In this paper,the COLS technique is used to estimate the definite statistical boundary product faction of the society,the agriculture,the state\|owned enterprises and the rural enterprises.Then based on this,we get four series of their relative production efficacy.Through the statistical analysis to these series,we get some results,which indicate that:in general,we can consider that the money is really an important factor to effect the relative production efficiency;but the relative production efficiency don’t rises with the financial depth.
