E-Stats

The e-commerce measures report the value of goods and services sold online whether over open networks such as the Internet, or over proprietary networks running systems such as Electronic Data Interchange (EDI). E-commerce data were collected in four separate Census Bureau surveys. These surveys used different measures of economic activity such as shipments for manufacturing, sales for wholesale and retail trade, and revenues for service industries. Consequently, measures of total economic and e-commerce activity vary by economic sector, are conceptually and definitionally different, and therefore, are not additive.本报告中的电子商务统计指标涵盖通过互联网等开放网络，或是搭载电子数据交换（Electronic Data Interchange, EDI）系统的专有网络完成的在线商品与服务销售价值。电商相关数据由美国人口普查局通过四项独立调查采集。上述四项调查针对不同经济活动类型采用了差异化的统计口径：制造业以发货额为统计标准，批发与零售业以销售额为统计标准，服务业则以营业收入为统计标准。因此，总经济活动与电商活动的统计指标因经济门类而异，无论在概念层面还是定义层面均存在差异，故不可直接累加。
