我们提供的证据表明，将资产回报率分解为资产周转率和利润率并不能提供用于

We provide evidence shows that return on assets will be broken down into asset turnover and profit margins do not provide incremental information for predicting a year of change in return on assets, return on assets but may be classified as asset turnover and change changes in asset-liability ratio. Changes in the coming year profit return on assets can be used to predict

The evidence we provide is that breaking down return on assets into asset turnover and profit margins does not provide incremental information to predict changes in return on assets a year ago, but rather categorizes return on assets into changes in asset turnover and changes in asset-liability ratios. Profit margin can be used to predict changes in return on assets for the coming year

The evidence we provide shows that the decomposition of asset return into asset turnover rate and profit rate can not provide incremental information for predicting the change of asset return one year ago, but can be classified into asset turnover rate change and asset liability rate change. Profit margin can be used to predict the change of return on assets in the next year<br>
