网络融合下的中国电信业效率评价及其影响因素研究

本文从网络融合深化发展的现实背景出发,采用2003-2011年中国31个省市的平衡面板数据,在DEA-Tobit两阶段分析框架下研究了中国电信产业效率及其影响因素问题。研究结果表明：不同地区电信业的综合效率、纯技术效率差异较大,其中东部地区省份排名比较靠前;而规模效率普遍较高,且差异较小。在效率的影响因素方面,网络融合对我国电信业的综合效率和纯技术效率的提升均起到了积极的促进作用,价格规制政策、经济发展水平、人口密度、市场规模和电信业重要程度等宏观经济因素也从不同方面对我国电信业的效率产生了重要影响。     

Outsourcing and structural change. Application to a set of OECD countries

The examination in this paper aims to bridge outsourcing and structural change analyses in order to obtain more accurate insights into the extent of outsourcing and to extract more reliable policy recommendations for dealing with its effects. We do this by applying a ‘battery’ of outsourcing measurements to a group of OECD countries from 1980 to the mid 1990s. Expected results (e.g. the idiosyncratic outsourcing patterns of the UK) are confirmed on a more systematic and comparable basis, while original results (e.g. the low integration of business services in manufacturing in the former socialist economies) are based on the exploitation of new data.     

基于知识权力和知识交互行为的产业集群多重知识网络演化分析

针对产业集群知识网络中客观存在但却未受关注的知识权力,结合自适应知识交互行为,采用多主体建模与仿真方法,分析知识权力的动态变化导致的产业集群多重知识网络演化。结果表明:知识权力差距及知识交互行为是促使产业集群多重知识网络形成及演化的基础,产业集群多重知识网络的演化过程具有典型的阶段性特征,其网络结构呈现出网络节点密集性与稀疏性相结合、强联结与弱联结并存、度分布高度异质性的特征。利用实际产业集群网络验证仿真结果,证明了该仿真模型的可信性。     

浅析信息技术产业的网络外部性

网络外部性是指通过网络利用某一种产品或服务的人越多,每一个使用者从该产品或服务中所获得的利益也就越大。信息技术产业是一种典型的具有网络外部性的产业。信息技术产业的网络外部性引导企业进行开放化生产、追求主导业界标准、提供免费数字大餐。面对信息技术产业的网络外部性,本文提出了相应的对策建议。     

市场分割下中国加工贸易出口主体分化问题研究

外部采购与加工贸易是近年来出现的新贸易现象,对中国来说,低廉的劳动力成本是取得加工贸易比较优势的主要原因,加工贸易发展进程中出口主体的分化是中国从城乡二元劳动力市场向城市二元劳动力市场转变的结果,要继续保持加工贸易比较优势,就应该增强劳动力市场的流动性,实现劳动力市场的统一。     

Mobile Termination: What is the “Right” Charge?*

The regulation of fixed-to-mobile (F2M) termination charges has become increasingly important in Europe, Australia, and New Zealand under the Calling Party Pays principle. In the absence of any regulation, mobile operators have an incentive to set F2M termination charges “too high”. We show that the setting of the optimal F2M termination charges depends on the significance of network externalities, the intensity of competition in the mobile sector, and the distribution of customer preferences. We also discuss the merits of possible remedies which are not very intrusive. Tommaso Valletti has advised the European Commission and the UK regulator (OFCOM) on mobile termination and Frontier Economics has acted as advisor to a number of mobile operators on the same issue. The views expressed in this paper are those of the authors alone. We thank Carlo Cambini, Yulia Kossykh, participants to the 15th Biennial International Telecommunications Society Conference, the 3rd International Conference on Applied Infrastructure Research in Berlin, for their comments. We also thank the editor Michael Crew and two anonymous referees for many suggestions that have greatly improved the paper.     

创业网络的概念发展——一个系统的三维模型

创业网络研究已经取得了较为丰富的成果,但是对于创业网络概念本身还缺乏系统化的概念框架。本文对创业网络概念进行了界定,并且从关系主体、关系属性、关系产出三个维度对创业网络概念内涵进行了探讨,基于上述分析,本文提出了一个系统的创业网络三维概念模型。
