跨国公司对我国电信设备制造业技术创新能力的影响——一个实证研究

20世纪90年代以来,拥有强大技术优势的跨国公司大量进入中国电信设备市场,给幼小的中国电信设备制造企业带来了巨大的技术冲击和市场竞争压力。为了适应激烈的国际竞争,以华为、中兴为代表的我国电信设备制造企业以技术创新为突破口,逐渐建立起具有自主知识产权的核心技术体系,实现了企业的快速成长。本文采用实证研究的方法,检验跨国公司进入与我国电信设备制造业技术创新能力之间的关系,结果发现,跨国公司对我国电信设备制造业技术创新能力具有直接的促进作用;通过对其作用机理的分析,发现跨国公司主要是通过四种效应促进了我国电信设备制造业的技术创新:即生产效应、竞争与学习效应、市场效应和内部研发效应。

An integrated indicator system for patent portfolios: evidence from the telecommunication manufacturing industry

Against the background of ‘patent portfolio races’ in industries such as telecommunications, this paper proposes a set of patent portfolio indicators to measure patents’ scale and diversity. This indicator system is used in a time series to analyse the patenting activity and technology strategy of the world’s top 20 firms in the telecommunication manufacturing industry, based on a large data set from United States Patent and Trade Office. In combination with composite and relative measures, we identify the firms’ comparative positions in patenting activity. The paper adds to the ongoing discussion about, and enriches the theory of, patent portfolios.     

我国电信产业中的垄断经营和政府管制分析

许多经济学家认为,产业壁垒形成的主要原因是规模经济,沉没成本,差别化经营等。对中国电信产业分析得出的基本结论是：中国电信的主要产业壁垒不是来自市场,而是来自不合理的政府管制,政府管制使得电信价格在电信成本不断下降的情况下仍然保持刚性。分析中国电信垄断经营和政府管制的市场绩效,探讨了不合理管制背后的原因,提出一些促进电信改革,矫正政府管制行为的实现建议。     

Network effects in mobile telecommunications markets: A comparative analysis of consumers' preferences in five Latin American countries

It has been shown that the presence of demand-side externalities can induce the market to benefit the largest firms in terms of market share, usually named as network effect by the theoretical literature. On the one hand, macro-level approach in the empirical literature of network effects commonly use the assumption that a network's overall size matters more to consumers' decisions (global network effects). On the other hand, micro-level studies have suggested that social networks are more relevant to consumers' choices than the overall network size (local network effects). Based on microdata from five Latin American countries, we compare the choice of a particular operator over choosing the largest operator by individual consumers. Our research shows that country-level network size is one among a set factors that determine consumers' choices of mobile operators, once individual and operators' country presence heterogeneity are considered. We find that consumers' local network decisions are important for the choice of operator in the majority of cases considered, and that this result is conditional on the chosen operator's market share. Furthermore, network characteristics and consumer preferences, such as coverage, tariffs, and network importance also affect the choice of mobile network for the Latin American context.
