对有效财务分析在实际工作中的探讨

基于对现行财务分析不足的研究,文章试图运用产业经济学、企业战略管理和现代公司财务理论,提出一个新的、对管理决策更为有效的财务分析模式。这一模式由5个相互关联的步骤构成,即对企业所处特定产业(或行业)的经济特征的分析、对企业战略的分析、正确理解和调整企业的财务报表、评估企业的盈利能力和风险、为管理决策提供相关的依据。     

Interregional Inequality Dynamics in Mexico

Abstract

This paper examines 60 years of regional income inequality dynamics across the states of Mexico. Drawing on recent developments in exploratory spatial data analysis (ESDA) we examine the role of spatial clustering and heterogeneity in the evolution of regional inequality. We pay particular attention to the choice of the regionalization scheme that has been applied in previous work and we suggest a number of new approaches to evaluate the sensitivity of inferential conclusions to this choice. We also investigate if temporal shifts in equality are reflected in the NAFTA era.

Dynamique de l'inégalité interrégionale au Mexique

Résumé la présente communication se penche sur la dynamique des inégalités régionales entre les revenus pendant 60 ans dans les états du Mexique. Sur la base de développements récents dans les analyses exploratoires des données spatiales (ESDA), nous examinons le rôle du groupage et de l'hétérogénéité spatiaux dans l’évolution des inégalités régionales, en nous penchant tout particulièrement sur le choix du plan de régionalisation appliqué à des travaux précédents, et en proposant un certain nombre de méthodes nouvelles pour évaluer la sensibilité de conclusions déductives sur ce choix. En outre, nous tentons d’établir si des changements temporels dans les inégalités sont reflétés dans l’ère de NAFTA.

Dinámica de la desigualdad interregional en Méjico

Extracto Este trabajo examina 60 años en la dinámica de la desigualdad regional de ingresos a través de los estados de Méjico. Haciendo uso de desarrollos recientes en el análisis exploratorio de datos espaciales (ESDA) examinamos la función del agrupamiento espacial y la heterogeneidad en la evolución de la desigualad regional. Prestamos particular atención a la elección del esquema de regionalización que se ha aplicado en trabajo anterior y sugerimos varios planteamientos nuevos para evaluar la sensibilidad de conclusiones inferenciales de esta elección. También investigamos si los cambios temporales en igualdad se reflejan en la era NAFTA (Tratado de Libre Comercio de América del Norte).

     

Practical Proposals for Specifying k-Nearest Neighbours Weights Matrices

Abstract

In this article, we introduce and evaluate testing procedures for specifying the number k of nearest neighbours in the weights matrix of a spatial econometric model. An increasing and a decreasing neighbours testing procedure are suggested. Kelejian's J-test for non-nested spatial models is used in the testing procedures. The testing procedures give formal justification for the choice of k, something which has been lacking in the classical spatial econometric literature. Simulations show that the testing procedures can be used in large samples to determine k. An empirical example involving house price data is provided.     

Traffic density,congestion externalities,and urbanization in China

ABSTRACT

Although there is an abundant regional literature analyzing traffic congestion, only a few studies have explored extending such analysis with spatial effects. This study uses a dynamic spatial Durbin model and city-level panel data for the period 2003–14 to investigate the spatial spillover effects of traffic congestion on urbanization in China. The results show that there is an inverted ‘U’-shaped relationship between urbanization and traffic density in local and neighbouring cities, and congestion effects have appeared. In the short and long run, the spatial effects of traffic congestion have become an important force restricting the effective promotion of urbanization in China.

Raising the bar (5)

Raising the bar (5). Spatial Economic Analysis. This editorial summarizes and comments on the papers published in this issue 12(1) so as to raise the bar in applied spatial economic research and highlight new trends. The first paper examines the impact of the level of education on the decision to migrate and finds that it is approximately twice as large if both variables are modelled simultaneously. The second paper is one of the first papers to introduce a spatial component to models of international environmental agreements and to develop an exciting overlap with New Economic Geography. The third paper provides a tool, applied to Beijing, with which urban economic planners can investigate the role of variation and selection mechanisms in cluster development and identify possible paths of growth. The fourth paper contributes to the existing literature on retail geography by examining the role of consumption possibilities as an urban amenity. The fifth paper develops a Bayesian estimator of a linear regression model with spatial lags among the dependent variable, the explanatory variables and the disturbances. Finally, the sixth paper develops a semi-parametric generalized method of moments (GMM) estimator for a spatial autoregressive model with space-varying coefficients of the explanatory variables and a spatial autoregressive coefficient common to all units.     

Raising the bar (6)

Raising the bar (6). Spatial Economic Analysis. This editorial summarizes and comments on the papers published in issue 12(4) so as to raise the bar in applied spatial economic research and highlight new trends. The first paper addresses the question of whether ‘jobs follow people’ or ‘people follow jobs’. The second paper develops a new methodology to determine functional regions. The third paper is a major contribution to the growing literature on new modelling approaches and applications of disaster impact models. The fourth paper focuses on the costs and benefits of higher education. The fifth paper develops a two-step procedure to identify endogenously spatial regimes in the first step using geographically weighted regression, and to account for spatial dependence in the second step. Finally, the sixth paper estimates a dynamic spatial panel data model to explain house prices and to show that restricted housing supply in the city of Cambridge, UK, has some undesirable labour market effects.

美国行政中心空间与规模特征及其成因研究

行政中心是行政区划的基本要素之一,行政中心尽量靠近地理中心对行政管理和促进区域发展平衡有积极的理论和现实意义。文章提出了行政中心与地理中心偏差的计算公式,运用空间统计分析方法结合Ar-cGIS软件,以美国为例,分析了美国县治与地理中心地理偏差的空间分布和数据特征以及州府与州最大城市的人口规模关系特征,总结了产生以上特征的自然、历史和政治上的原因,并运用空间可视化方法直观地显示分析结果。分析结果表明：①美国的县治普遍比较接近地理中心,其接近程度有由东部向西部递减的趋势且存在一定的空间集聚;②州府大多数并非州最大城市,人口较少。最后从行政中心区位选择和区域发展平衡两方面得出对中国的启示,为中国行政区划改革和区域经济发展提供借鉴。
