选择多供应商采购的好处如下：

通过招标可在交货、质量和成本方面获得最大利益；
使采购具备透明度；
使采购行为具备一个基准；
可与全球行业趋势保持同步；

选择单一供应商并不意味着结成伙伴关系，如果选择的话，可能出于以下原因：

可以比多供应商投标方式获得更多利润
企业间针对特定市场结成联盟
可以获得70-80%的商业配额，还能辅以产量管理

Select multi-vendor procurement of the following benefits:

Can be delivered through public bidding, quality and cost to obtain maximum benefits;

Can be compared with multi-vendor bidding to get more profits
Inter-firm alliances for specific markets
Get 70-80% of commercial quota, but also supported by yield management
