Innovation in digital technologies is central to contemporary debates about the need for policy and regulatory adjustment in response to the consequences of the centrality of these technologies in contemporary societies. Christopher Freeman's research in relation to changes in techno-economic paradigm and, specifically, in relation to the information and communication technology (ICT) paradigm, cautioned that assessments of these changes needed to go beyond market dynamics to examine social, cultural and political issues. In this paper several predominant themes in his work are foregrounded – the ambiguity of changes within the ICT paradigm; the role of guiding principles in influencing expectations about societal outcomes; and the importance of political factors in shaping the consequences of technological innovation. These three themes are then deployed in a discussion of recent innovations – two technical (5G mobile networks and artificial intelligence-as-a-service) and one institutional (proposals for changes in the international taxation regime in response to claims that the existing regime is inappropriate in the face of global online service provision). In each instance, the aim is to illustrate how following Freeman by giving attention to the themes operates as an important guide to analysis of adjustments to novel deployments of digital technology. The conclusion emphasizes the value of Freeman's contributions to shaping research agendas that acknowledge the need to humanize technology, to consider alternatives to taken-for-granted principles and practices, and to take into account the role of political power in tandem with concentrated economic power.  相似文献

Abstract

As Australia and other countries seek to establish biotechnology industries, it is timely to review successes and failures in this field. One of the most notable stories is the development of penicillin, as a wartime project, to which Australians made major contributions. Australians during and immediately after the war contributed much to the scientific identification and purification of penicillin, and to the industrial scaling up in its production at the Commonwealth Serum Laboratories in Melbourne. This was a classic instance of war accelerating innovations in public administration. Yet the nascent antibiotic industry was never allowed to gain international competitiveness, and was allowed to run down and eventually disappeared by the end of the 1970s. This article is concerned to tease out the puzzle posed by this contrast in aspirations, between the highest levels of scientific and technical achievement in bringing penicillin into widespread use (Australia being the first country in the world to provide penicillin to the civilian population in 1944) and shockingly poor performance in sustaining and developing a national antibiotics industry. As the stirrings of a biotechnology industry may be observed in the first decade of the twenty‐first century, it would be unfortunate to ignore the lessons of this earlier experience at the birth of the biotechnology era.  相似文献

Alkaptonuria, a metabolic disorder characterized by a triad of homogentisic aciduria, arthritis and ochronosis is one of the first conditions in the charter of group of inborn errors of metabolism proposed to have Mendelian recessive inheritance. It is due to the deficiency of the enzyme homogentisic acid oxidase which catalyzes the conversion of homogentisic acid to maleylacetoacetic acid in the catabolism of tyrosine. Homogentisic acid thus accumulates in cells and body fluids and its oxidized polymers bind to collagen, leading to progressive deposition of grey to bluish black pigment resulting in degenerative changes in cartilage, intervertebral disc and other connective tissues, leading to arthritis which is the only disabling effect in an affected older individual. However the diagnosis can be made in neonates when blackish stain is noticed in an unwashed diaper. Alkaptonuria is treated symptomatically, surgical intervention necessitates in advanced stages, treatment with ascorbic acid (Vitamin C) and dietary restrictions of food containing phenylalanine and tyrosine have proved to be successful in alleviating the symptoms.  相似文献

我国海外投资企业日益关注东道国创造性资产寻求,希望借此实现自主创新能力提升,那么如何获取东道国知识资源成为亟待解决的难题。在外商在华FDI活动中,我国企业往往借助知识和技术溢出效应获取资源和提升技术水平,而在我国向发达国家的OFDI活动中,这一方式则不太适用,我国企业需要更具主动性和针对性的知识获取途径和共享模式,而由海外子公司向母公司的针对性逆向知识转移则更能有效满足我国企业的特定资源需求,并有助于我国企业实现自主创新能力提升。本文试图从逆向知识转移方式出发,探究其作为我国企业获取东道国创造性资产路径的可行性,同时深入研究其影响因素和内在作用机制。为揭示我国跨国公司母公司微观因素对逆向知识转移的推动作用,本文围绕母公司战略因素和子公司逆向知识转移评价设计问卷,以我国海外投资企业问卷调研数据为基础,采用中介效应检验和结构方程模型探究了母公司国际化动因,子公司影响力对逆向知识转移的影响作用。实证结果证实以上两类因素对逆向转移的应用和创新效果具有促进作用,其中国际化动因体现为对海外创造性资产寻求的重视程度,子公司影响力从母公司对子公司的战略、文化和股权控制三方面实现对逆向知识转移的显著影响,而创造性资产的影响作用还通过转移意愿的中介效应体现,子公司影响力则借由渠道建设的中介作用实现。最后综合实证分析和华为案例佐证的结论,本文构建基于母公司战略和子公司影响力、转移意愿和渠道建设的逆向知识转移作用机制,为我国企业实践提供对策建议:(1)鼓励我国海外投资企业关注创造性资产寻求,尤其关注东道国技术、管理、市场和文化知识。(2)鼓励创造性资产寻求动因,提高对子公司的战略、文化和股权控制水平,提升子公司绩效对母公司的影响力,借以促进子公司逆向转移意愿;同时借由母公司控制程度提升,激励子公司完善渠道建设,实现基于编码和人员的双轨道知识转移系统,从而促进逆向转移效果。(3)增强全资子公司或控股合资等高控制度的海外市场进入模式实现更高水平的股权控制,同时通过对子公司的统一战略规划和资源支持加强其战略控制水平,通过构建更具内部凝聚力和控制力的强文化体系来加强对子公司的文化影响。(4)不仅关注逆向知识转移后的知识应用过程,更关注知识再创新和自主创新过程,实现后发国家的技术追赶。  相似文献

中国城市形状的时空变化   总被引:14,自引:0,他引:14  
基于国家资源环境数据库动态土地利用数据,计算了1990年和2000年我国31个大城市的形状指数.结果表明,从1934年~1990年的56年间城市形状从紧凑趋于非紧凑、分散;而在1990年~2000年10年间,由于受到城市建设用地控制增强的影响,城市形状趋于紧凑.从1934年~1974年间,在20个可比较的城市中有14个城市形状指数增加、6个城市形状指数减少.从1974年~1990年间,在22个可比较的城市中各有11个城市的形状指数增加和减少.从1990年~2000年间,31个城市中有11个城市的形状指数增加、20个城市形状指数减少.一些城市的形状指数在不同时间段变化十分剧烈.例如,兰州市是在1934年~1974年间形状指数增加最多的城市,而在1974年~1990年阶段则形状指数减少最多的城市.同样,武汉和昆明则是在1974年~1990年阶段形状指数增加量最大的城市,而在1990年~2000年阶段则是形状指数减少量最大的城市.这或许说明在城市规划和城市建设中,有时人们还未真正认识到城市形状的重要性,往往只有当城市形状变化到严重地影响人们的生产、生活和环境时,才发现形状存在的缺陷.  相似文献

An organization's future is viable to the degree it can create, obtain, and leverage its intellectual capital in an effort to manage knowledge for sustained, competitive advantage in the market place. Failure to do so can spell disaster. Case in point: Due to a festering crisis between his strategic intent and the organization's operational capacity to support it, in May 2000, the Spartanburg Regional Healthcare System (SRHS) board of directors voted for its chief executive officer (CEO) to resign. His resignation signaled the need for new learning, in addition to more effective management and communication practices in improving the identifying and codifying of knowledge and then facilitating the sharing of it organization-wide. This article focuses on delineating the process principles in managing a supportive environment necessary for the sharing of knowledge to spark creative thinking in devising innovative solutions that the hospital used in adapting to its market.  相似文献

General consumer and business finance companies have had limited success in serving the needs of economically active low-income families and micro-enterprises cost-effectively and sustainably in emerging economies such as China. Recent advances in computing and telecommunications technology are dramatically transforming this landscape by changing the way the financial industry operates. A key mechanism underlying this transformation concerns the use of big data in assessing, evaluating and refining the creditworthiness of potential borrowers and reducing the transaction costs. While China’s internet-only banking industry is currently small and some activities of players in this industry are akin to those in the shadow banking, this industry has potential to cause a major disruption in the Chinese financial market. A main objective of this paper is to examine the role of big data in facilitating the access to financial products for economically active low-income families and micro-enterprises in China. A second objective is to investigate how formal and informal institutions facilitate and constrain the use of big data in the Chinese financial industry and market. The paper also investigates how various inherent characteristics of big data – volume, velocity, variety, variability and complexity – are related to the assessment of the creditworthiness of low-income families and micro-enterprises. Case studies of big data deployment in the Chinese financial industry and market are discussed. The paper also looks at various categories of personal financial and non-financial information that are being used as proxy measures for a potential borrower’s identity, ability to repay and willingness to repay. Various business models involving the sources of data (internal vs. external to the big data organization) and providers of credits (big data organization vs. external partners or clients of the big data organization) are investigated. The analysis of the paper indicates that the main reason why low-income families and micro-enterprises in China and other emerging economies lack access to financial services is not because they lack creditworthiness but merely because banks and financial institutions lack data, information and capabilities to access the creditworthiness of and effectively provide financial services to this financial disadvantaged group.  相似文献

Contrary to canventional wisdom, semi-industrialized countries engage, to an appreciable extent, in R&D activities leading to technical change. Much of their technical change activity consists of adaptation of foreign technology to local inputs and market preferences, and is carried out in response to contraints and distortions prevailing in their economies. Moreover, in this context, limited consideration is given to cost reduction, since the main objective is to manufacture under protection and technical change becomes a complementary response to the productive effort.A key factor in the ability to engage in such technical change activities is the availability of technically competent manpower, including scientists, engineers and technicians. At the same time, previous investment in the formation of such technical skills may result in an “excessive” supply of skilled labor, which , coupled with import constraints, will induce eexcessive adaptation of machinery and equipment and may deter from the importaion of new technology embodied in such equipment. Conversely, a pronounced scarcity of technicl skills may impade the adaptation of technology and result in excessive importantion of machinery and limit local efforts of modification, adaptation, etc.Because of the eay technical change is generated, it does not necessarily follow that it is all cases beneficial to the national economies of the countries in which it takes place. However, proper cost benefit accounting of the social returns to technical change activities is complicated by the intractable nature of many of the indirect and secondary effects, like learning from the R&D, or the impact of adaptation to domestic inputs in the development of local suppliers, etc. Also, th interdependencies between technical change and production and between various technical change activities are little understood.conventionall economic theory has contributed little to the understanding of the technical development process. The analysis of technical change in terms of the market failure metaphor, while providing useful insights, is also not very as far as understanding the problem of not very helpful as far as understanding the problem of technical change in semi-industrialized countries is concerned, since the roles of uncertainty and externalities in that situation are quite different from those foreseen in the market failure analysis for industrializerd countries. Special attention should be given to the possible application of the metaphor in trying to improve our understanding of the problems arising in the use of technical information and not only its creation. This would be particularly helpful in connection with the technical development problems of small enterprises not enjoying the benefits of the devesion of labor which are possible in larger firms.  相似文献

Endogenous adenosine formed from ADP and AMP by the action of ATPase and 5′-nucleotidase is known to cause bronchoconstriction and asthma in humans. It has been suggested that this action of adenosine is due to its binding to specific purino receptors in the mast cells in the lungs and consequent release of mediators which elicit bronchoconstriction and asthma. The release of these mediators leading to asthma was also believed to be due to vagal stimulation by adenosine. Though the role of adenosine in causing bronchoconstriction leading to asthma is well confirmed the actual mode of action and details of the mechanisms involved in the clinical manifestation of asthma remain unclear.  相似文献

本文采用山西省1986年-2009年间的GDP数据与3类工业废弃物排放量(工业废水排放量、工业废气排放量、工业固体废弃物排放量)数据,基于VAR(向量自回归)模型,通过变量平稳性检验、协整检验、格兰杰因果检验和脉冲响应分析方法,研究了山西省GDP与工业废弃物之间的关系.结果显示:随着山西省GDP的增加,工业固体废弃物排放量有所增加,GDP对工业固体废弃物排放量有较大影响;GDP增加的同时可以实现工业废水排放量的减少,这与山西省废水资源化再利用有很大关系;GDP的增加对废气排放增加的影响不大.说明山西省通过采取措施可以在GDP增长的同时,降低废弃物排放.建议加强对工业固体废弃物资源化利用,并进一步加强对废气及废水排放的限制及治理.  相似文献
