Abstract

ABSTRACT Lack of interregional trade data is often a major obstacle when doing economic analysis at the subnational level. This paper discusses a calibration procedure for estimating bilateral trade between the regions of a country. Our approach can be equivalently characterized as an application of the gravity-RAS or the doubly constrained gravity model method. Either way, a crucial element is represented by the distance elasticity parameter, which the user is expected to provide exogenously. We propose a way of estimating that parameter using standard econometric methods with readily available data and demonstrate our calibration procedure in a case study of Italy.

区域间贸易的校准重力模型

摘要缺乏区域间贸易数据往往是在国家以下一级进行经济分析的主要障碍。本文讨论了一个用于估计一个国家各地区之间双边贸易的校准程序。我们的方法可以等效地描述为重力RAS或双重约束重力模型方法的应用。无论哪种方式，关键元素都由距离弹性参数表示，期望用户外源性地提供距离弹性参数。我们提出了一种使用标准计量经济学方法和现成数据来估计该参数的方法，并在意大利的一个案例研究中演示了我们的校准程序。

期刊介绍： Spatial Economic Analysis is a pioneering economics journal dedicated to the development of theory and methods in spatial economics, published by two of the world"s leading learned societies in the analysis of spatial economics, the Regional Studies Association and the British and Irish Section of the Regional Science Association International. A spatial perspective has become increasingly relevant to our understanding of economic phenomena, both on the global scale and at the scale of cities and regions. The growth in international trade, the opening up of emerging markets, the restructuring of the world economy along regional lines, and overall strategic and political significance of globalization, have re-emphasised the importance of geographical analysis.
