Koreatown and Korean Small Firms in Los Angeles: Locating in the Ethnic Neighborhoods*

The locations of Korean firms in Los Angeles reflect spatial segmentation in markets and the provision of labor, in that the ethnic neighborhoods facilitate positive business environments for ethnic small firms. While Korean small businesses serve both community needs and broader local markets, firm locations are closely associated with the residential patterns of some ethnic populations. To address the specificity of firm locations, this paper examines Koreatown using historical sources and recent property development, identifies changes in the locational patterns of Korean firms between 1975 and 1986, and analyzes relationships between business density and density of ethnic populations for zip code areas. The findings of this study indicate that both the development of Koreatown and the presence of ethnic neighborhoods are important influences on the location of Korean businesses.     

湖南矿产资源形势分析与对策研究

湖南省不少矿产按地均资源占有量,高于全国平均水平,是国内矿产资源丰富和矿产最多的省份之一。从湖南的自然条件、经济条件、区位优势、资源地位、发展水平等方面分析,利用丰富的矿产资源发展湖南经济不失为一条重要的途径。要获取资源开发的总体效益和最佳效益的关键,是实现勘查、开采、加工三位一体化,发展多种形式,多层次的开发网络,面向国内、国外两大市场,加强资源综合利用、综合治理,才能把矿产資源优势转化为经济优势。     

Migrants, markets and multinationals: competition among world cities for the highly skilled

Urban areas compete with one another for people, goods, capital, ideas and other inputs of economic activity. Under the rubric of globalization, instead of only maintaining or improving the initial stock of assets in a city, the power of a place to attract outside flows of economic activity from elsewhere is increasingly important to economic development. Similarly, global or world cities are characterized as the command and control points through which these global economic flows operate. In response to the heightened mobility of highly-skilled labor across national borders, research has begun to examine the role of international human capital as an economic flow. This paper will examine the role of places in determining where the highly-skilled go in the global economy by viewing global city command and control functions as requiring unique labor flows. By reviewing the evidence found in the literature, we can better understand the potential for urban areas to compete for highly-skilled labor in the global economy. Known indicators of place attractiveness are assessed to examine the relationship between the economic trajectories of cities and their labor requirements. Cities are situated between firms and states as the key place-based actors which influence the mobility of highly-skilled labor. Finally, the paper also examines measurement issues and methodological problems in creating indices of world cities as well as explores possibilities for new research.     

上海城市功能的转型:从全球生产系统角度的透视

本文首先回顾了价值链与全球生产系统的研究进展，结合跨国公司最新发展趋势对全球生产系统特征进行了总结；其次以改革开放以来上海对外贸易结构的改变，描述了90年代以来上海在全球生产系统分工中的变化，认为出口产品结构的转型并没有真正改变上海在国际劳动分工中处于低端环节的地位；最后就上海建设世界城市的差距与优势进行了总结，提出全球化发展的外部力量和地方化响应的内部力量将是上海发展世界城市的两个重要驱动力。

Residential Mobility and Urban Restructuring under Market Transition: A Study of Guangzhou,China

Residential mobility can be conceptualized as an outcome of a choice process exercised under complex institutional and personal constraints. China's rather unique pattern of housing market segmentation under market transition impinges directly on residential location and relocation. Drawing upon data from a sample survey, this paper analyzes the pattern of residential moves resulting from commodity housing construction in a major Chinese city, Guangzhou. Most moves are of short distance, although the general direction is towards the urban periphery. Danweis and the municipal housing bureau, rather than the market per se, are the primary driving forces behind suburbanization in China today.     

天然碱和天然小苏打资源及开发动态

天然碱和天然小苏打是碳酸钠和碳酸氢钠的天然资源 ,即碳酸钠和碳酸氢钠的混合物(Ｎａ2 ＣＯ3·ＮａＨＣＯ3·2Ｈ2 Ｏ) ;而天然小苏打的分子式为ＮａＨＣＯ3。两种矿物都形成于非海相蒸发矿床。现代碱湖中还常见含水苏打 (Ｎａ2 ＣＯ3·1 0Ｈ2 Ｏ) ,又称泡碱 ,及水碱 (Ｎａ2 ＣＯ3·Ｈ2 Ｏ)等碳酸盐矿物。天然碱和天然小苏打主要用于加工成纯碱Ｎａ2 ＣＯ3,纯碱的主要市场应用集中于玻璃、化学制品和去垢剂。在资源和生产方面 ,由于天然碱和天然小苏打的经济资源完全受到地质成矿条件的限制 ,故而目前的生产局限于美国、南部非洲和中国。在…
