RTA框架下的数字贸易规则正在快速发展,且呈现非均衡性特征。一方面,“数字鸿沟”的内涵不断扩展和延伸,逐渐由有形的“信息鸿沟”向无形的治理壁垒扩展,并深刻影响数字贸易规则的制定;另一方面,区域一体化框架下各经济体间的依赖度和相互影响力不断增强,使得数字贸易规则中的结构性力量不容忽视。为此,本文采用指数随机图模型,对RTA数字贸易规则网络形成的影响因素展开实证研究。结果表明:RTA数字贸易规则网络在数字贸易规模和数字技术水平方面呈现“马太效应”,在数字治理方面具有同配性。网络内生结构方面,网络的偏好依附和连通性均会影响RTA数字贸易规则网络中的关系形成。异质性分析结果表明:由于数字治理存在壁垒,发展中经济体仅发展数字贸易和数字技术是无法促进其参与RTA数字贸易规则网络的;经济体双方在数字服务贸易限制上的差异越小,达成RTA数字贸易规则的可能性就越高。进一步的机制研究验证了网络内生结构在RTA数字贸易规则网络关系构建中所产生的重要作用,网络内生结构在一定程度上解释了网络形成中的“马太效应”和“同配效应”。多层ERGM分析显示,各因素对不同规则条款网络影响呈现差异化特征,同时各规则条款网络间... 相似文献

在现代社会,制造业是一切物质生产产业的支柱,信息产业与服务产业的设备也需要制造业提供,制造业是高新技术产业化不可替代的载体和基础。当前,“中国制造”时代正在到来,中国日益成为“世界工厂”;发达国家已将用信息技术改造传统产业、改造制造业、改造企业作为一项重大战略。我国要想真正由“制造大国”变成“制造强国”,在国际市场上赢得竞争优势,就必须加快用信息化带动工业化,打造数字化的中国制造业。将于2004年11月4日—9日在上海举办的国际数字制造展览会,以“展现信息化带动工业化的道路,代表装备制造业技术发展方向”为主题,通过展示被称之为“数字化装备”的各种先进设备和被称之为“智能载体”的各种先进软件,给人们带来关于21世纪制造业发展的具体图景,带来称之为“制造业信息化整体解决方案(ALL IN ONE)”的先进理念,必将推进我国制造业数字化的进程。 相似文献

2010年1月1日,历时10年建成的“中国-东盟自由贸易区”正式全面启动。在该自由贸易区内,人口高达19亿,GDP之和接近6万亿美元,年贸易总额高达4.5万亿美元,也将成为仅次于欧盟和北美自由贸易区的世界第三大自由贸易区。作为中国对外参与组建的第一个自由贸易区,中国-东盟自由贸易区将为“中国制造”在亚洲市场上进一步发展做出积极重大的贡献。 相似文献

This paper analyses the influence of the digital divide on the new IMF financial development index on a panel of 34 African countries over the period 2005–2017. Using the instrumental variables technique, we arrive at the main result that ICT divide is a severe handicap for the financial systems development in Africa. The use of financial development sub-indices relating to financial institutions and financial markets, as well as their dimensions confirms the negative effect of the digital divide. Our result remains stable when we use alternative measures of financial development and ICT indicators. Furthermore, we found that the digital divide between countries is also a severe handicap for the financial development of countries lagging behind. On the other hand, countries with a technological lead or a digital dividend have relatively developed financial systems. Some recommendations have been suggested to promote digital penetration in Africa, as well as to improve the receptivity and flexibility of African financial systems. 相似文献

This paper estimates the regional effects of high-speed broadband coverage on economic growth in a panel of 1348 regions across all European Union Member States between 2011 and 2018. We distinguish between different connectivity speed levels by aggregating the available regional data across all existing broadband technologies, and investigate how regional differences in the contribution of broadband coverage to real economic growth can quantitatively explain the persistence of the European urban-rural digital divide. In order to make our results robust to endogeneity and disaggregated data availability issues, we employ a bootstrap-based bias correction for the dynamic fixed effects estimator. We find that expansions in the provision of lower-speed broadband access accelerated annual per capita growth in both urban and rural regions through diminishing returns to scale, but that the effects were weaker in those regions characterized by larger ruralization. High-speed broadband coverage, on the contrary, could only be significantly related to rural economic growth and had no impact within their urban counterparts. We find evidence that the costs of these high-speed rural connectivity expansions had not yet been offset, but that they exhibit increasing returns to scale with cut-off levels nearing full coverage. These results indicate that the high-speed digital expansion of rural Europe is a potential gamechanger for further rural development policies through its role as a general-purpose infrastructure, and consequently argue in favour of increased efforts to close the urban-rural digital gap. 相似文献

We generalize and extend the sequential model proposed by the resources and appropriation theory to explain the digital divide in the European Union plus the United Kingdom (EU27+UK). We measure the theoretical constructs of the model with data provided by the EU and test the theoretical predictions using a partial least squares structural equation model. We find support for the hypothesized relationships but find that the effects vary depending on the digital development level of countries. While education overall is the primary determinant of the social production of digital inequalities, a country's digital development level is crucial for less well-educated Europeans. These findings have theoretical and practical implications: (1) they call into question the homogeneity of the effect of causal relationships and the assumption that individuals differ only in terms of motivation, access, and digital skills, and (2) they indicate that socially disadvantaged Europeans benefit from living in more digitally developed countries. 相似文献

产业链定位、分工与集聚如何影响企业创新——基于江苏省制造业企业问卷调查的实证研究 总被引:20,自引:0,他引:20
本文利用对江苏省342家制造业企业的调查问卷实证研究了产业链定位、分工和集聚效应对于企业创新强度的影响,结果发现:处于产业链终端环节企业并没有表现出特定的创新优势,一定程度上反映出我国制造业产业链中的终端集成环节并未形成相应市场势力或集成创新能力;分工活动(以供应商数量作为度量指标)与创新强度之间呈现较为复杂的U型非线性关系;集聚效应并未对我国微观企业创新活动产生积极影响,未成为激发集群创新动力的有机载体。针对以上实证结果,基于我国经济转型背景和企业微观层面行为特征,我们就产业链定位、分工与集聚效应三个因素与我国制造业企业创新活动的内在关系与作用机理,结合统计性分析进一步进行了剖析和解释,并据此提出了相应的可行对策思路。 相似文献

The authors examine the broadband digital divide by analyzing the impact of policy and regulation on broadband Internet diffusion. Their multiple regression analysis shows factors that determine broadband diffusion in technologically developed countries do not necessarily have the same impact in less developed countries. They show that in technologically developed countries, there is greater broadband diffusion in countries that make a higher financial investment in information and communication technologies (ICTs), have effective governing practices at the national level, have higher levels of education, and are more urban. In technologically developing nations, a competitive telecommunications sector and higher investment in ICTs lead to greater broadband diffusion, with investment having an even larger impact in the developing world than in the developed world. In addition, stronger democratic political institutions, higher levels of national income and lower levels of income inequality increase diffusion, but the presence of a national telecommunications regulatory authority has a negative impact. These results suggest that the path to widespread availability and use of broadband requires different strategies depending on a nation's level of technological development. 相似文献
