The Assessment: Economics of the Internet
从经济学视角审视互联网对生产率的影响,发现效果有限且主要集中在美国;同时指出互联网并非天然高度竞争,规模经济和广告密集型声誉可能导致集中,因此需要促进竞争的政策,并考虑市场失灵和民主权利保护。
Seen from the perspective of economics, the Internet has been widely regarded as a major force likely to raise productivity. However, at least so far, the identifiable effects on productivity appear small and largely confined to the USA. Similar scepticism is expressed about the view that the Internet would be naturally highly competitive. On the contrary, economies of scale and scope plus advertising-intensive reputations create the threat of concentration. As a result, a pro-competitive stance for policy is required--and in taking such a stance policy must look over the full range of the value chain. Such a pro-competitive stance is, however, not sufficient. Because of other market failures and because of the need to protect democratic rights, a wider view of policy is essential. The fundamental policy issues facing the Internet are, therefore, whether it can remain open, competitive, and pluralistic in a context increasingly dominated by large corporations.
