The aim of this paper is to find the relationship among different leadership styles (LS), organizational learning (OL) and organizational performance (OP). It's no doubt that quality is also very important for OP. Since the 1980s, total quality management (TQM) has been measured as a standard for good product quality. A great deal of effort has been made to find the influence of the above factors. However, it is a new approach to consider four factors in the model together. So the purpose here is to explore a little further into the causal relationship about LS, OL, TQM and OP in the structural equation model (SEM). This study is focused on the hi-tech firms in Hsin-Chu City, Taiwan. We can use three-layer research structure to create a convenience sampling survey. Finally, it’s proven that LS is a critical factor to form the OL, and OL has a direct influence on implementing TQM. Both OL and TQM also show direct influence on OP. However, the relationship between LS and OP is not significant; nor are LS and TQM implementation. This paper hopes to give all hi-tech firms in the world an empirical study to reconsider their business model.
