Objective: By measuring of the possible maximum size of the personnel budget in public hospital, providing ideas and reference for the implementation of public hospital reform objectives, including gradually increasing the proportion of staff spending in business expenses. Method: Based on the data from Annual report of Henan provincial health finance in 2010-2016, this paper uses fuzzy linear programming method to construct the model of maximization hospital personnel expenditure budget, and using the model to measuring the better decision of personnel expenditure budget. Result: 1. Put forward reasonable feasible area of public hospital expenditure budget . 2. Constructing the model of the maximization of public hospital personnel budget, including linear programming, optimal scale and overall optimization models. 3. Taking all the hospitals in Henan provincial as a whole, trialing the possible largest budget for personnel expenditures may be 33 billion 376 million yuan, an increase of more than the actual size in 2016 of $829 million, accounted for 3.79 percentage point increase in business spending. Conclusion: By using the model, we can obtain the most feasible maximum scale of the public expenditure budget of the public hospital, which is based on the actual history of the hospital expenditure, reflects the development goal, and takes into account the reasonable expenditure structure.
