The Administrative Procedure Law and Basic Administrative code should be integrated which include the Due process. The procedural part of the basic administrative code should absorb local administrative procedure legislation experience fully. From the legislation content，openness is the foundation，participation is the essence，fairness and efficiency are the cores. the system generally applicable to administrative acts should be incorporated，not too much. From the legislative structure，order and behavior can be clues. it can be composed of administrative act procedure，administrative law enforcement procedure，special procedure and so on，according to the process of starting，proceeding and ending. Rules of due procedure are to establish a unified lowest standard；Other regulations should not go beyond the bottom line.
