摘要:本文调查了市场结构对互联网经济的创新产生了哪些有利的影响，并探讨了垄断市场的创新利益是否明显不同于竞争性市场，在哪些方面有所不同的问题？

本文主要根据Schumpeter和Arrow的理论论证创新的激励因素，侧重于竞争产生的垄断市场结构的研究，以及在竞争性垄断市场结构而不是完全竞争市场结构中创新的优势，并分析研究不同的现有企业案例从中得出结论。更具体地说，我调查了创新的决定性因素和创新与市场结构的桥梁。

根据相关文献和互联网行业案例，本文观察到竞争使互联网市场已经产生垄断现象。公司必须发展许多创新产品，以保持垄断者地位，由于创新需要大量的资金支持和强大的人力资源，而垄断者由于拥有垄断地位意味着掌握一定的市场势力可以控制相关产品的价格。相比之下，竞争市场中那些没有市场势力的公司无法获得足够利润，因为他们的产品价格接近于边际成本，使他们没有足够的资金投资于创新研究。68801

Which market structure is the most favorable to innovation in the Internet economy?

Abstract:This paper has investigated how the market structure has a impact on the innovation in the Internet economy and examines whether the benefit to innovate in monopoly market is obviously different from the competitive market? 

The current paper has analyzed the simulation in innovation mostly from Schumpeter's theories and Arrow's point, focusing on competition study that generated monopoly market structure and the advantage of innovation in competitive monopoly rather than in competition structure, and drew conclusions from the different existing enterprise cases. More specifically, I have investigated the determining factors of innovation and the way they are related to the market structure.

According to relevant literature and the Internet industry cases, observing competition the Internet market have generated monopolist. The company has to develop many innovations to keep the monopoly position, because the innovation is in need of abundant funds and strong human resources, it is easy to make that monopolist due to monopoly has market power to control the price. By contrast, the companies in competition market have no market power thus their product's price was closed to marginal cost leaving them without enough funds to invest in innovation.
