供应商的实力是一个买方势力的镜像。因此,分析供应商的实力通常首先关注供应商的相对大小和浓度相对于行业参与者和第二输入提供差异化的程度。客户收取不同价格的能力与创造的价值差异对每个买家通常表明市场的特点是高供应商的实力,同时低买方势力(波特,1998)。供应商讨价还价的能力存在于下列情形。
一个行业的竞争的本质是强烈建议五种力量影响。买家和供应商的力量越强,进入和替代的威胁越强,越激烈的竞争可能会在这个行业。然而,这五个因素并不是唯一,确定公司的行业竞争,行业本身的结构可能会发挥重要作用。事实上,整个五种力量框架是基于一个经济理论知道的“Structure-Conduct-Performance"(SCP)模型:一个行业的结构决定了组织的竞争行为(行为),进而决定了他们的盈利能力(性能)。在行业集中,根据这一模型,组织将更少的激烈竞争,获得更高的利润,比在支离破碎的。然而,Haberberg Rieple(2001)状态,业内企业的历史和文化也发挥了非常重要的作用在塑造竞争行为,和SCP模型的预测需要相应地修改。

Supplier power is a mirror image of the buyer power. As a result, the analysis of supplier power typically focuses first on the relative size and concentration of suppliers relative to industry participants and second on the degree of differentiation in the inputs supplied. The ability to charge customers different prices in line with differences in the value created for each of those buyers usually indicates that the market is characterized by high supplier power and at the same time by low buyer power (Porter, 1998). Bargaining power of suppliers exists in the following situations.
The nature of competition in an industry is strongly affected by suggested five forces. The stronger the power of buyers and suppliers, and the stronger the threats of entry and substitution, the more intense competition is likely to be within the industry. However, these five factors are not the only ones that determine how firms in an industry will compete - the structure of the industry itself may play an important role. Indeed, the whole five-forces framework is based on an economic theory know as the "Structure-Conduct-Performance" (SCP) model: the structure of an industry determines organizations' competitive behaviour (conduct), which in turn determines their profitability (performance). In concentrated industries, according to this model, organizations would be expected to compete less fiercely, and make higher profits, than in fragmented ones. However, as Haberberg and Rieple (2001) state, the histories and cultures of the firms in the industry also play a very important role in shaping competitive behaviour, and the predictions of the SCP model need to be modified accordingly.
