由于销售额强劲增长，2007年全球最大的20家电子合同制造商继续扩大其占全球市场销售额的份额。但iSuppli公司认为，这个简单的事实掩盖了影响该产业竞争动态的一些比较复杂的现实。

10大EMS提供商2007年占全球EMS营业收入的71.8%，高于2006年时的70.4%。同时，2007年 10大ODM厂商占全球营业收入的比例从2006年的75.2%上升到83.8%。

细节决定成败

EMS: the abbreviation of electronic manufacturing services, that is, electronic manufacturing services. Electronic professional manufacturing services is also known as ECM (electronic contract manufacturing). It is also translated into professional electronic OEM services in Chinese. It is an emerging industry. It refers to manufacturers that provide a series of services such as manufacturing, procurement, partial design and logistics for brand owners of electronic products.

ODM is the abbreviation of English original design manufacturer, and its literal translation is "original design manufacturer". ODM means that after a manufacturer designs a product, it may be favored by other enterprises in some cases, requiring the latter's brand name for production, or slightly modifying the design for production. Among them, the manufacturer undertaking design and manufacturing business is called ODM manufacturer, and its products are ODM products.

Due to the strong growth of sales, the world's 20 largest electronic contract manufacturers continued to expand their share of global market sales in 2007. However, iSuppli believes that this simple fact masks some complex realities affecting the competitive dynamics of the industry.
