Competition in Telecommunications Industry: Impact of Liberalization and Innovations

论文摘要

在理论中,竞争的好处是显而易见的。垄断,不管是私有的还是公有的,都是无效率的,是对社会是有害的。垄断不仅带来高价位和少数消费者,而且还带来了对于运营者的低效运营。竞争的自然选择性会选择一些市场上的高效率公司,而这种现象会打破政府干扰市场。竞争的好处使得放松管制和自由化开始存在于原本被认为垄断是高效的电信市场,而这种认知是因为沉积成本和持续的经济范围性和规模性而存在的。服务和技术中的快速创新腐蚀了电信市场的自然垄断性。很多国家的经验说明竞争在某些领域是可行的,例如:在长途,无线和增值领域。无线的技术创新使得无线代替了固定电话,还有一些新的技术来代替电缆技术等。光缆和电力线技术也已腐蚀了当地网络(最后一公里)的垄断性。这篇博士论文的主要目的就是重新研究在电信行业内新发展和创新带来的竞争好处和形势。之前关于竞争的研究都是从市场的角度研究竞争的影响。在本文中,用公司的价格成本函数研究了从公司的角度上竞争在社会福利上的影响。此外,本文还讨论了自由化可以为电信行业带来竞争和自由化对社会的影响,技术创新对竞争和市场结构的影响,和竞争、政策和管制的新趋势。本文大量运用图表/曲线去解释和探讨一些问题,还运用了博弈论理论,和巴基斯坦,韩国的案例分析来分析竞争的好处,研究了一些国家采用的新技术。竞争是对消费者和生产者都是有好处的,虽然可能对消费者好处会更多。在发达国家的趋势是放松管制:对竞争政策会更多依赖而不是对行业的特殊管制,还有对兼并会更加容忍,因为兼并对社会是有好处的。技术创新和融合使得在所有的电信分行业市场竞争升级。无线技术平台在发展中国家变成主导来提供电信服务。行业中的强烈竞争导致电信服务因为低廉的价格在某些国家迅速渗透。而这种现象使得整个国家的经济有了很好的提升。
