基于可拓层次分析法的物流中心选址评价

首先依据物流中心选址的评价指标体系确立原则,建立了评价指标体系,然后利用可拓层次分析法（EAHP）对选择的最优策略进行研究,解决了在构建模型中对指标的模糊主观判断问题,以及在研究中判断矩阵不具有一致性的问题,使物流中心选址模型的最优策略更接近实际,通过对物流中心服务质量例证分析,取得了满意的结果。     

Location decisions: The role of uncertainty about consumer tastes

This paper analyzes to what extent firms make decisions about location based on uncertainty about consumer tastes. The model used in this analysis incorporates a linear city and quadratic consumer-transportation costs. In this framework, when firms choose locations, or in other words, choose the kind of product they are going to manufacture, they ignore the location, or real tastes, of their consumers. The existence of uncertainty raises the degree of product differentiation, because the anti-competitive effect that arises as distance from rivals increases counteracts the reduction in the degree of differentiation provided by the demand effect.

The International Division of Industries: Clustering and Comparative Advantage in a Multi-industry Model

We consider a model with a large number of industries and agglomeration forces which cause each industry to concentrate in a single country. We show that the division of industries between countries is not unique, and that identical countries might have different numbers of industries and different wages and real incomes. Countries may gain by using policy to grab a higher proportion of world industry. Bounds on the set of equilibrium divisions of industry are found and we show how, with Ricardian differences in technology, there are equilibria with industries locating in the country where they have a comparative disadvantage.

Patterns of Economic Development and the Formation of Clubs

This study investigates the sources of heterogeneity across a worldwide set of countries. Unspecified ex ante and unanticipated cultural (Protestant versus Catholic), geographical (continents), and institutional (OECD versus non-OECD) clubs emerge endogenously and naturally as homogeneous classes on the basis of their economic structure. The dynamics both within and across the identified groups of countries are consistent with multiple equilibrium-growth models proposed by, for instance, Azariadis and Drazen (1990), therefore strengthening the viability of the convergence club hypothesis. In particular, higher stages of development are, on average, non linearly associated with higher stages of growth.

黑龙江省发展优势产业的基本对策

利用黑龙江省各产业区位商值和影响力系数、感应度系数以及产业关联度系数等指标,采用综合评价方法中常用的指数构造方法,对优势产业进行综合分析得出:目前黑龙江省存在着总体产业优势地位不突出、经济效益不佳、技术进步投入不足等问题。应采取加快老工业基地改造、推进企业生产和组织结构升级、加大农业综合开发力度、大力发展第三产业等措施,以促进黑龙江省优势产业的持续发展。     

Risk and the strategy of foreign location choice in regulated industries

We argue that firms in regulated industries react to macroeconomic and policy risks in sharply different ways. While they seek to avoid countries with high levels of macroeconomic uncertainty, we predict that they find it more attractive to expand into countries characterized by governments with discretionary policymaking capacities so as to be able to negotiate favorable conditions of entry. We also argue that firms are heterogeneous in their attitudes toward risk. We predict that firms in which the state holds a partial equity stake exhibit a more tolerant attitude. We also expect that as firms accumulate foreign experience, they develop an aversion toward further foreign entries into politically unstable markets. Support for these predictions is provided by an analysis of the Latin American market entries of all listed Spanish firms in regulated industries between 1987 and 2000.
