自主可控提升军民融合企业的全要素生产率吗?——基于信息产业上市公司的研究     

石琳  王圣博 《科技管理研究》2019,39(14)

运用OLS、OP、LP三种方法对2011-2017年55家信息产业军民融合上市公司的全要素生产率(TFP)进行测算,并用DID、PSM-DID等多种方法对自主可控政策与企业TFP的关系进行了检验,实证结果表明：(1)军民融合企业的TFP整体上呈波动上升趋势,由2011-2012年低于其他企业发展至2017年略高于其他企业,但整体差异不大；(2)2014年以来逐渐加强的自主可控政策对于军民融合企业的TFP提升并没有显著影响,而是显著提升了企业的总市值,从而表明现阶段自主可控政策对于企业发展的深层次影响尚未完全体现。  相似文献   

Environment and Policy Factors Shaping Global E-Commerce Diffusion: A Cross-Country Comparison   总被引：1，自引：0，他引：1  

Jennifer Gibbs  Kenneth L. Kraemer  Jason Dedrick 《The Information Society》2003,19(1):5-18

This article examines the key global, environmental and policy factors that act as determinants of e-commerce diffusion. It is based on systematic comparison of case studies from 10 countries--Brazil, China, Denmark, France, Germany, Mexico, Japan, Singapore, Taiwan, and the United States. It finds that B2B e-commerce seems to be driven by global forces, whereas B2C seems to be more of a local phenomenon. A preliminary explanation for this difference is that B2B is driven by global competition and MNCs that "push" e-commerce to their global suppliers, customers, and subsidiaries. This in turn creates pressures on local companies to adopt e-commerce to stay competitive. In contrast, B2C is "pulled" by consumer markets, which are mainly local and therefore divergent. While all consumers desire convenience and low prices, consumer preferences and values, national culture, and distribution systems differ markedly across countries and define differences in local consumer markets. These findings support the transformation perspective about globalization and its impacts. In terms of policy, the case studies suggest that enabling policies such as trade and telecommunications liberalization are likely to have the biggest impact on e-commerce, by making ICT and Internet access more affordable to firms and consumers, and increasing pressure on firms to adopt e-commerce to compete. Specific e-commerce legislation appears not to have as big an impact, although inadequate protection for both buyers and sellers in some countries suggests that mechanisms need to be developed to ensure greater confidence in doing business online.  相似文献   

Leveraging Sunken Investments in Communications Infrastructure: A Policy Perspective From the United States     

Anthony G. Wilhelm 《The Information Society》2003,19(4):279-286

Bridging the digital divide between information and technology haves and have-nots has waned from the top of the national policy agenda in the United States during a time in which the sunken investments of the 1990s need to be leveraged. A national information network now exists yet this infrastructure--largely hardware--needs to be continually modernized and parlayed with commitments to building human capacity, developing relevant content, and scaling socially beneficial technology applications, such as telemedicine, in order to optimize these initial multi-billion-dollar outlays. This article makes the case that sidestepping public-private initiatives aimed at accelerating digital opportunity is imprudent, given the mounting empirical evidence highlighting the payoffs of information and communications technologies, when properly integrated and applied, especially in enhancing the life chances of underserved Americans. Policy next steps should advance the goals of expanding universal service initiatives, including hastening broadband deployment to homes and learning institutions, and deepening programs which leverage the utility of the existing infrastructure, such as expanding human-capital development, producing relevant content, and innovating socially beneficial technology applications.  相似文献   

The social strategy cone: Towards a framework for evaluating social media strategies     

《International Journal of Information Management》2016,36(1):1-8

Social media is growing rapidly. Providing both risks and opportunities for organizations as it does. The social strategy cone is developed for evaluating social media strategies. This framework comprises of seven key elements of social media strategies as based on a systematic literature review and case studies. The results of 21 interviews have contributed to the construction of the social media strategy cone for analyzing social media strategies. Three levels of maturity of social media strategy are proposed: initiation, diffusion and maturity. Initiation includes the key elements: ‘target audience’ and ‘channel choice’ while all case organizations studied payed attention to these elements. Diffusion includes the elements: ‘goals’, ‘resources’ and ‘policies’. Maturity adds the elements of ‘monitoring’ and ‘content activities’. Only 3 of the 9 organizations studied are in this phase of maturity. Although, theory suggests the importance of the element of ‘monitoring’ our research shows the need for more attention in practice.  相似文献

Using the Content of Online Privacy Notices to Inform Public Policy: A Longitudinal Analysis of the 1998-2001 U.S. Web Surveys     

George R. Milne  Mary J. Culnan 《The Information Society》2002,18(5):345-359

In the United States, Congress has had a long-standing interest in consumer privacy and the extent to which company practices are based on fair information practices. Previously, public policy was largely informed by anecdotal evidence about the effectiveness of industry self-regulatory programs. However, the Internet has made it possible to unobtrusively sample web sites and their privacy disclosures in a way that is not feasible in the offline world. Beginning in 1998, the Federal Trade Commission relied upon a series of three surveys of web sites to assess whether organizations post online privacy disclosures and whether these disclosures represent the U.S. definition of fair information practices. While each year's survey has provided an important snapshot of U.S. web-site practices, there has been no longitudinal analysis of the multiyear trends. This study compares a subset of equivalent individual-level web-site data for the 1998, 1999, 2000, and 2001 web surveys. Implications for using this type of research to inform public policy are discussed.  相似文献   

Do training institutions learn from experience?

This essay is concerned with organisational learning and, in particular, policy learning. Sometimes, organisations learn; sometimes they do not. Sometimes they use their acquired knowledge, but this is, not always the case.  相似文献   

Bridging research and practice: challenges and successes in implementing evidence-based preventive intervention strategies for child maltreatment     

Toth SL  Manly JT 《Child abuse & neglect》2011,35(8):633-636

Child maltreatment has been associated with a wide range of negative developmental outcomes for children and families as well as significant economic consequences. While efficacious intervention strategies have been demonstrated to reduce symptoms of trauma and to improve behavioral and emotional functioning, these models have not been widely adopted by clinicians. The challenges associated with exporting evidence-based interventions into community settings are discussed, along with an example of a preventive intervention program for young mothers, successfully implemented through a partnership of community agencies and funders.  相似文献   

Drivers of illicit drug use regulation in Australian sport     

Bob Stewart  Daryl Adair  Aaron Smith 《Sport Management Review》2011,14(3):237-245

Most Australian sport stakeholders not only believe that government regulation is a good thing, but also assume that intervention in the drug-use problem will improve sport's social outcomes and operational integrity. In this paper we examine the regulation of illicit drug use in Australian sport through an interrogation of two cases: the Australian Football League and the National Rugby League. Using Pierre Bourdieu's conceptual frames of social field, capital, and habitus, we aim to secure a clearer understanding of the drivers of Australian sport's illicit drug regulations by (1) identifying those stakeholders who set the drug regulation agenda, (2) revealing the values and dispositions that underpin these regulations, and (3) explaining how dominant stakeholders go about sustaining their position and marginalising those stakeholders with opposing drug regulation claims. Our results show that Australian sport's drug-use regulations are driven by a set of values and dispositions that views sport as an instrument for shaping the character of its participants, and drugs as a threat to sport's moral fabric and good standing. The dominant stakeholders, comprising the Commonwealth Government, its sport agencies, and the major governing bodies for sport, imposed these values and dispositions on peripheral stakeholders by designing a drugs-in-sport social field that yielded capital and power to only those participants who endorsed these values and dispositions. Peripheral stakeholders – including players, their agents, and drug-treatment professionals – who mostly shared different values and dispositions, were sidelined, and denied the opportunity of adding to their already limited supplies of capital, power, and policy making influence.  相似文献
