基于信息熵的城镇居民消费结构演变分析——以福建省为例

从消费结构信息熵的基本理论入手,以1995～2006年福建城镇居民家庭消费构成数据、恩格尔系数、基尼系数为基本数据,分析得出城镇居民消费结构逐步升级且消费支出向更高的层面转换的结论。并针对未来的经济发展趋势,提出居民消费结构升级转换的若干对策建议。     

ICT growth effects at the industry level: A comparison between the US and the EU

This is an empirical study on the growth impact of Information and Communication Technologies using industry-level data for the US and the EU industries over the period 1980-2000. A panel data approach is employed to estimate the ICT effect using the system GMM and the pooled mean group panel data estimators. The results vary depending on the period, the region, and the type of industry considered. The GMM estimates suggest a significant ICT effect on growth during the 90s both in the US and in the EU. This effect for the EU was strong in the early 90s and weakened afterwards, as opposed to the US where it strengthened in the late 90s. The results of the pooled mean group estimator confirm that the long run growth contribution of ICT was significantly positive in the industries of both regions and over the entire period 1980-2000. However, it seems that the productivity effects of ICT are mainly present in the industries which are either ICT producers or heavy ICT users.     

Strategic Interaction between Governments and Investors under Privatization Programs

This article analyses the strategic moves of governments and investors under privatization programs in a game‐theoretic context. In sequential‐move games of both perfect information and incomplete information, the best response of the strategic investors to observing a slow pace of privatization is to have a low participation in economic activity because of concerns over public policy credibility. This is true even if the government chooses to randomize its action to send mixed signals to the investors while adopting a slow pace of privatization for budgetary reasons. However, the outcome is Pareto inferior to a situation of phased but fast implementation of privatization programs and high private‐sector participation under plausible assumptions.

Integrating information technology and marketing: An examination of the drivers and outcomes of e-Marketing capability

This research examines the performance implications of integrating information technology with marketing capabilities and other firm-level resources. Specifically, this study introduces and empirically tests a model that conceptualizes e-Marketing as the integration of complementary technology, business and human resources that, when combined, positively influence firm performance. The results from a survey of 522 Belgian firms highlight the importance of how market and technology orientation leads to e-Marketing capability and that this capability is shown to positively influence firm performance by improving customer retention and satisfaction. The results suggest that researchers and practitioners should pay special attention to the complementary resources that are needed to successfully implement IT-enabled marketing initiatives and that an emphasis on the technology alone may not be sufficient.     

Who shapes network neutrality policy debate? An examination of information subsidizers in the mainstream media and at Congressional and FCC hearings

Recognizing policy-making process as a communicative process, this study examines who has subsidized information relating to the net neutrality policy debate. Empirical data has been collected from net neutrality stories published in four national newspapers, as well as from hearings by Congress and the Federal Communications Commission (FCC), during the period of February 2004 through January 2009. Study findings reveal that corporate interests have played a significant role in subsidizing information on net neutrality, both to the public through the mainstream media and to legislators through Congressional hearings. Furthermore, study results show that experts played a larger role in defining net neutrality through the mainstream media and FCC hearings than they did through Congressional hearings. Finally, the role of advocacy group representatives was more apparent at Congressional hearings than via the other two available information channels.     

网络组织流程协同效应的生成机理研究

文章主要对网络组织流程协同效应的生成机理进行深入研究。鉴于学术界对网络组织流程没有统一的认识,文章在文献分析和逻辑推理的基础上,首先明确界定了网络组织流程的内涵,进而构建了网络组织流程协同效应的概念模型,最后应用多层次回归分析对所采集的数据进行实证分析,验证网络组织流程协同效应的研究假设。结果表明,网络中结点企业间的关系强度正向影响流程协同效应,而网络组织的治理机制在关系强度与流程协同之间起着调节作用,跨组织信息系统起着部分调节作用。该结论对于网络组织的治理实践具有一定的理论和现实意义。     

专用性人力资本、信息结构及创新模式选择

文章探讨了企业人力资本专用性和信息结构两个企业情境因素对企业创新模式选择的影响以及企业间合作动机的调节作用。企业参与合作的动机包括三个方面：与研究开发有关的合作动机,与技术学习有关的合作动机以及与市场进入等战略目的有关的合作动机。以我国企业为样本,以企业规模、产品发展阶段和产业地位作为控制变量进行了理论分析及实证分析,研究发现：人力资本专用性越强,企业越倾向于选择内部创新模式;信息结构以横向为主导的企业倾向于选择内部创新模式;反之,人力资本专用性弱及纵向信息结构与外部创新相对应。并且,通过层次回归分析发现研究开发动机会增强信息结构与内部创新模式的正向关系,而技术学习动机会减弱人力资本专用性与内部创新模式的正向关系。     

Advocacy and political convergence under preference uncertainty

We study the formation of advocacy groups and how they can impact policy outcomes by revealing information about voters׳ preferences to uninformed political candidates. We conduct a laboratory experiment based on a two-candidate spatial electoral competition setting where the policy preferences of voters are (initially) unknown and change over time. In the control treatment candidates learn about the preferred policy of the median voter through the voting outcome of elections. In the advocacy treatments, voters can organize themselves into advocacy groups in order to reveal their policy preferences. We find that voters often overcome the collective action problem of forming an advocacy group. In fact, we observe the formation of both informative advocacy groups, which convey new information, and uninformative advocacy groups, which do not. Overall, advocacy groups significantly speed up the convergence to the preferred policy of the median voter. However, advocacy does not lead to higher earnings as the gains from faster convergence are offset by the costs of group formation.
