Gregory Tassey 《Research Policy》2005,34(3):287-303
Technology and the process that produces it, research and development (R&D), are typically characterized as homogeneous entities. In reality, the typical industrial technology is composed of three elements: a generic technology base, supporting infratechnologies, and proprietary market applications (innovations). The first two have public good characteristics, and therefore, explicitly modeling them is essential for public policy purposes. The fundamental relationships among these elements require a technology production function that captures the supporting roles of the public good elements in creating proprietary applied technology. These critical quasi-public technology goods are supplied to a significant extent by exogenous (external) sources: central corporate research labs, government labs, and increasingly, universities. The expanding university role beyond basic research complicates the structure and functioning of the national R&D establishment and increases the need for a more accurate model of technological change to better inform R&D policy.Moreover, in assessing the resulting applied technology's impact on economic growth, both the general and partial equilibrium literatures enter the technology variable into a production function with the common “production” assets (physical capital and labor). Such models obscure an important distinction between technology and these production assets—namely, the fact that technology is primarily a “demand-shifting” asset. As such, its role is correctly specified only when combined with the other major demand-shifting asset, marketing. Allocations to these two assets vary across competing firms implying a spatial model of competition, while still providing traceability to the exogenous sources of public good technology elements, such as universities. 相似文献

The South African National Integrated Early Childhood Development Policy was approved by the South African Cabinet in 2015. Given capacity and financial constraints, all services outlined cannot be implemented in a single step. Priorities must be set. We examine the budget implications (total cost and cost per child) and benefits of the four largest components of the Policy: interventions to improve pregnancy outcomes; home visits for at-risk mothers of children under 2 years of age; community-based playgroups for mothers and children, and center-based early childhood development services. Further, we identify which services are based on the strongest evidence, the value-based trade-offs that characterise the prioritising decisions, and which logistical factors favour alternative orderings of services. The interventions to improve pregnancy outcomes are low cost, based on sound evidence and would make use of the established healthcare infrastructure. Home visits for at-risk mothers are associated with improved development for targeted children and consequential benefits for caregivers and broader society. Playgroups are a promising low-cost intervention, but further evidence is required to determine their effectiveness. Centre-based services are expensive and generate smaller developmental returns, but provide childcare. The results highlight the value judgements required to determine the appropriate sequencing of interventions. 相似文献

文章介绍了英国高等教育财政拨款多元化和政府影响力不断削弱的变革趋势,继而从理论和实践两个层面探索了这一变革的原因.从实践层面看,全球竞争的压力和高等教育规模的扩大使高等教育财政面临挑战和困境;从理论层面看,根据三角螺旋模型,在满足更广泛的经济和社会需求的背景下,对高等教育的目的和价值应有新的理解.文章接下来从国际比较的观点阐述了2008年金融危机对英国高等教育投资的影响,在此基础上讨论了英国政府和大学的对策及未来的战略重点策略. 相似文献

民营资本的加入是我国垄断性行业改革的必由之路 总被引:1,自引:0,他引:1
从我国加入WTO,以及垄断行业面临的现实矛盾看,采取多种措施,对民营资本开放垄断行业,深化垄断行业改革,放宽市场准入,实现投资主体和产权多元化是我国深化改革的要求。同时应认真解决好民营资本加入垄断性行业后有关投融资体制改革、提高政府承诺的可信性以及政策的稳定性、如何客观地看待地方政府的参与等重点问题。 相似文献
