摘要

这项研究有两个目的。第一个目的是,利用国际国家风险指南(ICRG)评级机构确定的经济和金融风险因素,用詹克斯自然断裂(JNB)分类技术对各国从这些因素中得到的分数进行重新分类,并根据这种分类创建各国的专题地图来比较各国。我们研究的第二个目的是基于ICRG确定的经济和金融风险因素,使用地理加权回归(GWR)方法(地理信息系统(GIS)分析技术之一)创建各国的经济和金融风险地图。在对纳入研究的变量进行GWR分析之前,采用Moran指数分析作为空间自相关的主要度量。Moran分析的结果是,国家之间存在统计学上显著的正自相关。换句话说,研究发现,在经济和金融风险方面,这些国家在空间上相互依赖。根据GWR分析的结果,绘制了被检查国家的风险图,并揭示了更有活力、更有意义或更敏感、更具体、更容易理解的结果。根据这些结果,可以看出GWR技术也可以应用于经济和金融领域。此外,该研究汇集了经济、金融和地理领域,带来了不同的跨学科视角。

Geographic Information System Based Economic And Financial Risk Analysis: The Case Of Europe And Central Asia
The study has two purposes. The first purpose is, using the economic and financial risk factors determined by the International Country Risk Guide (ICRG) rating agency, to reclassify the scores that countries get from these factors with the Jenks Natural Breaks (JNB) classification technique and to compare countries by creating their thematic maps according to this classification. The second purpose of our study  is to create economic and financial risk maps of countries by using the Geographical Weighted Regression (GWR) method, which is one of the Geographical Information System (GIS) analysis techniques, based on the economic and financial risk factors determined by the ICRG. Before the GWR analysis for the variables included in the research, Moran Index analysis was performed as the main measurement of spatial autocorrelation. As a result of the Moran analysis, it was determined that there was a statistically significant positive autocorrelation between the countries. In other words, it has been seen that the countries examined have spatial dependence on each other in terms of economic and financial risk. According to the results of the GWR analysis, risk maps of the examined countries were created and more dynamic, more meaningful or more sensitive, more specific and visually easier to understand results were revealed. And according to these results, it has been seen that the GWR technique can also be used in the fields of economy and finance. In addition, the study brought a different interdisciplinary perspective  by bringing together the fields of economy, finance and geography.
