“脱媒”假说

在电子商务的早期的讨论中，我们可以发现假设“脱媒”信息和通信技术的传播，特别是互联网，可以减少必要的时间和费用，以收集有关交易的信息。因此，生产者和消费者应该能够更好地处理直接。结果，商人的中介功能，如批发商和零售商，将变得越来越不必要。

The Power of the Middleman in Electronic Markets

– The Case of the German Bookselling Industry

The paper focuses on the hypothesis of “disintermediation”, that establishes a diminishing role for traders, or intermediaries respectively, with the arrival of electronic commerce, because producers and consumers may transact online in a direct way. However, the analysis of the German bookselling industry, which has a relatively well-established branch of b2c electronic commerce, presents an ambiguous picture of disintermediation. Structural changes which are not only caused by technological development, result in a wide range of types of traditional and new online intermediaries which fulfil specific combinations of intermediary functions.

The “Disintermediation” Hypothesis

In the early discussion of electronic commerce, we can find the hypothesis of “disintermediation” (e.g. Benjamin, Wigand 1995). The spread of information and communication technologies (ICT), in particular the Internet, allows the reduction of necessary time and costs for gathering the information that is relevant for trading transactions. Therefore, producers and consumers should be able to better transact directly. As a result, the intermediary functions of traders, e.g. wholesalers and retailers, would become more and more unnecessary.
