Evolution of trade patterns in the new EU member states

The paper analyses the evolution of the trade specialization pattern in the new EU member states. Relying on the empirical approach of the Markov transition matrices it analyses both the changes in the external shape of the distribution of comparative advantages and the intra‐distribution dynamics. The new members show a dynamic trade pattern: they gained comparative advantages relatively fast in sectors in which they were lagging behind at the beginning of the transition, notably in some ‘high tech’ products. In addition, many specialization improvements occurred in those items for which world demand expanded at the fastest rate over the nineties.     

Technological forecasting at the Korean stock market: A dynamic competition analysis using Lotka–Volterra model

The purpose of this paper is to attempt to analyze the dynamic relationship between the Korean Stock Exchange (KSE) and Korean Securities Dealers Automated Quotation (KOSDAQ), two competing markets at the Korean stock market, in the viewpoint of technological forecasting of competition. The Lotka–Volterra system of equations, one well-known competitive diffusion models, is adopted to represent the competitive situations of the Korean stock market and it is estimated using daily empirical index data of KSE and KOSDAQ during 1997–2001. The results show that there existed a predator–prey relationships between two markets in which KSE acted as a prey for the time being after the emergence of KOSDAQ. This interaction was altered to symbiotic relationship and finally to pure competition relationship. We also perform an equilibrium analysis of the estimated Lotka–Volterra equations. As a result, we find that there is an equilibrium point in a dynamic sense. However, the equilibrium point could be unstable in the latest pure competition relationship.     

A multiregional model of China and its application

China's rapid economic transformation since 1979 has been accompanied by a stark regional disparity with the coastal provinces integrating swiftly into the world markets while inland regions lagging far behind in the industrialisation process. The growth imbalance has placed China's provinces into different stages of development and called for different policy responses to deal with different challenges they are facing. Similarly, a national policy initiated by the central government is likely to be interpreted and implemented in different ways when local governments take into consideration the different conditions in their localities. Therefore, it would be extremely valuable for policy makers and researchers to have an analytical tool that is capable of studying interactions among the provincial economies and the dynamic relationship between the centre and local governments. The multiregional econometric model of China presented in this paper is the first attempt to provide such a tool. The pioneering model consists of over 1200 equations, covering 30 provinces of China that are linked by inter-regional flows of goods and services. The model is used to study the impact of fiscal recentralisation in the 1990s. The counterfactual simulation results show that when China's central government diverted tax revenue from provincial governments, it achieved higher budgetary revenue for the central government but at the expense of lower overall budgetary revenue and slower economic growth.     

A Study of Mathematic Model to the Development of Regional Industry Cluster

This paper analyzes the factors that influence the development of regional industry cluster, which are location factors, accumulatable factors, and external factors. Then regarding the similarity between the development of industry cluster and biology community, a modified logistic model is built, and a field study is made between the real instances and the model.     

Conceptual Model for Urban Competitiveness

Urban competitiveness is always the focus of researches on urban economy. The variety of definitions and evaluation systems of urban competitiveness are the results of lack of accurate and comprehensive understanding on urban competitiveness. This paper reviews five groups of definitions on urban competitiveness and establishes a conceptual model for urban competitiveness.

国内外原油市场收益率及其波动性的双长记忆性测度

本文基于我国原油现货价格和欧洲Brent原油现货价格的数据,运用多种计量模型对原油市场收益率及其波动性的长记忆性进行测度。研究发现,我国原油市场收益率序列不存在长相依性特征,波动率序列则存在长记忆性效应;国外原油市场收益率及波动率序列均存在显著且较强的长记忆性。同时,检验结果表明,采用Student-t分布来刻画"尖峰厚尾"分布性质并利用TGARCH模型来描述"杠杆效应"是非常必要的。     

G公司内部控制变革研究——从会计控制到高级导航系统

控制论和权变理论认为,公司内部控制应根据其所处的内外部条件随机应变。G公司为应对内外环境的变迁实施了"新一代内部控制",并将其定位为"高级导航系统",以强化内部控制的决策支持作用。研究发现,G公司内部控制变革的驱动力主要来自环境的变化,多次并购引起的规模扩张及自身组织结构变化;新的控制系统在控制目标、控制方法、重点控制领域、新的信息系统构建、组织结构及内部控制实施人员的角色再定位等方面进行了变革。本文在内部控制变革框架基础上,通过对内部控制部门员工实施问卷调查,检验了该公司从传统的会计控制到新一代内部控制转变的效果。     

固定生产要素对经济增长的作用研究——基于扩展的拉姆齐模型

在标准的拉姆齐模型中引入一种固定生产要素(例如土地)来进行模型扩展。固定生产要素是指那些总量固定的要素,但随人口的增加这类要素的人均数量会减少。模型分析得出的主要结论是固定要素对经济的长期增长起着重要作用,人均固定要素的减少对经济的负面影响在一定程度上可通过人均资本的增加来弥补,这种程度取决于固定要素与资本的替代弹性。     

论行政事业单位内部会计控制与管理

随着我国机构改革的不断深入,行政事业单位社会分工更加细化,责、权、利更加明确。在新形势下,对行政事业单位会计人员提出了更高的要求。同时,也对行政事业单位内部控制制度提出了更高的标准。因此,建立健全行政事业单位内部会计控制制度对防止国有资产流失,保证国家财政资金运行安全十分必要。但是,我国行政事业单位内部会计控制还存在不少问题。
