On 18th Mar 2000, Mr. Chen, Shui-Bian in Democratic Progressive Party was elected to be the new president. Taiwan experienced the first powershift. However, many state-owned banks as well as some government-shared companies re-structured their board of directors continually. In the view of politics, the powershift will be normal in Taiwan in the future. So we try to survey the the effects of powershift towards re-elections of boards and firm performance of state-owned enterprises. We discover that the major reason why government wants to intervene the operations of companies is policy. If this kind of industry is regulated or monopolistic, the government will has stronger motives to intervene its operation. On the other hand, after being intervened by the government, the cumulative abnormal return declined significantly from the event day to thirty days later. Besides, the firm performance didn¡¦t improve significantly through the view of TobinQ, EPS and Market return. So we can say that this time of powershift didn¡¦t improve the poor condition of corporate and firm performance significantly. So Taiwan corporate governance should abandon the relationship-based economic model and stride to the talent-based model.

<p>The purpose of this study has been to examine how customers, by interacting with each other, can communicate and create the image of a brand. We find this topic to be relevant since there are no previous studies conducted concerning the customers influence on the brand image. Our ambition has been to describe in what ways and to what extent the customer can affect and influence the brand image by communicating with other customers. To fulfill our purposed we have targeted three important questions which are:</p><p>• In which ways can the customer affect the communicated image of a brand?</p><p>• To what extent can the customer influence the brand image and the perceived value?</p><p>• Who has control over the brand, the customer or the company?</p><p>For this study we have used a qualitative approach in which we have conducted eight personal interviews with brand consultants and the editor of the magazine Dagens Media which has given us the foundation for our analysis. We choose this qualitative approach to gain a deeper understanding and a complete picture for the studied topic. In the final chapter we present our conclusions of the study. We have found that consumers can influence and communicate the brand image in five different ways; by using the brand, through word-of-mouth, buzz, engaging in social groups and through Consumer Generated Media (CGM). Another conclusion we have drawn is that the consumer has gained more control over the information flow in the market and thereby their ability to affect the company’s marketing message has increased. The main reason for the consumers improved power is the explosion of media channels that has developed and increased through Internet. Finally we have drawn the conclusion that the brand image can be divided in to two different aspects; the personal and the general image.</p>
