文摘This paper aim to test two hypothesis about evolutionary path of industrial profit rate in Chinese industry.At first,we study the difference of industry profit rate,which indicate significant discrepancy among industries and industry level could explain a mass of differences,also significant time effect are reported.And then,we use AR(1)model and regress model test the evolutionary path and profit persistence,which report in china most industries obey time detrending mode and few follow stationary process.The conclusion give explain about these results and advice about future research.
