关于数字图书馆的经济学分析

描述我国数字图书馆寡头垄断的市场格局,分析数字图书馆的成本曲线,讨论数字图书馆服务的公共物品性质如何导致市场的稀薄以及数字图书馆服务商的定价策略,并对各种管制办法进行比较。研究表明,数字图书馆的产品属性、成本特点以及企业的利润最大化行为,将会导致价格提高,服务量变小。政府应该对数字图书馆服务市场实行一定的价格管制。     

中国学术数字信息资源市场中的买断博弈

对中国学术数字信息资源市场中数据库服务商的垄断行为进行博弈分析,并对市场监管部门及不同规模服务商提出发展建议。通过模型分析发现：由于不同信息资源需求的不均匀性,买断少量高需求资源可以提升企业效益,不过垄断进行到一定程度就会停止,且先行动者获益更明显;规模小的服务商有更大动力买断数字信息资源,规模大的服务商的报复行动对规模小的服务商的效益影响不大,所以规模小的服务商具有很大的意愿买断信息资源;允许各服务商保有一定量独占资源,鼓励深度挖掘及提供个性化服务是形成市场良性竞争的有效途径。

从市场结构看定制剧模式对电视剧产业的影响

定制剧模式会对中国卫视电视剧市场的市场结构产生负面影响,会增强其买方垄断竞争中的垄断程度,并减少针对卖方的市场需求,最终不利于中国电视剧产业的良性发展,当前应该对定制剧模式进行限制.     

我国电子图书数字图书馆建设现状的调查分析

为了解我国电子图书数字图书馆建设与数字出版市场现状,设计面向全国图书馆采购与使用电子图书数字图书馆情况的调查问卷,利用问卷调查法、统计分析法和信息计量分析法对调查结果进行分析,结果表明目前电子图书市场是以超星、方正、书生之家、中国数字图书馆为首的完全竞争市场,电子图书数字图书馆的发展依赖于政府支持、先进技术支持、读者素养的提高和采购经费的增加4个方面。     

基于产业融合的中国传媒产业市场结构特征研究

传统媒体的市场结构具有缝隙竞争的特征。在三网融合的背景下,我国政府采取了针对电信产业和广播电视产业的非对称规制措施,这使得传统媒体产业的政策性进入成本依然存在。但是,产业外替代性产品/服务的出现使得拥有垄断地位的媒介机构更多地采取竞争性策略行为,因而中国传媒产业市场结构出现了新的特征:一是缝隙竞争市场结构的弱化更多地源自传媒产业内部机构对新技术的利用或重组,而不是来自于产业外企业的进入;二是中国传媒产业市场具有了一种动态的竞争和垄断,双双被强化的市场结构——竞争性垄断。     

网络价值转变与信息传播——美国废除网络中立法的反思

网络中立原则自创制起就成为不同利益集团博弈的目标。从信息传播的角度看,非中立网络不但会阻碍和限制草根用户的内容生产权,而且也会对内容服务商的网络参与进行把关,甚至形成垄断。本文认为,基于电信运营商的属性和维护普通用户信息使用权的角度,我国需要坚持网络中立原则。     

2005：外资投资中国电视业展望

2005年。外资投资中国电视市场的规模和数量虽然会有陵大增长。但不会出现如某些分析人士预言的外商投资高潮。碌因一是目前对外资开放的只有电视节目制作领域．且不能涉足时政新闻节目的制作。而数字付费频道的经营目前国内政策仍然不允许外资参与经营：二是很多境外媒体已经在中国开展了很多电视业务，现在他们首先想做的是将以前做的很多事情争法化、公开化．大规模的追加投资倒未必会出现。     

我国媒介广告市场集中度分析

市场集中度是通过市场参与者的数量和参与程度来反映市场的竞争或垄断程度的基本概念,通过对报业和电视媒介广告市场绝对集中度指数的计算,分析报业和电视媒介广告市场的市场结构和竞争状况。     

论传统图书馆与数字图书馆的关系

论述了传统图书馆与数字图书馆的关系：传统图书馆是数字图书馆的基础，数字图书馆是传统图书馆的发展。在数字图书馆时代，传统图书馆不会消失，会有它特殊的地位与作用：在“藏”的方面，它会返朴归真，回归对“藏书楼”的性质，在“用”的方面，它会成为一种高消费的场所。     

Media Concentration in the Hispanic Market: A Case Study of TV Azteca vs. Televisa

If one wanted to measure the historic level of multimedia industry concentration in Mexico, it would not be necessary to use statistics, financial analysis, viewer ratings, or other evaluation systems. The maximum level of concentration is 1, and, in Mexico, that number belonged for 20 years to Grupo Televisa (1973–1993). Televisa's position was lost in 1993 when entrepreneur Ricardo Salinas Pliego launched TV Azteca. This paper explores the principal strategies used by TV Azteca to overcome the entry barriers set by the Televisa monopoly. The paper also presents an economic valuation of this duopoly market 7 years after the shift in market structure.     

Direct Competition in Cable Television Delivery: A Case Study of Paragould,Arkansas

In this study I explored the effects of the development of direct competition in the delivery of cable services to a small Arkansas city. The emergence of competition produced lower prices, better customer service, increased choices in programming, and technological improvements as the market structure moved from monopoly to duopoly and achieved an equilibrium in which each service company serves a 50% market share. Because neither firm is producing a profit under the current situation, I argue that in the long-run the competitors may switch to oligopolistic pricing behavior and focus on nonprice competition in an effort to achieve profitability.     

公共信息的供给方式分析

目前中国的公共信息公开主要注重于满足公众的信息需求,较少从公共信息供给的角度分析公共信息公开问题。偏重公共信息需求,缺少考虑公共信息供给会造成供给缺乏激励,供给方式不合理等问题。通过对公共信息供给的市场情况分析,讨论竞争和垄断条件下公共信息供给的均衡结果,演绎公共信息供给的理论模型,提出公共信息供给的管理策略。     

Determinants of Cable System Product Diversification—An Investigation of the U.S. Cable Systems

This study examines cable system diversification into three nontraditional services: pay-per-view television, high-speed Internet access, and telephony. An econometrics model based on the Industrial Organization Model is used to explore the factors that have led to variation in diversification among cable systems. Specifically, this study examines how three sets of variables, namely, cable system characteristics, market structure, and market demographics, influenced cable system diversification. Multiple linear regression was performed to identify the determinants of cable system total degree of diversification, which is defined to be the number, from 0 to 3, of the three nontraditional services offered by a cable system. Regression results indicate that Multiple System Operator (MSO) ownership, the number of basic cable service subscribers, and the number of broadcast television stations receivable over the air all had a statistically significant positive relationship to cable system total degree of diversification, whereas the number high-speed Internet service providers in a cable franchise area had a statistically significant negative relationship to cable system's total degree of diversification.     

Strategies to advance the dream of integrated digital public service delivery in inter-organizational collaboration networks

Public administrations are increasingly relying on collaboration within inter-organizational networks to coordinate the development and provisioning of integrated digital public services. Collaboration strategies are necessary to focus collaborative efforts, align and prioritize goals, and leverage concrete results that advance integrated service delivery (ISD). However, literature on inter-organizational collaboration strategies for integrated service delivery is scarce. This research identifies collaboration strategies in three qualitative case studies in Belgium. The cases present 33 collaboration strategies categorized into engagement, motivation, and joint action strategies. Collaboration strategies should complement each other. Together these strategies can help to overcome the adoption paradox, one of the key issues to advance ISD, which refers to service providers not being inclined to adopt an ISD unless it has many users, but users might not be willing to use and ISD before many service providers have adopted it. Policy-makers can use the identified collaboration strategies to advance integrated service delivery.

Academic e-Book Publishing in China: An Investigation of Current Status and Publishers' Attitudes

This study investigates the current status and attitudes towards academic e-book publishing by mainland Chinese academic publishers through an online survey. This study collected survey data from 49 authoritative academic publishers in China, focusing on their e-book sales profiles and their perceptions of how e-book sales affect publishers and libraries. The data reveals that China's academic e-book industry is still at an early development stage and has a relatively small market. The findings show significant differences in the willingness and attitudes towards e-book publishing between SSH publishers and STEM publishers, and also demonstrate that the enhancement of the demand for e-books by academic libraries promotes the process of the digital transformation of academic publishers. This study then argues that Chinese academic publishers need to further improve the quality of academic e-books, accelerate the transition from academic content providers to academic content service providers, and strengthen their cooperation with stakeholders.
