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.     

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.

Service Quality Perceptions of Customers About Mobile Telecommunication Services: A Case of India

ABSTRACT

 Because of the intangible nature of services, there is always a challenge in front of service providers to find out which dimensions of service quality are more important for customers. The author presents the results of a study in India that assesses the service quality perceptions of customers about mobile telecommunication services. EFA explained 69.694% of variance and extracted eight service quality dimensions. The results of a multiple regression analysis show that customers attributed the highest importance to employee performance followed by transmission quality, competitiveness, support attributes, reliability, credibility, operational efficiency, and convenience. The sample consisted of 411 respondents.
