摘要
以沪深股市ERP(企业资源管理系统)用户为样本,观察ERP是否影响了盈余质量。由于用户管理层持股比例偏低、股权集中度较高、股权制衡能力较弱,使得ERP内部使用者——管理层有较强的盈余操纵动机;ERP技术的先进性,为用户操纵盈余提供了便利。因而,ERP应用可能加剧用户的盈余操纵,降低盈余质量,这一假设得到实证支持。与已有研究不同,考虑了ERP使用者动机;选取与会计基础相关的可操控应计指标、与市场相关的盈余反映系数、会计稳健性指标多重检验;以新兴经济体国家中国公司为样本,改变了国际上主要研究美国情况局面。建议管理层、审计师、股东、监管层及相关人员在评估ERP系统及目前正在实施的XBRL(可扩展商业报告语言)效果时,考虑使用者动机的影响。
In this study,we test the impact of ERP ( Enterprise Resource Planning) system implementation on earnings quality based on ERP adopters listed in Shanghai and Shenzhen stock market. Due to ERP adopters' lower managerial ownership,high shareholding concentration and weak checks and balances, we propose that managers have strong incentive to manage earnings. As advanced information technology,ERP systems provide users greater convenience to manage earnings; hence they may reduce earnings quality via enhancing earnings management. This hypothesis is supported by our empirical results. Our study differs from prior research in two ways. First,we develop our hypothesis taking into consideration of the incentive of ERP system's main user. Second,we adopt earnings quality proxies reflecting both base accounting and market related index. Our results suggest that managers et al. should concern the impact of user's incentive while evaluating the effect of ERP systems.
