董事會多元化與盈餘管理之關聯性分析

摘要本研究旨在探討董事會多元化(性別、任期、國籍、董事兼任總經理程度及彙總之綜合指標)與盈餘管理之關聯性分析，研究以2014年至2018年之台灣上市上櫃公司為研究對象。實證結果發現，董事會多元化綜合指標程度愈高，愈能抑制公司進行盈餘管理，另以各董事會多元化特性檢測，顯示董事會性別多元化、董事會任期多元化、董事會國籍多元化、董事會兼任總經理程度愈高，愈能抑制公司進行應計盈餘管理，但董事會兼任總經理程度對應計盈餘管理效果不顯著。而董事會性別多元化、董事會任期多元化愈高，愈能抑制公司進行實質盈餘管理，但董事會國籍多元化、董事會兼任總經理程度不會顯著影響實質盈餘管理。此研究整體而言表示，董事會結構及成員愈多元化，會減少公司進行盈餘管理。

Abstract The purpose of this study is to explore the correlation between board diversity (gender, tenure, nationality, degree of director and general manager, and aggregated aggregate indicators) and earnings management. The study is based on Taiwan-listed and over-the-counter (OTC) companies from 2014 to 2018. . The empirical results found that the higher the comprehensive index of board diversification, the more inhibited the company ’s earnings management. In addition, the board ’s diversity characteristics were tested to show that the board ’s gender diversity, board tenure, board nationality, and the higher the degree of the board of directors as the general manager, the more the company can be restrained from performing accrued earnings management,but the degree of the board of directors as general manager is not significant for the accrued earnings management. The gender diversity of the board of directors and the higher the board's term of office, the more it can inhibit the company's actual earnings management, but the diversity of the board's nationality and the degree of concurrently serving as the general manager of the board will not significantly affect the actual earnings management. The study as a whole stated that the more diverse the structure of the board of directors and members, the less profit management the company will have.
