Abstract: The two important hypotheses-state-owned enterprises bear low efficiency,and the governments have a soft budget constraint to them-from which professor LIU Rui-ming and SHI Lei draw the conclusion that double efficiency loss exists with state-owned enterprises,are not in accordance with actuality.Through an empirical analysis with the 29 provincial panel data from 2000—2008,it can be seen that the state-owned enterprises have significant positive effects,rather than an increase drag,on economic growth.Therefore in view of research methodology,conclusions of previous research can not be taken as the premise of present research without careful evaluation.With the relations between state-owned and private economy,it is not appropriate to one-sidedly emphasize the withdraw of state-owned economy from competition,or simply oppose state-owned economy with the the private economy.

Key words: state-owned enterprises’ efficiency, soft budget constraint, growth effects, the state enterprises’ reform
