Currently construction corporations also is whether executing or planning IR activities as other corporation do. We will analyze correlation between stock price and IR activities and execute actual analysis of how IR activities influence stock price in order to identify positive influence of IR activities on Construction Corporations which are executing IR activities for raising capital and investors. We make two hypothesizes through searching thesis and interviewing experts. Two hypothesizes are as follows. First of all, stock price will increase in terms of public of IR activities. Second of all, IR activities targeted on domestic investors will be very successful. We deduce conclusions through verifying two hypothesizes. Conclusions are as follows. First of all, IR activities of construction corporations influence stock price positively. Second of all, IR activities targeted on international are more effective than on domestic Third of all, even though IR activities targeted on domestic is less effective than on international, it is indicated that it have positive influences.
