Company size was found to be a significant in influencing company performance. Company size could increase company performance through economic of scale. Perhaps, in an emerging market such as Indonesia, size plays a significant role in influencing company performance due to the presence of greater economies of scales, better competitive position, having more skilled managers, and having greater access to cheaper sources of funds.
