Abstract

Abstract Although the impacts of income, population growth, and other important determinants of land-use change have been widely studied, there is less understanding of how spatial spillovers matter. Utilizing a spatial econometric approach, we investigate the main determinants of natural landscape conversion, focusing on quantifying local and global spatial spillovers. The empirical investigation applies to the Edmonton Metropolitan Region and the Calgary Regional Partnership in Canada. Key results include: (1) determinants of land conversion have significant spillover effects; (2) income, population density, road density, natural land endowment and land suitability for agriculture are all found to have influences on natural land conversion both in the own and neighboring areas; and (3) local (i.e., within the immediate neighboring areas) and global (in the entire study region) spillovers are different in strength and direction. Our work provides useful information for understanding the spillover issues in land conservation, resource governance, and optimal conservation design.

调查空间溢出效应在加拿大城市化中作为土地转换决定因素的作用

虽然收入、人口增长和其他重要的土地利用变化决定因素的影响已经得到了广泛的研究，但对空间溢出效应的影响却知之甚少。利用空间计量经济学方法，我们研究了自然景观转换的主要决定因素，重点是量化局部和全球空间溢出效应。实证研究适用于加拿大埃德蒙顿大都市区和卡尔加里区域伙伴关系。主要研究结果包括:(1)土地非农化决定因素具有显著的溢出效应;(2)收入、人口密度、道路密度、自然土地禀赋和农业用地适宜性均对本区和周边地区的自然土地非农化有影响;(3)局部(即邻近区域内)和全局(整个研究区域内)的溢出效应在强度和方向上存在差异。我们的研究为理解土地保护、资源治理和最优保护设计中的溢出问题提供了有用的信息。

期刊介绍： Environment and Development Economics is positioned at the intersection of environmental, resource and development economics. The Editor and Associate Editors, supported by a distinguished panel of advisors from around the world, aim to encourage submissions from researchers in the field in both developed and developing countries. The Journal is divided into two main sections, Theory and Applications, which includes regular academic papers and Policy Options, which includes papers that may be of interest to the wider policy community. Environment and Development Economics also publishes occasional Policy Fora (discussions based on a focal paper). From time to time the journal publishes special issues based on a particular theme.
