Specialization and Productivity Performance in Low-, Medium-, and High-Tech Manufacturing Industries
This study makes us of the OECD Structural Analysis industrial database (STAN) to investigate patterns of industry specialization as measured by the country's share of total industry production for 14 OECD countries over the period 1970 to 1993. I find that these industrialized countries tended to specialize manufacturing production in very different industries and most countries retained their specialization over the period from 1970 to 1993.
In allusion to the particularity of site selection for underground maintenance equipment warehouse in modern war,a fuzzy optimization site selection method based on region determination is proposed in this paper.First,the region of the optimization warehouse site was established with the differential method.Then,based on many influencing factors,the site selection assessment index system was established,and weight was defined by AHP.Finally,through the optimization selection with multilevel fuzzy comprehensive evaluation,the optimum site selection scheme was determined.It is proved by practice that the proposed method can solve the problem of much previous workload for general site selection.
