The securitization regulations of the real estate were announced and implemented on July 23, 2003. These improve the mobility of real estate in Taiwan. There are two kinds of forms, the investment trust of real estate (REITs) and real estate assets trust (REATs). U.S.A is the. most developed country for REITs, and the experience in Japan can give us some important reference. This research hopes with discussion and analysis of some cases of our country and then consults the real estate securitization systems of U.S.A., Japan, Hong Kong, etc.; one can put forward the view and suggestion on the influence that the financial institution operates on the securitization of the real estate. In the securitization operation course of the real estate , manage the rule etc. in decree including Trust Law , trust business law , bank law and trust and investment corporation involved . The securitization can be assigned to enterprise's financial securitization and securitization of the assets, and the assets securitization can be divided for securitization and securitization of the real estate of financial assets. The main purpose includes promoting the effective use of the real estate, promote the effective use of the fund, improve and raise the environmental quality of the essence, prevent the land resource from to control, prevent land speculation from, perfect the market function, disperse the investment risk, solving the problem of financing for the financial group, large-scale production of reaching the real estate and managing. Its characteristic, for circulation, cashing, fairness, specialized, disperses the risk. The main difference of REITs and REATs is that there is fund and securitization with REITs first, then invest in the real estate and relevant right, but REATs is to enable assets possessors to obtain the fund through the securitization, reduce the real estate and hold the quantity. The securitization of the real estate originated from U.S.A., was the place where the whole world develops REITs earliest, legal system is complete, the diversification of the goods. Till the end of January of 2006, there are listing REITs 198 Companies in all, total market value is 358,400 million dollars, the rights and interests type have absolute predominance. The Japanese real estate securitization was implemented formally in November of 2000, 32 are listed till March of 2006, the total about 3.26 trillion days of market value round. Hong Kong REITs market just belonged to the starting stage, own 3 in common begin to merchandize till the end of March of 2006, it up to 23,500 million Hongkong dollars to raise the scale of the money, yet there is large one and will be listed on Hong Kong soon in the reservation, Hong Kong will become the second largest REITs market in Asia, is second only to Japan. And the investment trust system of real estate of our country consults U.S.A. mainly, the assets trust of the real estate draws lessons from Japan. Till the end of December of the 94th year of the Republic of China, already there are securitization goods of 10 pieces of real estate that have checked and approve to issue at home, among them 7 departments regard REATs as the structure, 3 departments issue and are listed by way of REITs. Domestic the real estate securitization to last only more than two years, its still some subjects in the course of decree clause and operation deserve the discussion , including REITs is it issue , REITs business transaction ,etc. agreement of amount of money standardize stipulate , pluralistic issue of source that REITs mark of standard ,etc. to add to. Implementation of the securitization of the real estate, it influences the aspect to relevant industry extremely widely, cause the influence analogous to the degree on the traditional business of the financial institution. The securitization of the real estate has changed the way in which the fund raises of the past, has also produced the change to the form of operation and administration of the real estate market. And the influence on the business of financial institution, in terms of banking, it is served as and is commissioned the organization that there are its positive benefits, investment tool increase , underwriting , self-operation , brokerage of marketable securities , develop investment bank , reverse side influence for storing original , loan business reduce. From the angle of the securities business, its role's function is roughly consigned to roles of functions , person who makes city , serving as financial advisor , the mobility of the financial goods fixing the price and designing , secondary market , educational investor ,etc.. From the angle of the insurance, role that can serve as it, take on original organization, investor, trust business, real estate management organization, credit strengthen insurer, etc. role. But in the course of securitization operation of the real estate, there must also be good control systems, guarantee that the relevant interested party's rights and interests are not injured. Control the system , is divided into three kinds , such as inside control system , external finance managing , financial market's own self-containment ,etc. on the whole . The securitization market of the real estate will step into the stage growing up fast, will grow up the space very big in the future, will attract more investor's input, in order to ensure investor's rights and interests, the relevant mechanism, with should be set up to form a complete set as quickly as possible, give investors more reeducation, the construction of the information platform of investment, every trade agreement melts simple and easily and makes clear etc.. The developing real estate securitization will be revised open soon; the competent authority should bear and verify the heavy responsibility. The innovation ability of the financial institution will also face the test , a piece of a large amount of real estate securitization goods coming one after another, how the financial institution weeds out the old and brings forth the new, obtains to investors and favors, it is a decisive key of the future. The domestic efforts in this respect of financial institution still remain to strengthen. The development of the securitization of the real estate will move towards the internationalization too unavoidably, integrate with the international capital market, should be adjusted too while managing the norm. Future, real estate securitization apply city newer, public construction, non-performing assets, etc. to, the operation course is quite professional, tedious, every financial institution should train every qualified personnel in a specific field actively, develop the administrative system of the assets, set up and perfect the inside control system, and set up and specialize in the department to promote the securitization business of the real estate.
