초록

본 연구의 목적은 한국채택국제회계기준 도입 전과 후를 비교하여 회계이익의 질의 향상여부와 도입 이후 기간경과에 따라 회계이익의 질이 향상되는지를 살펴보는 것이다. 본 연구와 선행연구의 차이점은 한국채택국제회계기준 도입 전 5개년과 도입 5개년을 비교하여 회계투명성과 자본시장의 반응이 향상되었는지를 살펴보고, 도입 후 기간 경과에 따라 회계투명성과 자본시장의 반응이 지속적인지를 살펴본다는 것이다. 본 연구의 표본은 2005년부터 2015년까지 유가증권 상장기업 중 12월 결산 법인을 대상으로 KIS-Value에서 자료를 수집한 9,339 기업/년 중 조건에 맞지 않는 기업을 제외하고, 또한 표본의 이상치가 분석결과에 미치는 영향을 배제하기 위하여 상하위 1%의 값으로 조정(Winsorization)하여 5,110 기업/년을 사용하였다.
본 연구의 연구결과 다음과 같다. 첫째, 한국채택국제회계기준 도입 후가 도입 전보다 재량적 발생액의 절대값이 작을 것이다는 가설 1-1의 검증결과 주요관심변수인 D_IFRS는 양(+)의 회귀계수값을 보이고 있으므로 한국채택국제회계기준 도입 후가 도입 전보다 재량적 발생액의 절대값이 작은 것으로 나타나 한국채택국제회계기준 도입 후 회계이익의 질이 향상되었음을 확인할 수 있었다.
둘째, 한국채택국제회계기준 도입 후 기간경과와 재량적 발생액의 절대값은 음(-)의 관련성이 있을 것이다는 가설 2-1의 검증결과 주요관심변수인 P_IFRS1은 양(+)의 회귀계수값을 보이고 있고, P_IFRS3, P_IFRS4는 음(-)의 회귀계수값을 보이고 있으므로 한국채택국제회계기준 도입 후 기간경과에 따라 회계이익의 질은 지속되고 있음을 확인하였다.
셋째, 한국채택국제회계기준 도입 후가 도입 전보다 이익반응계수가 높을 것이다는 가설 1-2의 검증결과 주요관심변수인 D_IFRS는 음(-)의 회귀계수값을 보이고 있고, 비기대이익과 D_IFRS의 상호작용 변수 모두 음(-)의 회귀계수값을 보고하고 있으므로 한국채택국제회계기준 도입 후가 도입 전보다 이익반응계수가 높을 것이다는 가설 1-2는 지지하지 않는 결과이다. 투자자들이 한국채택국제회계기준 도입 전과 후 회계이익과 관련된 정보를 투자의사 결정에 사용하는 점이 나아지지 않았음을 알 수 있다.
넷째, 한국채택국제회계기준 도입 후 기간경과와 이익반응계수는 양(+)의 관련성이 있을 것이다는 가설 2-2를 검증결과 주요관심변수인 P_IFRS2, P_IFRS3, P_IFRS4는 양(+)의 회귀계수값을 보이고 있으므로 한국채택국제회계기준 도입 후 기간이 경과할수록 이익반응계수가 높게 나타난다는 것을 의미하며 회계투명성의 증가로 투자자들이 이익과 관련된 정보를 투자의사 결정에 사용하고 있다는 것을 보여준다.

The purpose of this study is to take a look at whether the quality of the accounting profits improves and whether the quality of the accounting profits gets improved according to the passing of the time period after the introduction by comparing the before and after the adoption of K-IFRS. The point of difference between this research and the precedent researches is that the former takes a look at whether the accounting transparency and the reactions by the capital market have been improved by comparing the 5 years before and the 5 years after the introduction of the international accounting standards and takes a look at whether the reactions by the accounting transparency and the capital market are continuous according to the passing of the time period after the introduction. As for the samples of this research, the 5,110 corporations per year was used by adjusting (winsorizing) to the value of the upper and lower 1%'s in order to exclude the corporations that do not meet the condition of the 9,339 corporations during the year, the data of which were collected by KIS-Value with the corporations settling the accounts in December as the subjects among the listed corporations with the marketable securities from 2005 until 2015, and, also, in order to exclude the influences of the abnormal figures of the samples on the analysis results.
The results of this research are the following: First, as a result of verifying the Hypothesis 1-1 that said that the absolute value of the discretionary amount of the occurrence will be smaller after the introduction of the international accounting standards adopted by Korea than before the introduction, the D_IFRS, which is a key interest variable, has been showing a positive (+) regression coefficient value. Hence, the absolute value of the discretionary amount of occurrence after the introduction of the international accounting standards adopted by Korea was shown to be smaller than before the introduction. Therefore, we were able to confirm that the quality of the accounting profits had improved after the introduction of the international accounting standards adopted by Korea.
Second, as a result of verifying the Hypothesis 2-1 that said that the passing of the time period after the introduction of the international accounting standards adopted by Korea and the absolute value of the discretionary amount of occurrence have the negative (-) relationship, the P_IFRS1, which is a key interest variable, has been showing a positive (+) regression coefficient value and the P_IFRS3 and the P_IFRS4 have been showing the negative (-) regression coefficient values. Therefore, it was confirmed that the quality of the accounting profits has been continuing according to the passing of the time period after the introduction of the international accounting standards adopted by Korea.
Third, as a result of verifying the Hypothesis 1-2, which said that the earnings response coefficient will be higher after the introduction of the international accounting standards adopted by Korea than before the introduction, the D_IFRS, which is a key interest variable, has been showing a negative (-) regression coefficient value. And all the variables of the interactions of the unexpected earnings and the D_IFRS have been reported as having the negative (-) regression coefficient values. Therefore, it is a result that does not support the Hypothesis 1-2, which said that the earnings response coefficient will be higher after the introduction of the international accounting standards adopted by Korea than before the introduction. We can find out that the point that the investors use the information related to the accounting profits before and after the introduction of the international accounting standards adopted by Korea for deciding the investment intentions has not become better.
Fourth, as a result of verifying the Hypothesis 2-2, which said that there will be a positive (+) relationship between the passing of the time period and the earnings response coefficient after the introduction of the international accounting standards adopted by Korea, the key interest variables of P_IFRS2, P_IFRS3, and P_IFRS4 were showing the positive (+) regression coefficient values. Hence, this means that the earnings response coefficients appear higher the more the time period passes after the introduction of the international accounting standards adopted by Korea. And it shows that, thanks to the increase of the accounting transparency, the investors have been using the information related to the profits in making the decisions on the investment intentions.
