通过收集沪深两市66家上市公司2-12年期大约340个样本观察值数据,使用广义最小二乘法在我国背景下实证研究了ERP与公司盈利绩效的关系.得出了以下两个结论:采用ERP后,短期而言(ERP采用后第1-5年),我国上市公司的盈利绩效(以ROA、ROE衡量)在统计上显著降低了;采用ERP后,短期而言,我国上市公司的盈利绩效(以ROA、ROE衡量)在统计上显著降低了,而在一个较长时期内,随着时间的推移,这种负面影响逐年减少,具有边际收益递增效应,表现出U型关系;长期而言,ERP采用对盈利绩效具有统计上显著的正面影响.
By collecting the data of about 340 samples from 2 to 12 years in 66 listed companies in Shanghai and Shenzhen stock markets, we use the method of generalized least squares to study the relationship between ERP and corporate earnings performance under the background of our country, and draw the following two conclusions : After adopting ERP, in the short term (1 to 5 years after ERP adoption), the profit performance (measured by ROA and ROE) of listed companies in our country is statistically significantly lower; after using ERP, in the short term, the listed companies in our country The profitability (measured by ROA and ROE) decreased significantly statistically. However, over a long period of time, this negative influence decreased year by year with a marginal return increasing effect and showed a U-shaped relationship. In the long run, ERP adoption has a statistically significant positive effect on profitability performance.
