上市公司投资质量的测度指标包括投资规模（选用回归方程的残差指标）与投资结构（选用多元化指数DT指标）两部分指标。使用2007年至2009年我国上市公司数据进行实证检验,发现该指标体系具有科学性。运用加权平均法对2009年我国上市公司投资质量进行综合的计分与排名,进一步验证了该指标体系具有可行性。

The measurement indicator of the invest quality of listed firms should include investment size（adopt the residuals of regression equation） and investment structure（adopt DT which reflects the diversification degree of enterprises＇ operation）.Through the empirical tests with the actual data of Chinese listed firms from 2007 to 2009,we found that the indicator system might be scientific.Based on the above statistical analysis,we adopted the weighted average method to score the invest quality of Chinese listed firms in 2009 and rank them one by one,and further validated the feasibility of our indicator system.
