초록

본 논문에서는 상품시장 경쟁 압박과 경영자의 이익관리 간에 유의적인 연관성을 가지고 있는가에 대해서 실증 검증한다. 기존 연구에 의하면 시장의 경쟁 강화로 인하여 상품시장 가격결정 방법은 원가 충격을 기업이 소비자에게 이전시킬 수 있도록 하는 완충장치의 작동원리로써 작용할 수 있다는 것이 설명되었다. 또한 인위적인 이익관리는 시장기대에 부응하기 위하여 약한 가격 결정력을 가진 기업이 하는 것이고, 이익관리를 통해서 경쟁적 우위 유지를 위해 경쟁자에게 왜곡된 정보를 전달하는 유인이 존재한다는 것이다. 따라서 경쟁적 압박이 많은 기업일수록 경쟁 상태에 있는 기업에 활용 가능한 정보의 제한을 통해서 이익관리를 할 유인이 존재함을 알 수 있다. 이 같은 기존의 연구가 국내 거래소 시장에 상장되어 있는 비-금융기업에서도 발견되는지를 실증 검증한다. 본 연구결과에 의하면 다음과 같은 결과를 도출하였다. 상품시장에서 높은 가격 결정력을 보유한 기업은 재량적 이익 발생액에 대하여 낮은 성향이 존재하며 이 같은 결과는 기업 재무제표의 질 및 신뢰성과 투명성을 파악하는데 또 다른 요인이 된다. 즉 강한 경쟁 산업에서 더 많은 이익의 조정이 상대적으로 높게 나타나고 있는 것을 발견할 수 있다. 이와 같은 결과들은 미국의 연구결과와도 일치하는 것으로 나타난다. 본 연구의 실증결과에서 상품시장 가격 결정력과 경쟁을 기반으로 한 기업 이익의 질과 정보에 대한 의미를 분석할 수 있는 동기가 된다.

Abstract

We investigate whether there is relationship between product market competition and earnings management using non-financial firms listed in KOSPI market over periods of 1981 to 2015. Suggested hypotheses are as follows: First, we conjecture that there is strong association between pricing power of product market and earnings management. Second, also we conjecture that there is strong association between industry competition and earnings management. Based on these hypothesis, empirical test results are as follows: The firms with high pricing power in product market tend to have lower earning accrual. This result implies that it provides new factor to better understand the quality of financial statement and transparency of financial statement. This means that firms in high product market competition could have high earnings management relative to firms in low product market competition. This empirical evidence is consistency to evidence of U.S firms. As a result, we suggest that this evidence provides the direct implication for understanding quality of earning and information of financial statement with regard to product market competition. This study is summarized as follows. First, it is shown that discretionary accruals are lowered as the pricing power is higher as a result of the empirical test on how the effect of discretionary accruals is influenced by the substitution variable EPCM of individual firm pricing power. In other words, it suggests that firms have more incentive to manipulate more profits than in more competitive situations and that the quality of profits is lowered. Second, discretionary accruals are lowered as the HHI index, which shows industry concentration, shows lower. As a result, the higher the industrial competitiveness, the higher the discretionary accruals. Third, the analysis using the number of competitors in the industry shows that discretionary accruals become higher as the number of competitors increases. This shows that the more competitive the industry, the lower the quality of the profits. From the viewpoint of managerial strategy, companies that fail to secure a competitive advantage under market competition will need to strengthen their pricing power by securing a competitive advantage, which will lead to enhanced transparency and reliability of the company’s financial statements. It is necessary to establish a management strategy for a competitor considering the competitiveness of the competitor in analyzing the financial information of the competitor, in order to meet the expectations of the market and to maintain the competitive advantage through the artificial profit management.
