THE WELFARE ASPECTS OF SPATIAL PRICING POLICIES RECONSIDERED FOR A MONOPOLY CASE*

ABSTRACT. We reexamine the price structures and their welfare implications in three pricing regimes (mill, uniform and discriminatory) for a monopoly. We show that spatial price discrimination could provide the highest social welfare and, when consumers tastes are heterogeneous enough, also the highest consumer surplus. The superiority of spatial price discrimination is partially due to the larger output produced and partially due to differential treatment for consumers with heterogeneous tastes.     

GENERAL EQUILIBRIUM ANALYSIS OF URBAN SPATIAL STRUCTURE. THE PORT-CITY MODEL RECONSIDERED*

In this paper, I consider a general equilibrium urban spatial structure in the setting of a port city by adopting Cobb-Douglas type functional forms for production and utility functions. Unlike previous port-city models, this one can generate four land-use patterns, that is, (1) monocentric, (2) completely integrated, (3) partially integrated (with integration at the center), and (4) partially integrated (with integration at the urban fringe) land-use patterns, and the last pattern suggests a new explanation of suburbanization of employment. The existence and uniqueness of each land-use pattern is proven in a simple constructive way.     

商品邮购(电话购物)的空间扩散与消费者抉择

信息通信技术在商品流通中的重要作用日渐明显,并且展现着进一步加强的趋势。电话(视)购物是当今已经"漫射"开来的普通电信在商业活动中应用的一个事实,可能对现存的地区性传统零售集团产生决定性影响-补充与替代共存。本文考查了国外邮(电)购的经验,并与我们在石家庄样区开展的调查工作进行了对比。最后我们对邮(电)购相关的区域规划问题进行了探讨,认为其与电话购物之电信服务方式的空间扩散相互影响。本文也旨在揭示这种零售方式是如何改善边远地区的购物条件的。     

流动性视角下中国流行菜系的空间扩散格局及其文化地理逻辑

流动性的增强不但意味着人口、信息、资金流动强度增加,也意味着流动范围的扩大。在此背景下,以稳定的人口构成为基础的传统地域饮食文化区的边界也开始发生变化。同时,流动性也使多元地方饮食文化在空间扩散的基础上展开了互动与交融。本研究将除港澳台地区以外的中国全域作为研究区域,基于海量餐饮服务设施POI数据,运用核密度分析方法分析中国目前的流行菜系空间扩散格局并描述其特征,并从流动性视角阐释其形成与扩散的文化地理逻辑。研究发现,中国现流行的菜系主要包括川菜、湘菜、粤菜、东北菜、徽菜、云贵菜、西北菜、鲁菜;中国流行菜系的空间扩散格局具有差异明显、多中心发展的特点。其中,川菜、湘菜、粤菜数量多分布广;鲁菜、徽菜分布集中,扩散较少;东北菜、云贵菜、西北菜数量较少但分布范围广。这种流行菜系空间扩散格局背后的文化地理逻辑与流动性密不可分,人口、资金等的流动促使地方饮食文化在空间内扩散,同时也带来了地方饮食文化间的交融互构。     

THE HOMERIC TOPOGRAPHY OF THE TROJAN PLAIN RECONSIDERED

Summary. Homeric passages bearing on the location of the Achaean camp at Troy are re-examined in the light of new scientific data on the time-scale for the alluviation of the Trojan plain. The new data confirm the accuracy of Strabo's account of the plain, and in particular of the shore-line having come close to the Hisarlik site ( Novum Ilium ) in Hellenistic times. In the era of Troy VI/VII, c. 3,250 years BP, the shore-line appears to have run west by south of the site, and a broad marine embayment lay between the city and the Sigeum ridge. It is therefore no longer possible to accept the received view (deriving from Schliemann and Leaf) that the Achaean camp was sited on the present shore-line by the Hellespont. A new site is proposed for the camp on the lower slopes of the Sigeum ridge about four miles west of Hisarlik. It is argued that the indications in the Iliad are not inconsistent with such a siting, and in fact suit it better than the received view. This is shown with regard to the course of the Scamander, evidently pictured by Homer as running between camp and city, and also with respect to the general axis of the fighting on the plain, which is indicated to lie in an east-west rather than a north-south direction. The Besika Bay site, first proposed in 1912, is rejected as inconsistent with the Homeric data and unsatisfactory in itself.     

THE METALLURGY OF THE NAHAL MISHMAR HOARD RECONSIDERED

The Nahal Mishmar hoard, found in a cave in the Judean Desert in 1961, is a key find for the study of Chalcolithic metallurgy in Israel and the Levant. Recent analyses of Chalcolithic metalwork from sites such as Shiqmim in Israel raised doubts about the validity of published analyses from the hoard. Accordingly a programme of re-analysis was established using atomic absorption spectrometry and electron probe microanalysis. The new analyses confirmed the doubts and showed that the metallurgy of Nahal Mishmar was the same as that at the other sites. The alloys used for the cast products in the hoard were generally ternary arsenic-antimony copper alloys with up to 20% alloy content; less common were compositions with arsenic and nickel. The unusual metallography of these alloys is described. Some suggestions are offered as to the mode of manufacture of the alloys.     

西北地区县域数字金融发展的空间扩散规律与内在机制研究

本文基于2014—2018年数字普惠金融指数,从金融地理学视角考察西北县域数字金融空间扩散规律及其内在机制。研究发现：第一,西北县域数字金融发展呈现从低低集聚向高高集聚区间集中的趋势,扩散现象明显。第二,信息技术的运用是数字金融发展与扩散的内生动力,但其有效发挥受传统金融地理结构影响。其会率先在传统金融机构分布较密集的地区发展,并显著体现在覆盖广度和使用深度两个维度。第三,基础设施水平和教育水平是有效的推动力,有助于数字金融向欠发达县域扩散。第四,从细分维度看,基础设施的作用仅体现在覆盖广度上,教育水平的推动作用则表现在覆盖广度与使用深度两个层面,但目前还无法有效促进数字化程度的扩散。     

THE HOPE HERAKLES RECONSIDERED

Summary. The Hope Herakles, hitherto thought to be a Roman copy of a statue by Skopas, is here shown to be a pastiche. The head is tentatively recognised as a classicising portrait, while the body type, having come down to us in a variety of reproductions carrying a different head, is associated with the Argive School of the late 5th c BC. A dating of the latter's prototype close to the plague of 429 as well as the Attic provenance of some of the copies suggest a possible connection with Hageladas'Herakles Alexikakos at Melite.     

运用空间自相关分析集聚经济类型的地理格局

集聚经济的类型决定着区域经济的发展方向。传统的度量指标是基尼系数、Ellison-Glaeser指数等,但这类指标却没有考虑相邻地区间经济的相互影响。据此,本文提出用空间自相关方法,衡量区域的集聚经济水平,并且利用2002年江苏省县级工业数据,实证分析和探讨江苏省城市化和地方化集聚经济的地理格局。     

THE ROMAN CHURCH AT SILCHESTER RECONSIDERED

Summary. The historical development of the current interpretation of the Silchester church is reviewed, and shown to reflect the prior notion that it was a church, to the detriment of other possible interpretations of its use. The interpretation as a church presents several problems, mainly to do with the probable date of construction of the building, in the late third or early fourth century, and its abandonment, in about the second third of the fourth century. Romano-Celtic temple architecture seems to have had some influence on the design of the building, but on balance, the best possibility for its use was for an eastern cult.     

THE EURASIAN ORIGINS OF EMPTY TIME AND SPACE: MODERNITY AS TEMPORALITY RECONSIDERED

Understood as a form of temporality, modernity is seen as consisting of empty time and space. However, careful examination of the origins of modern notions of empty time and space suggest they arose from background assumptions in wide use across Eurasia in the early modern period, and also that they arose prior to, and independent of, the emergence of the modern nation‐state. Here, various Eurasian versions of astronomy and philology are examined to show that they relied on such background assumptions and could therefore be readily translated and shared across the boundaries separating quite different cosmologies.     

SPATIAL DEPENDENCY OF SEGREGATION INDICES

A few researchers have mentioned the scale sensitivity of segregation index, D. In this paper, I discuss analytically and empirically why using large enumeration areal units usually results in low segregation measures, and using small areal units produces relatively high segregation measures. The discussion is also applicable to the multi-group variant of D. A major finding is that if people of the same ethnic groups are positively spatially auto-correlated, increasing the size of areal units of analysis may not lower D initially, because only people of the same group are added. But enlarging the areal units subsequently may include population of other ethnic groups, and therefore could lower D. However, if the boundaries of the larger enumeration units are drawn to include only population of the same group, then D will not change significantly. Both the spatial autocorrelation of ethnic group population and zonal pattern are critical factors in determining the scale sensitivity of D.
