随着我国证券市场的迅猛发展,信息使用者愈发关注上市公司的收益质量,对企业收益质量进行分析与评价以更好地把握上市公司的发展趋势显得尤为重要。而上市公司经营效益直接影响到企业的整体竞争力和核心服务质量。以苏锡常地区先进制造业上市公司的收益质量问题为研究对象,理论为辅,实证为主,结合先进制造业特点,构建一个新的收益质量评价体系,先根据因子分析得到的综合得分对各上市公司的收益质量进行评价并检验其有效性,再采用描述性统计分析、相关性分析和回归分析等方法对上市公司的经营效益与收益质量的相关性进行研究,最后验证了企业经营效益与收益质量正相关这一假设,以助于政府、投资者等利益相关者更好地了解企业的运营情况。

With the rapid development of China＇ s securities market, information users are increasingly concerned about earnings quality of listed companies, which is very important for them to analyze and evaluate their earnings quality to grasp the development trend of listed companies better. The operating efficiency of listed companies has a direct impact on the overall competitiveness of enterprises and the quality of core services. A new income quality evaluation system is constructed empirical- ly and theoretically both by setting Suzhou, Wuxi and Changzhou area as the samples. Firstly, according to the comprehensive score obtained by factor analysis, we evaluate the earnings quality of listed companies and test their effectiveness. Secondly, we use the descriptive statistical analysis, correlation analysis and regression analysis and other methods to study the correlation between the operation efficiency and the earnings quality of listed companies. Finally, the hypothesis that the operation efficien- cy is positively related to the earnings quality is verified, that is helpful for the government, investors and other stakeholders to better understand the operation of enterprises.
