Objective:To study the willingness of county-level hospital physicians within a county medical alliance(alliance)to participate in county-township human resource integration for medical institutions, for furthering the development of such integration.Methods:Based on a discrete selection experiment, a questionnaire was designed for the selection of the work attributes that affect the participation of county-level hospital physicians in such an integration. On-the-job physicians from four county-level hospitals in a prefecture level city were selected by multi-stage stratified random sampling method as the survey objects, and a field questionnaire survey was conducted from November to December 2021. The mixed logit model was used to analyze the preference of physicians in county-level hospitals for five types of work attributes(work unit, monthly income, seniority required for professional title promotion, training opportunities, serving as middle-level and above administrators), the relative importance of each work attribute, and marginal willingness to pay with regard to their participation in the integration.Results:A total of 172 valid questionnaires were collected. When county-level hospital physicians participate in county-township human resource integration for medical institutions, their statistically significant job attributes and level preferences included monthly income, working unit of county-level hospitals, 7 years for professional title promotion, and more training opportunities ( P<0.001). The relative importance of monthly income ranked the highest among the five categories of work attributes, up to 55.55%. Conclusions:When physicians in county-level hospitals participate in the integration of county-township human resources, the most important was their monthly income, and economic incentives could enhance their willingness to participate.
