摘要：1 Trend toward networking in
transactions
Transactions on the network (online transactions, “ecommerce”)
are expected to help improve market efficiency.
For example, in an e-commerce market, companies
can participate in the market regardless of the number
or size of their stores. Consumers can also gather
product information and compare prices without geographic
restrictions; this reduces uncertainty due to the
information mismatch and enables needs-based diverse
transactions.
