摘　　要：在企业与上下游合作关系日趋紧密的背景下,企业对主要商业伙伴的依赖程度显著影响其财务管理行为。文章从议价能力视角出发,以2012-2020年沪深A股上市制造业企业的经验数据为观测对象,实证检验企业供应商集中度对于盈余管理行为的潜在影响及其作用机制。研究结果表明:供应商集中度与企业盈余管理显著正相关,即供应商集中度越高,盈余管理行为越频繁;商业信用融资是供应商集中度与盈余管理间正向关系的中介变量,表明供应商集中度通过降低商业信用融资规模、缩减商业信用融资周期促使企业进行更多的盈余管理活动。文章在理论层面丰富了供应商集中度作用效果和盈余管理影响因素的研究视角,在实践层面为企业改善会计信息质量、完善公司内部治理提供了行之有效的政策建议,同时为监管者推动市场有序发展拓展了新思路。Due to the increasingly close relationship between firms and their upstream and downstream partners,firms’dependence on major partners significantly affects their financial management.Therefore,from the perspective of bargaining power,this study empirically examines the potential impacts of firms’supplier concentration on the earnings management behavior and the mediating effects of commercial credit using the data of A-share listed manufacturingfirms in Shanghai and Shenzhen from 2012 to 2019.The results show a significant positive impact of supplier concentration on earnings management.The higher the supplier concentration,the more frequent the earnings management behavior.Furthermore,commercial credit mediates the positive impact of supplier concentration on earnings management,which indicates that supplier concentration increases earnings management activities by reducing commercial credit scales and shortening commercial credit cycles.This studycontributes to the theory of supply chain management and earnings management by introducing supplier concentration as an important factor.The findings provide effective managerial implications tohelp managers to improve the quality of accounting information and the internal governance.Moreover,the findings also give the guidance to the policy-makers of the securities market.
