From the perspective of the new institutional economics, the institutional change of hospital accreditation & evaluation in China was summarized and the experiences of hospital accreditation & evaluation from international organizations and other countries were refined to put forward the counter-measures for institutional innovations of accreditation & evaluation in China.
