Tradeable permits,missing markets,and technology

This paper examines the effects of missing markets, heterogeneous pollutants, and the pollution technology of firms on the efficacy of transferable pollution permits. Under the assumption of perfect competition in all markets, we show that if firms can substitute among pollutants, then setting the optimal number of permits for only one pollutant will not, in general, lead to an efficient outcome. The degree of the inefficiency will depend on the information set available to the regulator and the substitutability among pollutants by firms. When establishing transferable pollution rights regulators should, therefore, consider the technology of firms. If firms discharge pollutants in the same fixed proportions, then the regulator need only set a market for one of the pollutants to ensure an efficient outcome. Where firms can substitute among pollutants, however, establishing a market for only one pollutant provides an incentive for firms to substitute to unregulated ones. This is an important policy issue as substitutability among pollutants within and across production processes may dampen the dynamic advantages of a tradeable permit policy.     

Transfer sciences: management of distributed knowledge production

This paper is concerned to develop the notion of transfer science to take account of what is perceived to be the emergence of a new mode of knowledge production. The new mode which is characterised by the production of knowledge in the context of application, by transdisciplinarity, by homogeneity and organisational diversity, by enhanced social accountability and reflexivity, and by new forms of quality control. The thrust of the new mode of knowledge production is to call into question conventional notions of knowledge transfer and focuses instead on the organisational and managerial implications of the emergence of a socially distributed knowledge production system. The paper concludes with a brief discussion of the policy implications of the emergence of the new mode of production. Needed in the new mode are science and technology policies which promote institutional permeability and policies which enable governments, acting through their civil service to act as brokers in the new knowledge production process. Such brokerage is necessary to enhance permeability between institutions within a particular country but also to increase co-operation and collaboration between institutions across countries.     

Problem-solving in teaching/learning packages for Technology

In the project Technology in Secondary Education: Problem-solving in Teaching/learning Packages, two experiments regarding a construction problem and an explanation problem were conducted, in which two variants of a teching/learning package (strongly structuredvs. weakly structured) were compared. Only with the strongly structured instructional variant of the package for the explanation problem did the pupils come to a quick solution of the problem. In both experiments, the factors that influenced the problem-solving processes of the pupils were investigated. The results are of importance for curriculum developers and the authors of teaching/learning packages for Technology but further research into the factors influencing the problem solving process of pupils is necessary.     

论我国税收激励制度的完善

税收激励主要通过收益调节、现金流量的可获性和风险分担这三种方式发挥其作用。我国目前的税收激励的主要不足在于，缺乏一种系统的、一以贯之的政策取向。从知识经济的大背景看，完善我国的税收激励制度应紧紧围绕促进科技创新这一主线来进行。     

审计市场中的合并、产业专用化投资和价格竞争

本文从产业组织的角度，分析了审计市场的合并、产业专用化和价格竞争等竞争行为，并进一步探讨了这些行为对审计质量和社会福利的影响。本文认为，审计质量的信号传递机制推动了产业中的合并行为，而审计产业的专用化投资行为在于策略性地阻止进入。由于审计产品的异质性、信任品特性以及强大的买方谈判能力使得审计市场存在激烈的价格竞争，而合并和产业专用化投资有助于事务所降低成本。因而，审计市场的竞争提高了社会福利。     

信息技术对竞争景框的影响--对波特观点的完善与修正

在分析信息技术对企业的影响时，波特教授对竞争景框变化的论述并不全面和完全正确。不全面在于，他只述及信息技术对地理景框和产业景框的影响，没有提到另两个方面——细分景框和纵向景框的变化。不正确在于，他笼统地提竞争景框的扩大或缩小，而竞争景框四方面在外力作用下变化并不总是一致的。本文认为，在信息技术影响下，竞争景框发生了四个方面不同的变化：细分景框、产业景框和纵向景框三个方面是缩小的，地理景框是扩大的。

论经济一体化下的科技产业化立法

在全球经济一体化之下,中国科技产业化的发展,需要立足WTO规则,及时作出立法应对,迎接时代的挑战。科技产业化的发展,是产、学、研一体化的发展,要通过立法支持政府财政对非盈利性的科研院所的补贴,要在立法上加强对自主知识产权和商业秘密的保护。我国科技产业化的发展,需要反垄断立法的支持。WTO规则的扩展,包括环境保护议题,需要规则先行,完善立法,推进科技产业化的可持续发展。

Developing Technological Stance: Children's Learning in Technology Education

Following a review of current research in children's learning in technology education, and an examination of the kinds of knowledge demanded in contemporary technology education programs in elementary schools, I argue that what is needed in early technology education programs is the scaffolding of what I am calling technological stance. This construct acknowledges the socio-cultural character of technology as a human endeavor. In contrast to programs which are oriented to application of conceptual and procedural knowledge or to programs in which knowledge is generated through interpretation of interactions with materials and tools, programs which support technological stance position learners as critical inquirers into both tool-related and discursive practices of technology.
