This thesis investigates whether and how level of resource explain variation in the persistence of a firm`s competitive advantages. In oiler to test our hypotheses, we developed an instrument to measure three attributes of resource ; firm`s competency, causal ambiguity and isolating mechanism, and collected data within domestic industry. We found that the competency, causal ambiguity of resource prolongs performance advantages through isolating mechanism and knew that the isolating mechanism is associated with sustain advantages. This study contributes to the strategic management literature by providing evidence on the validity of a core, but largely untested proposition of resource-based theory : that inimitable resources, rather than market entry harries, often explain the persistence of superior financial performance. Our findings both support and qualify the resource-based logic. In addition we begin to resolve a tension that exists between resource-based theory and research on foreign direct investment. Finally, resource-base theory highlights isolating mechanism an particularly attractive source of competitive advantage. Yet isolating mechanism is rarely measured and related to a firm`s performance advantage. This study presents a method of measuring isolating mechanism that is directly linked to the performance outcome a firm seeks to compete on.
