【摘要】 本文基于软件市场规模经济和网络外部性的特点,构建了扩展的单寡头垄断模型、伯川德模型和豪泰林模型将软件市场区分成四种典型的市场结构,进而研究了软件市场结构和软件保护不同方式的作用机理。研究表明,在软件的规模经济特性、网络外部性及IP法律保护等因素的影响下,在市场结构不同的软件市场,软件厂商强化传统价格和产品差异化等竞争手段的同时,会选择不同的最优源码保护程度展开市场竞争,从而导致不同的创新成本和软件质量,并且市场结构的不同也影响了最优的IP法律保护程度。更多还原

【Abstract】 In this article,combining with scale economy and network externalities of software markets,and considering the four kinds of typical market structure of software industry,authors expand traditional monopoly-model,bertrand-model and hotelling-models to study the functionary mechanism of software market structure and software protection.It is indicated by the research that under the influence of the factors such as scale economy,the network externalities and the IP law protection etc,software firms in different markets not only enhance traditional competitive means,for example,price competition, product differentiated competition etc,but also adopt different levels of source-code protection to reduce the innovative cost and raise the product quality,at the same time the Optimal IP Law Protection changes.更多还原
