Abstract

During the Industrial Revolution, manufacturing and related commercial activities led to the evolution of “dense cores” of heavily populated areas. Fundamental to the operation of these industrial‐commercial cores was the development of service activities—banking, risk‐bearing, legal services—which depended on rapid exchange of information or quick “cycle times of information” for effective decision making and allocation of resources. As these cores radiate resources away from the central body toward less populated areas, the need for short cycle times of information in rural areas has become apparent. For example, modem agriculture is an enterprise that requires short time cycles of information exchange. The technology for building computer‐based information networks to facilitate the desired rapid transfer of information exists. However, the installation of hardware linked by reliable, cost‐effective communications networks is only in the beginning stages. One computer‐based information network that has successfully met the challenges of rapid transfer of agricultural management information to farmers is the University of Nebraska's AGNET system.  相似文献

The paper draws upon a national study to analyze two issues relevant to the future effectiveness of the American agricultural technology system: (1) linkages between research and technology transfer activities; and (2) relationships between the public and private sectors. Increased commitments to basic research by the US Department of Agriculture and the state agricultural experiment stations have served to exacerbate existing strains between research and technology transfer functions and units. Both the feasibility and desirability of having USDA's Agricultural Research Service simultaneously seek to strengthen its basic research capabilities and its commitment to technology transfer have been questioned. Within the landgrant universities, multiple pressures have served to attenuate traditional ties among agricultural researchers, extension specialists, and county extension agents.Private sector activity in agricultural research and the provision of technical information has increased following the expansion in the domains of knowledge over which firms can establish property rights and the concentration of production in a smaller number of economic units. Adjustments in the activities of the public sector in response to these changes can be seen. Still, the optimal mix of public-private sector activities in both research and technology transfer has yet to be fully analyzed. Current analyses (and public policy) are excessively constrained by the “property rights” approach to technological change.  相似文献

资源的循环特征与循环经济政策   总被引:42,自引:3,他引:42  
沈镭 《资源科学》2005,27(1):32-38
世界经济的持续增长带来的"资源危机"或"资源安全"问题,促使人们寻求资源集约型经济和循环经济的新理念.本文旨从对资源循环特征的分析出发,探讨了资源循环利用与资源产品链之间的相互关系,提出了资源流动、资源循环利用与循环经济理论的科学内涵,指出了发达国家政府实现循环经济的宏观调控政策和手段.作者认为资源之所以能够循环利用是由资源产品链特性所决定的,资源的循环利用具体表现为循环经济活动过程,并通过闭环的资源流动来实现,任何资源都不会成为废物无限期地积累在环境中,而总是处于特定的和永久的循环中,它们的存在形式却在不断地发生变化.资源循环利用是实现循环经济的最重要的手段之一,可以通过"3R"提高资源的利用效率.循环经济理念是基于资源开发技术的创新,是资源利用方式的一种变革.资源循环利用在循环经济活动中具体体现为产业、区域和社会三个重要层面.作者还建议制定和完善有利于资源循环利用的法律体系,优惠的资源再生和回收利用经济政策,充分发挥社会中介组织在资源循环利用方面的积极作用,鼓励社会公众广泛参与并以实际行动加入到资源循环利用活动中来.  相似文献

This study aims to investigate the main factors driving technological innovation within firms in the manufacturing and service sectors of the Czech Republic. We apply a binary logistic regression model to cross-sectional data from 502 firms, obtained from the World Bank Enterprise Survey. The results of our empirical investigation show that certain elements of the business environment, such as the tax rate, serve as significant obstacles to firms’ product innovations. The results also confirm that international technological linkages—measured by international quality certificates and foreign technology licenses—affect technological innovations. Moreover, we found that internal R&D activities positively impact technological innovation across all sectors; contrarily, we found that process innovation in the manufacturing sector is positively influenced by foreign technology licenses and business association membership. Process innovations in the service sector are positively correlated with external R&D and financing from banking institutions. Finally, business association membership does not positively influence technological innovation in the service sector. Our findings have salient implications for firm managers, policymakers, and scholars aiming to explore and improve innovation outcomes in transitional economies.  相似文献

The study examines selected roles of the information sector in the national economy. Among the findings are the following: (1) the information sector conducts relatively little international trade, in comparison to its domestic activity. Roughly 12% of U.S. exports are attributable to the information sector; over 97% of the sector's output is sold within the U.S.; and the sector's exports account for only a small fraction of 1% of GNP. (2) The historical pattern of employment shows that the portion of information workers has risen from 8% of the U.S. work force in 1870 to 41% in 1970. Relatively little of this growth is the result of new technological innovations such as telephones, radio, television and, more recently, computers. Rather, the growth of public and private bureaucracies, which now total 26% of our total work force, largely explains the growth of the sector. (3) Unemployment within the information sector has consistently been lower than in either the manufacturing or agricultural sectors of the national economy. (4) Since 1967, the high technology elements of the information sector, such as electronic components, computers and telecommunications equipment have experienced appreciably less price rise than has the economy as a whole. However, over the same time period, the service elements of the sector, including finance and insurance, education and medical care, have experienced greater rates of inflation than has the economy as a whole.  相似文献

服务化是在我国实体产业发展出现困局的当下产业升级之路,本文将从“营改增”的准自然实验角度出发分析税制改革对工业企业服务创新的影响,尽管“营改增”在学术界内普遍被认为是为服务业发展松绑之举,但由于行业市场供需弹性以及税收转嫁等问题,不同产业部门内营改增对于企业涉足服务业的影响程度存在差异,本文通过选取我国上市制造企业在2012税改省际试点的前后期间几个季度的平衡面板数据进行的双重差分检验,实证研究结果证实在试点省内企业服务化程度受税改的促进作用更甚,且不同行业部门内税改对试点组与对照组企业的影响差异也是不同的。  相似文献

Economic policy in Hong Kong is frequently cited as a shining example of the laissez‐faire model for development, with minimal government intervention. However, the government has played a bigger role in the economy than is often recognized, responding to market failures, social problems, and the needs of the business community. Information technology (IT) policy in Hong Kong has mirrored the colony's laissez‐faire economic strategy, with little government effort to promote the production or use of IT products and services. Hong Kong has become an advanced user of IT in several economic sectors and an assembly site for personal computer hardware. However, like much of the manufacturing sector, the computer industry is moving much of its production to China, causing concern about the future of Hong Kong's economy. While some people feel that Hong Kong can flourish as a financial and business services center, others feel that this role will be diminished as the Chinese economy liberalizes and other centers develop in mainland China. They argue that Hong Kong needs to upgrade its technological capabilities and develop technology‐intensive activities such as R&D and software development to complement China's manufacturing activities. The government has begun to respond with limited measures to encourage R&D, train more scientists, engineers, and managers, and support technology start‐ups. Hong Kong has the potential to develop software and information services industries to serve the Chinese market. It also can apply IT to other sectors to maintain its leadership as a financial, business services, transportation, and communications center.  相似文献

This paper, using Thailand as a case study, aims at understanding the national innovation system (NIS) in developing countries which are less successful in technological catching-up. In contrast to developed countries, the development level of Thailand’s NIS does not link to its economic structural development level. As Thailand moves from agricultural to an increasingly industrial economy, its NIS remains weak and fragmented. The mismatch between the two affected Thailand’s competitiveness and partially contributed to the recent economic crisis. Studies of NIS in countries like Thailand should focus on factors contributing to the long-running perpetuation of weak and fragmented NIS.  相似文献

农户生产要素投入的方向和强度不仅反映了农户的经济行为特征,也在一定程度上决定了区域农业的发展方向。本文以北京市平谷区2003年的116个农户调查问卷为基础,对大城市郊区农户生产要素投入特征及其差异进行了分析。结果表明,由于预期收益不同,农户在各产业的劳动力投入数量、质量、物质投入水平和组合结构具有很大差异。在劳动力质量和数量投入方面,根据建立的劳动力质量投入模型进行计算,平谷区农户劳动力质量投入水平非农产业要高于农业产业,经济作物要高于大田作物,具体从高到低的顺序依次是非农产业、其他经济作物、畜牧业、菜地、果园、大田作物,同时劳动力从农业向非农产业、在农业内部从大田作物向经济作物转移的趋势明显;在农户物质投入水平和组合结构方面,资本投入水平从高到低的顺序是:果园、菜地、大田,要素投入组合结构从好到差的顺序是:菜地、果园、大田,两个排序中经济作物都要高于或好于大田作物。分析认为稳定市场预期对于大城市郊区农业的健康发展具有十分重要的意义。  相似文献

The relationship of technology policy to economic and industrial development has become a subject of debate between those who argue that market forces should determine how technology is produced and used and those who believe that government has a role in supporting investment in technology use and the development of high‐technology industries. This article looks at the effects of national technology policy in promoting the production of computer hardware and software in Asia‐Pacific countries during the 1980s. It also analyzes the relationship between various environmental factors and computer production and looks at the interaction between environment and policy. It finds three types of environmental factors associated with level of computer production: human resources, in the form of scientists and engineers; the presence of complementary industries, particularly electronics production; and expenditures on research and development. It also finds that hardware production is higher in countries with national computer plans but that software production does not appear to be associated with efforts by the government to promote the computer industry.  相似文献
