Taking all the Chinese A-share listed firms that disclosed R&D spending from the year 2008 to 2011 as the whole sample, the empirical analyses of their 794 annual data showed that:in the first year after CEO turnover, the firm′s R&D spending has a significant increase. The results of sub-sample tests also showed that:when the top managers are overconfident or if the firm belongs to high-tech industry, the positive correlation between the new CEO and the R&D spending is much stronger %K CEO变更 %K 研发投入 %K 盈余管理< %K br> %K CEO turnover %K R& %K D spending %K earnings management %U http://skxb.xjtu.edu.cn/oa/DArticle.aspx?type=view&id=201502004
