Research On Internal Control Optimization Of Sales And Collection Business Of A Pharmaceutical Company Based On Blockchain Technology

In recent years,the emergence of new science and technology such as big data,cloud computing and blockchain has brought disruptive changes to various fields and promoted industrial transformation.in March 2021,the 14 th Five-Year Plan and the outline of the 2035 Vision proposed to cultivate and grow new digital industries such as artificial intelligence,big data and blockchain.At present,blockchain technology has been widely used in finance,accounting and supply chain,but there is less research and application in internal control.The pharmaceutical industry,as a provider of pharmaceuticals,a special product,is related to national health and life safety,and bears an important social responsibility.However,the fraudulent incidents of Kangmei Pharmaceuticals and Changsheng Biologicals in recent years have repeatedly aroused the concern of the community about the internal control of pharmaceutical companies.The sales and collection business determines the business status and development prospect of an enterprise,and the importance of its internal control cannot be overstated.Moreover,the complexity and complexity of the sales business of pharmaceutical enterprises and the flexibility of sales personnel have greatly increased the difficulty of implementing internal control of sales and collection business.The characteristics of blockchain technology,such as immutability,traceability and openness and transparency,can,to a certain extent,provide comprehensive and real-time supervision of the sales and collection business activities of pharmaceutical enterprises,greatly improve the quality of accounting information and enhance the effectiveness of internal control.Using the methods of literature analysis and case study analysis,this paper summarises the current research status of internal control and blockchain technology application at home and abroad,and conducts a case study of pharmaceutical company A in conjunction with the current core technology and features of blockchain.Firstly,the development characteristics of the pharmaceutical industry and the basic situation of pharmaceutical company A are introduced,followed by an analysis of the current status of internal control of pharmaceutical company A’s sales and collection business according to the five elements of internal control,and a A detailed analysis revealed that there were problems such as ineffective management of customer credit,improper management of sales contracts,opaque information on drug distribution,poor management of accounts receivable and poor information communication.Secondly,based on the analysis of the causes of the problems in the internal control of sales and collection business of pharmaceutical company A,and combined with the functional characteristics of blockchain technology such as decentralisation,consensus mechanism,smart contract and traceability,the overall architecture of internal control of sales and collection business based on blockchain technology was designed,and specific optimisation measures were proposed: consensus mechanism to confirm the credit level of the enterprise,ensure the authenticity of the sales contract signed,drug The blockchain technology is also used to ensure the authenticity of sales contracts,drug traceability,cryptographic algorithms to ensure the security of fund payments,and to facilitate information communication and internal and external supervision.Then,in order to ensure that the internal control optimisation solution with blockchain technology can achieve the expected results in Pharmaceutical Company A,safeguards are proposed in four aspects: system,data,human resources and technology.Finally,the expected results of this optimisation solution are analysed from three perspectives,including the quality of accounting information,company operating costs and company supervision and management.This paper finds that the use of the core technology and features of blockchain can effectively improve the quality of internal control and strengthen the supervision and management of the entire sales and collection business of the company.On the one hand,this study provides reference suggestions for other enterprises in the same industry to build internal control of sales and collection business,and on the other hand,it provides new ideas for the integration of blockchain technology and enterprise internal control.
