Real estate brokerage has gradually progressed from growth to maturity since management regulations were executed. Since the government has ensured consumer rights by legislations, the confidence of consumers in real estate brokerage has been greatly enhanced. The success ratio of real estate cases has therefore increased. In addition, for the past two years, the economy has been recovering and the government has continued in its policy of subsidizing house loan interest. Real estate brokerage has therefore been highly prosperous for these two years. The internet has developed rapidly, and it is changing transaction modes in many industries with its low costs and capacity for rapid information transfer. It also puts industry leaders in a stronger position. The rules of the game have changed in industry. Corporations have to reevaluate business modes affected by the internet and consider the resultant changes. The character of real estate usually complicates transactions and thus influences the actions of buyers and sellers. The transaction therefore has many variables. Moreover the buyers are not aware of all of these variables. The brokers usually take advantage of the buyers¡¦ relative ignorance for their own professional gain. What is the brokers¡¦ advantage in this situation of information disparity? How do they utilize this advantage? In this study these questions will first be clarified and expounded. It will then be investigated whether the influence of the internet will lessen the need for professional intermediation or the brokers¡¦ information advantage. Finally comparisons will be made between the pre- and post-Internet world. Sinyi Realty Inc. is the only listed real estate company in Taiwan at present. According to Commonwealth Magazine market survey Sinyi Realty Inc. is the most trusted and best-known company in real estate brokerage. It even has the highest sales figures in the industry. In addition Sinyi Realty Inc. is the only real estate company ranking in the Taiwan Top 500. For these reasons it has been singled out as a case study for in-depth research in order to evaluate the possible influence of the Internet now and in the future. This study will begin with the analysis of Sinyi Realty Inc.¡¦s development background and competitive advantages followed by the internal and external changes arising from the Internet¡¦s influence. Finally the potential advantages, disadvantages risks, and opportunities will be studied and analyzed. It is hoped this study can act as a reference for real estate brokers as they formulate their development strategies in the Internet-influenced world of the future.
