Procurement is an activity for enterprises to obtain materials, equipment and services for business activities, an important means for enterprises to obtain external resources, and plays an important role in the market competitiveness and status of enterprises and their survival and development. Effective management of enterprise procurement interaction is one of the important ways to improve enterprise competitiveness. ? Keywords: procurement; Supply chain; Supervision? 1 What does enterprise procurement management mean? Purchasing is an economic behavior in which economic subjects exchange goods or services for suppliers by paying a certain price in order to meet their own needs and get the maximum income with the least expenditure. The procurement process is a process of putting forward procurement requirements, selecting suppliers, negotiating prices, determining delivery and related conditions, signing contracts, and receiving and paying as required. Enterprise procurement management is all the management activities taken by enterprises to purchase the necessary quantity of goods or services from the appropriate suppliers at the appropriate price under the condition of ensuring the appropriate quality in order to realize the production or sales plan. The overall goal of procurement is that the materials it obtains should be genuine (that is, meet the quality requirements), the quantity should meet the requirements, and the materials should be sent to the right place at the right time. The materials must come from a suitable supplier (that is, a reliable supplier who will fulfill the promised obligations in time). At the same time, you need to get the right service (not only before buying, but also after trading), and of course the price must be reasonable. ? 2. Countermeasures to strengthen enterprise procurement management? 2. 1 Strengthen training to improve the professional ability of purchasing personnel? Purchasing is not only a simple shopping behavior, but also a professional technology. The purchasing staff of foreign companies are often engineers, because purchasing requires professional knowledge. Purchasing personnel should be familiar with the business and have the professional quality to meet the post requirements. Specifically, it includes: mastering the procedures and methods of business contract negotiation and signing; Master the enterprise procurement policies and written procedures related to procurement and procurement quality control, and can conscientiously implement them in the work; Understand the needs of customers and suppliers, and be proficient in using information technology such as computers; Have the mind to consider the comprehensive cost and fully understand the requirements of the overall supply chain; Have solid professional technical knowledge, technical and quality expertise related to purchased goods, including physical and chemical characteristics, standards and methods for inspection and judgment of quality, etc. ? 2.2 motivate purchasing personnel? The direct purpose of incentive mechanism is to mobilize the enthusiasm of procurement personnel and seek the consistency of organizational interests and personal interests. Mainly: (1) threat incentive. Threat incentive is suitable for economic depression, recession or enterprises facing difficulties in development. At this time, the market share of enterprises decreases, and they are in danger of bankruptcy or merger and reorganization. In order to tide over the difficulties, enterprises need to lay off employees or reduce jobs, so employees are facing the danger of unemployment and the pressure of competition. At this time, we can use threat incentives to urge employees to work harder, strive for jobs and salaries, and avoid being laid off or demoted. (2) Incentive mechanism. Incentive refers to the use of bonuses, red envelopes, overtime and other economic means to encourage procurement personnel to work hard and improve their work performance, so that enterprises can improve procurement efficiency and obtain more profits. (3) Work enrichment and motivation. This refers to providing employees with more development opportunities, enriching their work content and increasing their work responsibilities. It can take the form of providing procurement personnel with opportunities to participate in enterprise management and decision-making, more training opportunities and opportunities to realize themselves. These three incentive methods basically cover the incentive forms of enterprises to purchasing personnel, and each has its own advantages and disadvantages. Enterprises should treat reconciliation and use differently according to specific conditions. ? 2.3 Encourage suppliers? Purchasing is an external purchasing behavior of enterprises to meet specific needs. In this behavior, the interest relationship between suppliers and customers is not completely consistent. It is necessary to accurately define the interests of enterprises in the ever-changing purchasing interests, and conduct purchasing behavior on this basis. The incentive for suppliers is: (1) price incentive. Price has obvious incentive effect on suppliers: high price can enhance the enthusiasm of enterprises, while unreasonable land price will dampen the enthusiasm of enterprises. In order to motivate suppliers and improve procurement efficiency, suppliers should be given certain price concessions and discounts to ensure stable cooperation and smooth operation between supply enterprises and procurement enterprises. (2) Order incentives. For suppliers, getting more orders is a great incentive. Generally speaking, a manufacturer has multiple suppliers, and the competition among these suppliers comes from the manufacturer's orders. Giving more orders can motivate suppliers and promote their behavior rationalization. (3) Credit incentives. Credit is an intangible asset of an enterprise, which reflects its social status (including economic status, political status and cultural status). Credit is one of the main factors that affect the business income of suppliers. Therefore, enterprises, as purchasers, should work hard on the issue of reputation and improve their reputation through voluntary publicity of suppliers, so as to achieve the purpose of encouraging suppliers. (4) Relationship or level incentives. Enterprises should evaluate suppliers according to trading experience, classify suppliers into different grades according to standards such as price, quality, delivery date and credit, and establish long-term cooperative relations with suppliers with good conditions in all aspects. (5) participate in manufacturing. Combine suppliers, distributors and even users into product research and development, cooperate in all directions according to the interests of the team, form an incentive mechanism, and make suppliers' behavior positive. 2.4 Restrict purchasing power? Many enterprises in our country have the phenomenon of centralized power in the procurement process. The purchasing power is concentrated in the hands of a few leaders, the purchasing management department exists in name only, and the purchasing activities are out of control. Performance: unplanned procurement, blind procurement, disorderly procurement; Procurement demonstration and evaluation are not in place, lack of market research and analysis, and capital and production are damaged; Procurement is not open to public bidding, or the bidding is not standardized; When signing a contract, they don't seriously implement the contract law, and some don't even sign a house purchase contract, and they don't care about the implementation of the contract afterwards. Some reimbursement amounts are much higher than the market price or contract price at that time, resulting in losses and waste; Inconsistent purchase acceptance and inconsistent accounts and materials lead to economic disputes and economic losses to enterprises. The procurement department should establish a standardized internal management system, define the job responsibilities of each post according to the nature and tasks of procurement, determine the rights and obligations of procurement personnel, and try its best to formulate a democratic and controllable procurement operation mechanism. First of all, effectively control the purchasing decision-making power, establish an internal power balance mechanism with controlled power, and control major purchases. Collective democratic decision-making activities. Secondly, effectively control the purchasing management right, and separate the authority subjects of purchasing management right such as purchasing plan right, bidding inquiry right, market purchasing right and acceptance settlement right. The right of purchasing plan is in the hands of the purchasing unit, and the purchasing management department is responsible for the examination and approval of the purchasing plan. The right of bidding and inquiry is in the hands of the purchasing unit and the finance department. The responsibilities of each link are clear, non-interference and checks and balances. Only by decentralizing and controlling the excessively centralized procurement power can we effectively curb procurement corruption. ? 2.5 Supervise and constrain procurement? Supervision and restraint include two aspects: the supervision of managers on purchasers and the mutual supervision between purchasers. The procurement link should form a supervision and guarantee mechanism based on prevention and appropriate constraints. The first is to establish a responsibility system for rewards and punishments for clean procurement. Clear responsibilities, strict assessment, enhance the management awareness and clean government awareness of procurement personnel, and give certain material and spiritual encouragement to procurement personnel who strictly abide by the procurement management system, save more and have the highest procurement quality; Those who neglect their duties or have dishonest behavior in purchasing decision-making will be held accountable. Encourage saving procurement costs, improve procurement quality, and implement clean procurement. Second, adhere to the combination of supervision by supervision departments and supervision by the masses to make supervision open, regular and institutionalized. By establishing a system, we can monitor the procurement efficiency of enterprises, let the supervision department participate in the procurement activities throughout the process, strengthen the supervision before personnel, and prevent problems before they happen. By mobilizing the masses to participate in supervision, we can invite the invited inspectors from the masses and the market to conduct public democratic appraisal and supervision and report on the procurement behavior of enterprises, deal with buyers and suppliers who fail to pass the democratic appraisal, and find out violations of discipline and law. ? 3 conclusion? With the development and perfection of market economy, procurement has developed from a simple commercial transaction to a function and specialty. In modern enterprise management, procurement is becoming more and more important. The success of outsourcing parts and raw materials procurement greatly affects the competitiveness of enterprises. Therefore, getting out of the misunderstanding of traditional procurement and correctly understanding the importance, operation mode and method of procurement and procurement management are the basic guarantee for today's enterprises to survive in the competition of globalization and information market economy, and also the inevitable requirement for modern enterprises to seek development and growth. ?
