RESUMO
The expansion movement of the market and the reverse movement that it has encountered to control its expansion constituted the " double movement" written by the British scholar Karl Polan.In traditional China,because the market was strictly embedded in the social,political,economic and ethical structure,there was no so-called " double movement",and the trust between doctors and patients was naturally established and historical-ly continued.Since the reform and opening up,with the gradual introduction of market mechanism in the reform of medical system,the market was increasingly " un-embedded" and expanded rapidly.At the same time,the socie-ty represented by the patients and their families gradually began to wake up and took action against market expan-sion,forming a more typical trend of " double movement" and triggering a more obvious crisis of doctor-patient trust.From the perspective of "double movement",to rebuild doctor-patient trust in the new period must re-em-bed the market into the society and strictly regulate some spontaneous social reverse movements.
