Research On The Excess Profit Tax Strategy For The Availability Of Patented Medicines Under The Game Of Government And Enterprise

Ensuring health and hygiene is the most basic and important requirement of mankind.Therefore,it is very important to formulate a patent drug system to protect technological inventions in the pharmaceutical industry.However,due to the strong protection of drug patents,the profit-seeking nature of pharmaceutical companies has been greatly strengthened,and the prices of the patent drug far exceeding the marginal production cost have been set,which has caused many patients to be unable to afford the cost of medication and get into trouble.Therefore,it is particularly important to balance the conflict between drug patent protection and the accessibility of patent drugs.Increasing the accessibility of patented drugs can make drugs available and affordable to patients,improve public health,effectively promote the redistribution of revenues between the government and enterprises,and ease the conflict between patients and pharmaceutical companies.As for the problem of low drug accessibility caused by with the help of Matlab mathematical software quantitative solution,the drug price control scheme proposed in this study,that is,the control effect of levying excess profit tax,is evaluated to impose an excess profit tax on expensive patent drugs to control drug prices based on literature research and improve the accessibility of drugs.Furthermore,China is a recognized generics country,as a latecomer,for a long time,the main body of the domestic pharmaceutical market is generic drug enterprises.However,the relative status of the original drug research enterprises,,pharmaceutical companies,and patients,and establish corresponding Mathematical model,discuss the impact of levy methods,levy objects,tax rates,etc.on the accessibility of drugs,and find ways to exchange the smallest innovation losses for the largest public health benefits.At the same time,it discusses the social medical insurance reimbursement policies and corporate competition in China's medical system.Firstly,based on the qualitative analysis of the excess profit tax,it is proposed to solve the optimal excess profit tax rate that the government should take,realize the control of the drug premium ratio,To provide policy reference for promoting the transformation and upgrading of generic drug enterprises in China.how to price drugs and how to How to make a corresponding production plan to maximize self-interest.First define the business amount function expression of the excess profit tax that should be levied by the enterprise.Alpine Bank focuses on the top-level design to promote the development of the pharmaceutical industry,a Stackelberg game model is established,and it is studied how the government passes the excess profit tax.,To regulate the price and production scale of a single type of drug in a company to achieve a win-win situation of patient satisfaction and tax revenue,and makes a comparative analysis of patent regulations,foreign investment control policies,price control system changes and improvement process.Through the KKT condition,the Stackelberg game model is transformed into a single-level optimization problem,and the PHR multiplier method is used to solve the optimal tax rate,the drug premium ratio and the production volume of the pharmaceutical company.The results show that under the coordination mechanism of excess profit tax,drug pricing can be effectively controlled and the availability of patented drugs can be improved.Secondly,the introduction of patented drugs is included in the real-world scenario of reimbursement of the medical insurance fixed ratio,while taking into account that pharmaceutical companies will choose to produce multiple drugs at the same time in order to improve their anti-risk capabilities.In this thesis,it is proposed to address the optimal drug premium ratio and the medical insurance reimbursement ratio of patented drugs that the government should set,and how pharmaceutical companies should price various types of drugs and formulate corresponding production plans under this tax burden and medical insurance policy.Maximize self-interest.Based on a Stackelberg game model with the government as the upper-level leader and monopoly companies as the lower-level followers,this paper studies how the government regulates the distribution of internal production resources through the use of excess profit tax and medical insurance policies,and sets the price and price of a variety of drugs.The scale of production is to achieve a win-win situation between patient satisfaction and tax revenue,and the problem of maximizing corporate revenue.Through the KKT conditions,the Stackelberg game model is transformed into a single-layer optimization problem,and the PHR multiplier method is used to solve the optimal tax rate,the reimbursement ratio of various patent drugs and medical insurance,the premium ratio of various drugs,and the production volume.The results show that under the synergistic mechanism of excess profit tax and medical insurance policies,companies have more room for profit,and can effectively control drug pricing and improve the availability of patented drugs.Furthermore,it analyzes the competition and benefit distribution between the original research drug companies and the generic drug companies in the pharmaceutical industry.On the basis of the Stackelberg game,it first introduces the multi-followers game,and explores the distribution of benefits between enterprises and generic drug enterprises in cross-licensing.Subsequently,this part of the research is based on the Stackelberg game model with the government as the upper-level leader and the multi-followers game of duopoly enterprises as the lower-level Stackelberg game model,restricting each other to formulate drug prices and production scales to achieve a win-win situation for patient satisfaction and tax revenue,and to maximize corporate revenue.Through KKT conditions,the Stackelberg game model is transformed into a single-level optimization problem,and the PHR multiplier method is used to solve the optimal tax rate,license fee percentage,drug premium ratio and production volume.The results show that under the synergistic mechanism of excess profit tax,competing companies have less room for profit due to the restriction of license fees,and there is a need to improve the control of patented drug pricing and the improvement of the availability of patented drugs.
