In this note, I present a method to estimate the desired distance between medical facilities. The survival rate of patients improves when the facility is larger, however larger facilities result in a longer driving distance to the facility which decreases the survival rate. I identify the desired distance between facilities for which the survival rate is maximized.  相似文献

This note considers Blair, Kaserman, and Romano's conclusion (1989) that the only optimal solution in the case of bilateral monopoly is the joint profit maximization solution and examines the pattern of industrial location under joint profit maximization.  相似文献

This paper examines the theoretical implications of quantity-discounted transportation rates on the optimum location decision of the firm. It shows that the linearly homogeneous or homothetic production function is not a sufficient condition for the independence between the optimum location and the output level, unless (i) the elasticities of transportation rates with respect to quantity shipped are constant and identical, and (ii) the ratios of marginal products 60 the marginal transportation costs are equal for each input.  相似文献

国内外农村居民点区位研究评述   总被引:22,自引:1,他引:22  
李君  李小建 《人文地理》2008,23(4):23-27
随着人类经济社会的发展,居民点的外在特征和空间结构也在不断的演化与变迁,居住地点的选址和布局最能反映出人类活动与地理环境之间的相互影响与作用机制。目前国内外在城市居住区位研究方面已经形成大量研究成果,相比之下,农村居民点相关研究还存在一定滞后。文章从居民点区位影响因素、区位演变、居民点分布和等级结构四方面对国外相关研究进行了评述,梳理了国内农村居民点区位研究的相关内容,在此基础上对存在的问题进行了讨论和总结,并对今后研究内容进行了展望。  相似文献

From the 17th to the 12th Century B.C. the Hittite Kingdom was one of the most notable powers in the Near East. It ranged over a vast geographical area dominating the surrounding cities and smaller states. Throughout this time the Hittites consistently developed their political system thereby ascending to the level of an empire. From sources pertaining to this era, it can be ascertained that already in the early stages, when the borders were not as extended, the Hittite Kingdom adopted the tradition of sending the king's sons and princes to the newly conquered regions and significant cities.  相似文献
