Disparity in the level of digitalization is a crucial driver of economic inequality in an economy. Although a pocket of its population is still bereft of the benefits of digitalization, India currently has the second highest number of internet subscribers in the world despite the nation's late adoption of digital technology. An accurate assessment of the current state of digitalization in the country is required for devising effective initiatives towards building a Digital India and bridging the nation's internal digital divide. Considering 17 major Indian states and 21 variables for 10 years, we constructed a composite index of digitalization with the help of Principal Component Method (PCM). This paper identifies factors responsible for the digitalization divide across states. In the second part of the analysis, the study confirms, with the help of club convergence test, the absence of overall convergence towards digitalization and the existence of the non-convergent group. This paper also shows that the non-convergent group of states are at the bottom of the ranking table which indicates the need for greater attention to initiatives to bridge the digital divide. 相似文献

The possible implications of global trends such as climate change and resource scarcity on food security are high on the political agendas. While the food sufficiency aspect of food security takes centre-stage, the future of food safety and nutritional quality of diets often seems to be taken for granted. This paper builds on the results of a foresight study on EU food safety and nutrition towards 2050 to discuss potential future points of tension for food policy. Increasing food production while using fewer resources and reducing food waste while ensuring food safety are just two examples. Innovation at different levels in the food system will be needed to address future challenges. Fast technology uptake and the launch of new food-related products can put pressure on the ability to deliver timely risk assessments, the scope of which might also need to cover other legitimate factors. Future food policies need to be more sensitive to impacts on food safety and nutrition and health aspects. A holistic food systems approach must be taken to identify and discuss in advance possible tensions and trade-offs and to address them upfront in a systematic and transparent manner. 相似文献

This study investigates the contribution of modern communication infrastructure characterized by high speed broadband access network on the productivity growth, production structure and factor demands for US industries and for the aggregate economy. To evaluate such contribution, we modify the traditional cost function by incorporating communication infrastructure as input in production process in conjunction with other public infrastructures. The network externality and spillover effect of broadband access technology are captured by introducing broadband penetration rate as a shift factor in industry level production function. Empirical results show that the increased use of modern communications infrastructure increases the productivity of all industries with wide variations across industries. Estimated impacts on input demands show that increase in use of communications infrastructure service saves labor and materials and increase the demand for private capital. Finally, aggregate social rate of return on such investment has been estimated for policy implications. 相似文献

基于专利技术关联度的中间人角色划分方法研究 总被引:1,自引:0,他引:1
基于专利数据构建的发明人合作网络有助于分析发明人中间人角色,揭示发明人创新合作规律,对于企业研发人才管理和知识管理具有重要指导意义。群体划分是中间人角色划分的一个关键步骤,以往文献大多基于网络结构或者给定网络边界进行群体划分,忽视了专利发明人的知识交流环境和特征。鉴于此,基于专利技术关联度,利用专利著录项中的IPC分类号信息判断企业发明人所属技术知识领域,再以技术知识领域为边界设计一套算法,将发明人归入互斥子群,最终对中间人角色进行高效划分,寒武纪公司数据验证了中间人角色划分算法具有较高的准确性和有效性。 相似文献

This study assesses the level of sophistication of livestock products in Africa by evaluating technology intensity and economic complexity of each product. Using trade data from 1995 to 2012, livestock commodity exports are classified based on technology intensity. Employing a method of reflection in computing the economic complexity of export products, we find that one fifth of African livestock commodity exports are manufactured with low technology while the rest is composed of raw materials. The results also show that the ten most complex livestock commodities represent about a third of African livestock total exports while the world level is almost double this figure. Yet African countries spend a huge share of their wealth on importing complex products. The results imply that by exporting non-complex products Africa loses nearly a third of the total value of its livestock exports. To boost the value of livestock products, African countries should exploit their untapped potential while securing the domestic market to achieve import substitution. This can be done by integrating with global value chains or developing niche markets at the regional or international markets and improving productive capabilities. 相似文献

The various ways in which livestock production systems can be incorporated into economic, partial-equilibrium, multi-market models are presented, and the challenges outlined. A particular focus and illustrative case is livestock feed. Foremost among the challenges is the reconciliation of scientific understanding of livestock feed requirements and production characteristics with the available national data. Another challenge is in estimating herd structures. An economic, multi-market modeling approach is presented which has been widely used in policy analysis and advocacy, and an account is given of the necessary recent enhancements for addressing livestock. 相似文献

Asian countries are becoming more and more active in participating technology standard development. In this paper we study the impact of this change on multinational enterprises (MNEs) using the case of TD-SCDMA, an international technology standard of 3G mobile communications. During the development of this technology standard, MNEs׳ market share dropped dramatically. A major contribution of this study is analyzing the underlying mechanism governing MNEs׳ interpreting TD-SCDMA as a threat rather than an opportunity by integrating two streams of literature. We also discuss the possible strategies for MNEs to maintain their market leadership position when local firms are able to lead international technology standard development. 相似文献

The PASHMINA (paradigm shifts modeling and innovative approaches) project grew out of the need to improve our understanding of the paradigm shift in the energy-transport-landuse nexus and, more broadly, in world development. In envisioning the world at 2050, we envisaged future growth in four possible directions: growth without limits, growth within limits, stagnation, and New Welfare. The scenario considered as preferable reflects a transition toward a New Welfare, characterized by a high level of cooperation, heightened concern for the environment and for social welfare, and an increased share of immaterial consumption. This scenario is based on the recognition that the development of new technologies – although relevant – turns out to be insufficient to resolve the issue of resource scarcity alone. Important behavioral changes are also needed. In the New Welfare scenario, GDP as a measure of growth becomes obsolete and needs to be replaced with ways of measuring progress that are more reflective of natural, human, and social capital. The New Welfare scenario also charts a pathway toward a low-carbon future, with an overall reduction in energy consumption, density, and intensity, and a greatly reduced reliance on fossil fuels. A new, smart electric grid facilitates active demand management and decentralized production of power. Natural gas or even small nuclear plants tackle problems associated with the intermittency of renewable energy sources. Among other likely shifts under this scenario is a re-conceptualization of production, from short-lived to longer-lasting goods and from private to open source knowledge products and services; growth in recycling and zero-waste processes; and a shift from profit-driven business to entrepreneurship that seeks to satisfy social needs and build local capital. The world undergoes a transition from unequal growth to prosperity in a multi-polar, globally interdependent world. New global democracy networks and institutions are created, and constitutions extend beyond the protection of human rights to the recognition of “nature rights.” Citizens’ income is tied to the social welfare-oriented duties and participatory governance. This scenario further leaves room to new forms of self-regulation of common resources. Actions necessary for the shift to the New Welfare paradigm include the adoption of new metrics for measuring progress, measures to increase public acceptance of technological and societal change, the creation of new global and local institutions devoted to sustainable management of shared environmental resources, sustainable production and consumption patterns, and a low-carbon energy and transport systems. 相似文献
