In the 1950s, the Ministry of Health, supported by interested groups outside government, recognised the political importance of productive efficiency. For leadership, organisational models and techniques the Ministry looked to the movement for industrial productivity. The NHS was receptive, but private-sector approaches were modified and dampened as they were imported. NHS management was to be the provider of technical expertise, but the deployment of this expertise was limited by clinical autonomy and de-coupling from financial incentives. This article casts new light on the history of productivity policy, NHS management and the moving frontier between state and civil society. 相似文献

This paper explores the reasons why cities are often major centres of innovation, even in some less favoured regions and countries. It starts with an anatomization of the dominant factors that explain why key less favoured settings developed 'new economy' clusters through institutional interaction with Silicon Valley. The analysis concludes that public research resources and private commercialization funding are central, supported by a wide array of private but few public innovation support services. It then examines a number of cases from cities in less favoured regions and countries where innovation has occurred. The conclusions are that the research-venture capital model is present and explains innovation in each case. However, in some cases public venture capital has to substitute for private due to market failure, or a phenomenon termed 'Silicon Valley Offshore' has been induced. Cities are innovative where they concentrate the desired scientific and investment knowledge capabilities. 相似文献
