1. Timeliness and stability of supply: ensuring the supply of raw materials, spare parts, energy and machinery and equipment is the premise for the smooth marketing activities of enterprises.

2. Changes in supply prices: If suppliers raise the prices of raw materials, it will inevitably lead to an increase in the product costs of enterprises. If the product price is raised, it will affect the market price competitiveness and sales. If the price remains unchanged, it will reduce the profit of the enterprise.

3. Supply quality assurance: Whether the supplier can supply the production materials with guaranteed quality directly affects the product quality of the enterprise, and then affects the sales volume, profit and corporate reputation.
