互联网给我们的工作和生活带来的,绝不只是一个“第四媒体”或者路边竖着的“网聚人的力量”之类的广告牌。互联网的真正力量,在于它带来的新模式深深地渗入并改变了传统的东西。传统的政治经济学教科书说,人们在生产劳动中结成的关系称为生产关系,互联网在改变人与人之间的联系的同时也就更新了生产关系。科斯的交易成本理论告诉我们,在市场经济中,作为各个部门组合的公司之所以能够存在,是因为市场交易存在成本。当与前一道工序的部门协同工作的效率比到市场上购买更高时,作为公司运作就更有利。同样,如果新增一个部门的成本比到市场上买更合算,相应的市场就会趋于消失。对于不同规模、不同行业的企业来说,做同一件事的成本往往是不一样的,这就促进了市场的细分。互联网对交易成本的降低是随处可见的,当达到一定程度 What the internet brings to our work and life is by no means just a billboard like a “fourth media” or a “net-gathering force” standing on the side of a road. The real power of the Internet is that the new paradigm it brings deeply penetrates and changes the traditional. The traditional textbook of political economics says that the relations people forms in productive labor are called production relations and that the Internet renews the relations of production while changing the connection between people. Coase’s transaction cost theory tells us that in a market economy, the existence of a company as a portfolio of various sectors exists because of the costs of market transactions. It is more advantageous as a company to operate when working in synergies with the departments of the previous process than it is to buy in the market. Similarly, if the cost of adding a department is more cost-effective than buying on the market, the corresponding market tends to disappear. For enterprises of different sizes and industries, the cost of doing the same thing is often different, which promotes the market segmentation. The reduction of transaction costs on the Internet is ubiquitous when it reaches a certain level
