This paper evaluates some of the key arguments underlying what is called here the local production network paradigm (LPNP). These are presented as three interlinked hypotheses that turn on the idea that firms competing in world markets need to accommodate continuous change by fostering product or process innovation. The definition of innovation used in this study is “the commercially successful exploitation of new technologies, ideas or methods through the introduction of new products or processes, or through the improvement of existing ones” (EC DG XIII, 1996, p. 54).
One conventionally described organizational response to this requirement to accommodate continuous innovation is to dis‐integrate firms and set up local production networks. Local production networks are defined in this study as “collaborative linkages between local firms and local factors of production”. Such networks are said to rely on local resources of various kinds to enable them to innovate on a continuous and incremental basis. As a result of such dependencies on local factors, and their interconnectedness with each other, the local production network (LPN) firms then become ‘embedded’ in their localities. Such networked economies have been variously described as new industrial districts, areas of flexible specialization, and innovative milieux.
The evidence presented to test these hypotheses is based on a case study of innovative, award‐winning firms in Hertfordshire. The findings show that although these firms do compete successfully in fast‐moving international markets, they do not rely much on local production networks, as defined here, to enable them to do so. The findings call into question the general applicability of the LPNP. Questions are raised particularly with respect to innovation in the important minority of highly innovative core metropolitan regions.
Innovation is argued to be an interactive process that is both driven by a steady supply of technological advances and stimulated by different types of consumer demand. In the case of the firms interviewed in Hertfordshire, most of their innovative projects were developed by the firms working individually, and in isolation, from other local businesses using high quality, knowledge, information, human resources and venture capital. At the same time, these firms were also pulled by demands from military, health and company consumers. Only in the case of the minority of innovations that were purchased in the first instance by private final consumers were local production networks of some significance. 相似文献

Following the 1745 rebellion, agrarian capitalism rapidly transformed subsistence practices in the Outer Hebrides. Landowners increased rents, enclosed common lands, and replaced crofters and cattle with sheep-ranges. Population growth, the demise of the kelp industry, and crop failures compounded the problems of the peasantry. Widespread emigration commenced in the 1770s and peaked in the 1850s, when entire communities were exiled to British North America—the so-called Highland Clearances. This article traces the development of agrarian capitalism on the Isle of South Uist, explores the agricultural improvements undertaken by successive landlords, and considers modes of resistance adopted by the island's population.相似文献
The Hohokam reached an apex of sociopolitical development between the twelfth and fifteenth centuries in the Sonoran Desert of North America. Hallmarks of the Hohokam tradition included red-on-buff pottery, large-scale canal irrigation agriculture, and monumental buildings, including ball courts, platform mounds, towers, and Great Houses. The development and elaboration of Hohokam society from their ceramic-producing predecessors during more than two millennia (ca. 1000 B.C. to A.D. 1450, or later) is a remarkable example of an arid land adaptation in the New World. The enigmatic collapse of Hohokam society took place shortly before European colonialists entered the North American Southwest in the mid–sixteenth century. Various agents (e.g., floods, disease, warfare) of this event are poorly understood and require additional study. So, too, does the degree of historical continuity between contemporary indigenous peoples and precontact archaeological cultures (e.g., Hohokam) in what is now Arizona and northern Mexico. 相似文献
Oxygen is a key parameter in the degradation of archaeological material, but little is known of its dynamics in situ. In this study, 10 optical oxygen sensors placed in a 2 m deep test pit in the cultural deposits at Bryggen in Bergen have monitored oxygen concentrations every half hour for more than a year. It is shown that there is a significant spatial and temporal variation in the oxygen concentration, which is correlated to measured soil characteristics, precipitation, soil water content and degradation of organic material. In these deposits oxygen typically occurs when the air content of the soil exceeds 10–15% vol, while oxygen dissolved in infiltrating rainwater is of less importance for the supply of oxygen in the unsaturated zone. 相似文献
Twenty‐six samples from domestic assemblages of 9th–12th century Córdoba were subjected to electron microprobe analysis. The results reveal two main compositional types. The first, encountered in 13 of the samples, seems to result from the combination of plant ashes with high‐impurity sand, and has some contemporary parallels from Syria and Egypt. The second type is a lead–soda–silica glass, encountered in a relatively high proportion of the glasses (11 of the 26 sampled), possibly formed by the addition of lead metal to existing glasses and with very few known parallels. These are among a very small number of results available to date on the chemical composition of glasses from medieval Spain, and the presence of a high proportion of lead–soda–silica glasses is particularly interesting, possibly indicating a technological practice unique to, or originating in, the western Muslim world. 相似文献
