Trade and Industry Policy   总被引:1,自引:0,他引:1  
This article consists of a review of changes in trade and industry policy, along with discussions of the determinants of change and the major problem areas. Policy between 1965 and 1985 is summarised, and the growth of unemployment in the 1970s is suggested as a key determinant of change. Higher protection in certain industries, and moves to more quantitative methods ot protection can be related to unemployment, in Australia as in other countries. Theory and empirical evidence suggest that protection is likely to prove ineffective in reducing unemployment. The reliance on protection in particular cases is ascribed to a wish by governments to preserve specific jobs, not to increase overall employment. Policy can have a role in facilitating or restricting structural change which can arise from several sources, such as changing trade patterns and preferences. The devices of policy are considered briefly to determine whether they are likely to facilitate change or not. It is concluded that they often provide incentives to avoid change. The scale problem is considered, and it is suggested that the cost of protection could be high in industries subject to significant scale economies. Scale and adjustments are considered in the light of two industries, motor vehicles and whitegoods, and the role of industry plans is examined. The actuality of trade and industry policy often differs from announced intentions, and this ambiguity can give rise to uncertainty which itself has a cost.  相似文献

This essay offers a detailed review of the literature on the relationship between technology and science. It is in two parts. Part I begins by describing science and technology, and the differences between them. It then discusses the commonly-held technology-as-applied-science (TAS) view; the origins of this view, the support for it, and the strong historical and philosophical challenges to it, beginning more than half a century ago, are explored. The development of the steam engine is then offered as a brief case study to illustrate that science-technology relations are more complex than implied by the TAS view. Part I concludes with a consideration of ontological arguments supporting the reverse view, namely that technology is often a necessary precursor to science.Part II, to be published in a following issue, explores some of the consequences of the TAS view. One consequence is that it has generated a story-line in which scientific ideas are emphasised and other factors necessary for technological innovation have been down-played. Another consequence is that, even in cases where technology does apply scientific knowledge, the process of application is often considered obvious; the difficulties of translating ideas into artefacts may not be appreciated. The essay argues for the telling of a more complex story of science-technology relations, one which recognises their historical independence in the past, and their mutual, two-way interaction in many modern fields of endeavour. It concludes with a consideration of some economic and educational implications.  相似文献
