Abstract

This study examines the impact of economic institutions on ecological footprint and their spatial spillover effects globally, covering the period from 2000 to 2021. We focus on economic institutions because institutions that espouse economic freedom are essential for safeguarding environmental quality. We hypothesize that the spatial influence of these institutions varies both globally and regionally. The Moran's I test reveals significant spatial associations among countries, while the Wald and likelihood tests identify the spatial Durbin model as the most appropriate approach. Furthermore, the Hausman test indicates that a fixed effects model best captures the coefficients. Globally, economic institutions demonstrate a direct reduction effect of 16.4% and a spillover reduction effect of 4.4% on ecological footprint. However, these effects show considerable regional variation. In North America, East Asia and the Pacific, the Middle East, North Africa, Europe, and Central Asia, economic institutions effectively reduce ecological footprint, while their impact is negligible in other regions. These regional differences underscore the importance of addressing institutional deficiencies, encouraging policymakers in regions with limited effects to learn from best practices to enhance institutional effectiveness. These insights collectively advance the literature on economic institutions and environmental economics, emphasizing regional policy adaptation and the transboundary effects of institutional quality. The findings further reveal that economic institutions moderate GDP per capita to curb ecological footprint significantly. These conclusions hold even after addressing endogeneity using the generalized spatial two-stage least squares method. The study recommends that policies promoting economic freedom are essential to mitigate global environmental degradation.

经济制度对环境的溢出效应:来自空间计量分析的全球证据。
本研究考察了2000 - 2021年全球经济制度对生态足迹的影响及其空间溢出效应。我们关注经济制度,因为支持经济自由的制度对保护环境质量至关重要。我们假设这些机构的空间影响在全球和区域都是不同的。Moran's I测试揭示了国家之间显著的空间关联,而Wald和似然测试则认为空间Durbin模型是最合适的方法。此外,Hausman检验表明,固定效应模型最能反映这些系数。在全球范围内,经济制度对生态足迹的直接减少效应为16.4%,溢出减少效应为4.4%。然而,这些影响显示出相当大的区域差异。在北美、东亚和太平洋、中东、北非、欧洲和中亚,经济制度有效地减少了生态足迹,而在其他地区,经济制度的影响可以忽略不计。这些地区差异强调了解决制度缺陷的重要性,鼓励效果有限的地区的决策者学习最佳做法,以提高制度有效性。这些见解共同推进了经济制度和环境经济学的文献,强调了区域政策适应和制度质量的跨界效应。研究结果进一步表明,经济制度调节人均GDP对生态足迹具有显著的抑制作用。这些结论甚至在使用广义空间两阶段最小二乘法处理内生性后仍然成立。该研究建议,促进经济自由的政策对于缓解全球环境恶化至关重要。
