I managed to make a study of the relationship between the information transparency and disclosure channels of listed companies, because the selection of disclosure channels for the correction of United Microelectronics Corporation’s (UMC) financial statement stirred up a violent argument that the foreign investment institutes gained profit by selling out UMC’s stocks promptly thanks to UMC’s using Business Wire to distribute its information while local securities investment trust enterprises and securities dealers lost a lot of money due to information lag.
