Abstract

Several strands of the static and dynamic theoretical constructs and the empirical applications in the subject of economics owe substantially to the well-known principles of physical sciences. The present article explores as to how the development of the popular gravity models in international trade can be traced back to Newton’s law of gravitation, and to both Ohm’s Law and Kirchhoff’s Law of current electricity, as well as to the pattern recognition techniques commonly deployed in scientific applications. In addition to surveying these theoretical analogies, the article also offers numerical applications for observed trade patterns between India and a set of countries.

国际贸易中的引力模型：经济物理学探索

经济学学科中的静态和动态理论结构以及实证应用的几个方面在很大程度上归功于众所周知的物理科学原理。本文探讨了国际贸易中流行的引力模型的发展如何可以追溯到牛顿引力定律、欧姆定律和基尔霍夫电流定律，以及科学应用中常用的模式识别技术。除了考察这些理论类比外，本文还为观察到的印度与一系列国家之间的贸易模式提供了数字应用。JEL分类：F41、F42、C61、F47

期刊介绍： The purpose of the Journal is to publish (in English language) peer-reviewed articles, reviews and scholarly comments on issues relating to contemporary global macroeconomics and public finance by which is understood: The Journal is for all professionals concerned with contemporary Macroeconomics and Public Finance and is a forum for all views on related subjects. The Editorial Board welcomes articles of current interest on research and application on the areas mentioned above. The Journal will be international in the sense that it seeks research papers from authors with an international reputation and articles that are of interest to an international audience. In pursuit of the above, the journal shall: a. draw on and include high quality work from the international community of scholars including those in the major countries of Asia, Europe, Asia Pacific, the United States, other parts of the Americas and elsewhere with due representation for considerations of the readership. The Journal shall include work representing the major areas of interest in contemporary research on Macroeconomics and Public Finance and on a wide range of issues covering macro- economics, tax and fiscal issues, banking and finance, international trade, labour economics, computational and mathematical methods, etc. The Journal would particularly engage papers on pure and applied economic theory and econometric methods. b. avoid bias in favour of the interests of particular schools or directions of research or particular political or narrow disciplinary objectives to the exclusion of others. c. ensure that articles are written in a terminology and style which makes them intelligible, not merely within the context of a particular discipline or abstract mode, but across the domain of relevant disciplines.
