To analyze the interest distribution relationship and symbiotic mode in the construction of urban medi-cal groups,based on the symbiotic theory,a framework for analyzing the interest distribution relationship of urban medical groups is constructed.Based on actual cases,urban medical groups are summarized and divided into four types:one-way supply type,partial benefit symbiosis type,asymmetric reciprocity symbiosis type,and symmetric reciprocity symbiosis type.The focus of a one-way supply oriented urban medical group is on reshaping the profit distribution mechanism,a partial benefit symbiotic urban medical group is on establishing a profit compensation mechanism for benefit medical institutions,and an asymmetric and mutually beneficial symbiotic urban medical group is on building a long-term benefit balance mechanism.
