Recent theoretical and empirical analysis in the field of economic organization has focused almost exclusively on identifying organizational practices and complementarities between such practices, without regard for the type of activity in question. However, organizational theory suggests that more knowledge-intensive production activities often involve higher degrees of strategic uncertainty for firms and performance ambiguity in relation to individual employees. Therefore, the 'organic' or 'clan' form of organization - involving the application of 'new' HRM practices - is expected to perform better within knowledge-intensive sectors of the economy, as compared to other sectors. A sample of 726 Danish firms with more than 50 employees in manufacturing and private services is studied. The results show that HRM practices are more effective in influencing innovation performance when applied together, as compared with situations in which individual practices are applied alone. In other words, organizational complementarities obtain. Moreover, the application of complementary HRM practices is more effective for firms in knowledge-intensive industries ('high' and 'medium' knowledge-intensive industries).  相似文献

This study shows that firms in the pharmaceutical industry experience decreasing returns to scale in R & D as the level of R & D expenditures rises. The paper presents the results of our study of the innovative output of 16 pharmaceutical firms over a 19 year period. Given the strong correlation between R & D budgets and firm size, our study suggests the wave of mergers in the industry may yield less innovative productivity than managers expect.  相似文献

面对不断飙升的房价,从理论界到政策层面对其原因都有不同的解读,但从实践结果来看对房价的治理并不理想。本文在综合分析理论研究与国家调控政策的基础上,认为创新措施采取网络型的政府市场供给模式是解决房价过快上涨的有效途径。文章着重对这一模式进行了分析,并认为此举对缓解供需矛盾、解决市场的信息不对称、市场操控、改变预期、稳定房价等都有非常重要的作用。  相似文献

A wide range of intractable problems such as polluting emissions, noise, accidents, resource depletion, and inaccessibility of amenities are associated with the current transport regime. Given the slow movement towards a more sustainable mobility system, more radical, systemic innovation - a ‘transition’ - is required. Broadly speaking, this may be achieved via three routes: technological change, modal shift, and reduced travel demand. Drawing on concepts from the transitions literature (e.g., [Geels, F.W.: Technological Transitions and System Innovations: A Co-evolutionary and Socio-Technical Analysis, Edward Elgar, Cheltenham, 2005.]), we conceptualise each of these routes as a bundle of niche activities within an Area of Innovation, deviating to differing degrees from the current mobility ‘regime’. We present empirical evidence and indications of ongoing development of niches in these three areas within the UK and Sweden, and explore processes of co-evolution, divergence and tension within and between niches. Findings indicate recent market penetration of novel transport technologies, more advanced than modal shift or demand management activities; however, different transport technologies are more successful in each country. We also identify examples of a close relationship between development of radical vehicle/fuel technologies and provision of mobility services; and information technology as a driver in all three areas of innovation. We conclude that future innovation in transport depends on diversity, hybridisation, and co-evolution of niches. Finally, policy implications are discussed.  相似文献

Technological proximity and the choice of cooperation partner   总被引:1,自引:0,他引:1  
This paper provides empirical tests of hypotheses of cooperative behavior provided by evolutionary approaches in the resource-based view of the firm. The influences of “technological proximity”, individual incentives to cooperate and managerial tools to the choice of research partner are analyzed. Using German patent data we can show the positive influence of those three determinants. The results of this paper confirm theories dealing with the path-dependency of research activities.   相似文献

We analyze industry equilibrium and incentive to compatibility when goods produced by different producers generate utility only when consumed as component parts of a system. We assume the presence of two systems, each composed of some basic component and a set of differentiated complementary products. The combination of complementarity between the two components of the system and of fixed costs in the production of the complementary product results in a form of network effect. We focus on the role played by the size of the fixed costs in the production of the complementary products in determining the size of this system effect and, by this means, the structure and types of equilibria that may be observed: monopolistic or duopolistic, symmetric or asymmetric. We also highlight the consequence of the same fixed costs for the private and social incentives to render the systems compatible.  相似文献
