Multinational Companies,Technology Spillovers and Plant Survival*

How does the presence of multinational companies affect plant survival in the host country? We postulate that multinational companies can impact positively on plant survival through technology spillovers. We examine the nature of the effect of multinationals using a Cox proportional hazard model, which we estimate using plant‐level data for Irish manufacturing industries. Our results show that the presence of multinationals has a life‐enhancing effect only on indigenous plants in high‐tech industries, suggesting the presence of technology spillovers. In contrast, multinationals compete with each other in low‐tech sectors in the host country.     

The Essential Features of Technology and Technology Education: A Conceptual Framework for the Development of OBE (Outcomes Based Education) Related Programmes in Technology Education

It appears that programme development in technology education is emerging from an atheoretical perspective. This could be attributed to the absence/neglect of conceptual frameworks (philosophical underpinning) in the development of programmes in technology education. This article explores the role of the content dimension of the 'essential features' of technology and technology education in OBE (Outcomes Based Education) related programme development. An instructional programme was developed using criteria derived from the essential features of technology and technology education. In order to gauge learners' experience, in relation to these essential features, a qualitative case study involving 20 learners was undertaken at a College of Education. Engagement with theprogramme proved to be an empowering experience for the learners who had hitherto not had the opportunity to experience a formal programme in technology education. Although it could not be proved conclusively that cognitive development had occurred, positive inter-dependence,shared responsibility, social skills and enhanced learning were evident. The study has shown that criteria derived from the 'essential features' of technology and technology education could serve as a reliable yardstick to measure the extent of learning in relation to these essential features

The mean-variance investment problem in a constrained financial market

This paper extends the mean-variance analysis and the two-fund separation theorem to a market with some constraints, such as, the incompleteness, prohibition of short-selling, and partial information, with stochastic interest rate, and with stochastic volatility for risky assets. By maximizing a quadratic utility of terminal wealth, we show that the efficient frontier for the problem is a straight line in the mean-standard-deviation diagram. The quadratic utility function exhibits mean-variance efficiency. Our results apply to portfolios of claims in a single period, multiperiod, and continuous time.     

安徽区域科技基础条件平台建设面临的问题与对策探讨

区域科技基础条件平台建设是一项复杂的系统工程,建设工作分为基础性工作和特色性工作的提法有助于地方政府分析条件平台建设的重点和难点.科技条件平台的核心功能之一是以科技资源共建共享的方式向社会提供共性技术尤其是产业共性技术.地方政府解决科技资源供给和需求之间的矛盾的关键在于对共性技术范围进行界定以及确定如何供给共性技术.     

Static and dynamic efficiency of pollution control strategies

A great deal of the economic literature on pollution control strategies concentrates on the efficiency of environmental policy instruments. Most analytical studies in this field show that market instruments are more efficient with respect to the cost of pollution abatement of a given number of polluters than non-market instruments. According to several analytical studies, market instruments should also be more efficient with respect to innovation in pollution abatement equipment than non-market instruments. In the empirical literature a great number of case studies exist with estimations of the savings of abatement costs of market instruments in a situation without technological progress. Empirical studies about the impact of environmental policy market instruments on the abatement costs in situations with technological progress are lacking.The purpose of this paper is to fill this gap. The paper deals with an empirical estimation of abatement costs for the emission of SO₂ of coal-fired electricity units in the Netherlands from 1985 to 2000. First, the working of market instruments and non-market instruments (the existing environmental policy of the Dutch government) is simulated in a static situation. Second, we analyse the learning effects of flue gas desulphurization. The efficiency advantage of market instruments turns out to be larger in a situation of technological progress than in a static situation.     

交易费用与企业技术创新战略决策

对企业技术创新战略决策进行了两阶段分析，并采用交易费用理论对创新企业技术创新来源决策进行了分析，认为企业内部技术创新是企业吸收外部技术的基础，大部分企业技术创新将走自主创新与引进创新相结合的道路。     

相互制农业保险在我国的困境及适用性

相互制保险在农业保险领域有着明显的优势。然而,相互制保险管理制度上的缺陷及其与农业保险的矛盾制约着相互制农业保险的发展。目前,在我国合作意识不强、农村合作经济组织发育不健全的情况下,开展相互制农业保险还有一定困难。因此,要开展相互制农业保险,必须选择合适的范围和地区,并对相互制保险进行制度创新,为相互制农业保险提供财政补贴,建立再保险机制,加强引导,减少行政干预。

大学生人文素质的疏离与重建

人类创造的全部文化 ,包括科技和人文两部分。他们相辅相成 ,共同促进人类的发展与进步。可如今高等教育的现实却是 ,科学技术日益受到崇拜 ,而人文素质教育则逐渐疏离。在更加强调“以德治国”的今天 ,大学教育不应是科技与人文的分离 ,而应是二者的渐趋融合 ,正确认识科学技术的作用与限度 ,关注和营造人情化的生活世界
