This article discuss in a tentative way what determines the effect of technological discontinuities on the competitive position. of companies within an industry. Three cases of technological change are anahzed: the change from manual to romputer numericalb controlled metal cutting machine tools, the change from stand-alone machine tools to flexible manufacturing systems; and the change from non-cellular to cellular mobile telephony It is argued that the character of technological discontinuity affects market shares, by altering the barriers to entry and mobility, and by being more or less in accordance with the different firms' vision about the future, implying variations in the time needed to detect and accept the new threat or opportunity. A technological discontinuity that includes a new threat or opportunig. A technological discontinuip that involues a new generic technology which substitutes for rather than adds to the previous technology base is seen as being most disruptive. The time actualb available for detecting the need to change and to act is limited by the market growth of the new product (the 'speed of diffusion between users). The faster the difficulties is, therefore diffusion is the greater are the possinbilities that early movers will fain intial advantages. Furthermore, the faster the diffusion is the greater are the possibilities that early movers will build sustanable, volume-related entry and mobility barries.  相似文献

Interactive television has arrived, thanks to substantial technology investments that have been made by Sky and others. It is growing in importance as innovative interactive applications are developed for broadcast programmes (eg the BBCi service and Big Brother), and for advertising — and will develop further when broadband deployment gets to critical mass. Readers should not expect a television-variant of the world wide web, however. This was tried during 2000–2002 in the form of web look-alike, interactive ‘walled garden’ sites, and failed to attract critical mass footfall. The model has evolved and now revolves around interactive content synchronised with broadcast, which offers financial services companies an interesting new way to increase awareness and to differentiate the service presentation. Furthermore, over the next ten years, broadband is expected to usher in a new era of personalised television — in which specialised broadcasts (such as personal pensions advice programmes) can be made available on demand. The observations in this paper are mainly drawn from the UK, where digital television penetration is high; the lessons can be applied more broadly, however, and are relevant to any organisation thinking of promoting its service through entertainment channels.  相似文献

Encouraged by a highly expansionary economic policy, the global economy is enjoying a rapid upturn. Utilisation of capacity is high in many sectors, particularly in the growth centres of the USA and East Asia, where China leads the field. With inflationary risks on the increase, most countries are now shifting the focus of economic policy. Fiscal policy in particular can be expected to provide little in the way of further stimulus. In addition, there has been a turnaround in interest rates in many countries. Yet how quickly can the monetary reins be tightened without jeopardising growth or endangering price stability?  相似文献

In 1996 the Heavily Indebted Poor Countries (HIPC) Initiative was launched by the Bretton Woods institutions to reduce the external debt burden of low-income countries (LICs) to sustainable levels in a reasonably short period of time because debt constitutes an obstacle to sustainable economic growth and poverty reduction. In some HIPCs, however, debt sustainability has been in danger despite debt relief under the HIPC Initiative. Debt relief is a necessary but not a sufficient condition for development. It can do no more than play a catalytic role. The question, then, is how to achieve debt sustainability beyond the HIPC Initiative.  相似文献
