial Least Square (PLS-Graph) software to apply Structural Equation Modeling (SEM) analysis.The research found that there are three factors determining BMA’s strategy. They are public sector marketing factors, transformational leadership and organizational strategy. The first element, public sector marketing factors has a direct and positive influence on BMA’s performance. The second, transformational leadership has been shown to have a positive although, indirect effect through variables in their organizational strategy. It was also discovered that organizational strategy able to keep pace with the flow of change and how to run a modern government efficiently and flexibly were crucial factors as well. These were important in achieving the goals of satisfying the constituency and optimizing public sector resources.
