With the co-integration analysis on time series data,it can be found that there were a long-term dynamic equilibrium telation and a short-term error correction mechanism among economic development,system transferring and administration cost in 1978~2003 in China.The economic development had a promoting influence to the administration cost,and the system transfering had a negative effect to the administration cost.With the method of pulse response function and the variance decomposition based on VAR model,it can be discovered that the administration cost had a bigger response to the change rate of economic development than to that of system transferring.
