Electronic commerce, or e-commerce, is simply business that is conducted over the Internet. Government e-commerce applications are those e-commerce applications utilized by some level of government, whether it is federal, state, or local. In this article, we will distinguish between interactive transactions and e-commerce transactions. Strictly speaking, e-commerce applications are only those in which a financial transaction of some sort takes place. Interactive transactions would involve interaction with a Web survey or some other application like filing an online form requesting services or submitting a complaint, but financial transactions are not included. Electronic commerce applications are an important segment of the growing e-government service delivery field. Government e-commerce applications may involve G2B (government-to-business), G2G (government-to-government), or G2C (government-to-consumer or, in this case, citizen) mechanisms. Table 1 provides examples to illustrate the differences between e-government activities like information provision, non-e-commerce interactive transactions, and e-commerce transactions.
