Abstract

This research aims to determine whether institutional quality thresholds exist in the relationship between economic growth and carbon emissions for 99 countries from 2008 to 2015. Using a panel threshold autoregressive estimation, the findings reveal a significant threshold effect of institutional quality in the carbon emissions -economic growth nexus. Carbon emissions rise in response to economic growth when institutional quality is below the threshold; on the other hand, emissions decrease in response to institutional quality above the threshold. The results confirmed the existence of the environmental kuznets curve. Further, the results also validated through robustness testing by splitting the sample into developed and developing countries, indicating that economic growth with better institutional quality can help reduce emissions. Therefore, as a fundamental tactic to address environmental issues alongside economic growth and establish the path for sustainable development, policymakers should concentrate on strengthening institutional quality.

在制度质量存在门槛效应的情况下重新审视环境库兹涅茨曲线

本研究旨在确定 2008 年至 2015 年 99 个国家的经济增长与碳排放关系中是否存在制度质量门槛。通过面板阈值自回归估计，研究结果表明，在碳排放与经济增长的关系中，制度质量存在显著的阈值效应。当制度质量低于阈值时，碳排放会随着经济增长而增加；另一方面，当制度质量高于阈值时，碳排放会随着经济增长而减少。结果证实了环境库兹涅茨曲线的存在。此外，通过将样本分为发达国家和发展中国家进行稳健性检验，结果也得到了验证，表明经济增长的同时提高制度质量有助于减少排放。因此，作为在实现经济增长的同时解决环境问题并确立可持续发展道路的基本策略，政策制定者应着力加强制度质量。

期刊介绍： Environment, Development and Sustainability is an international and multidisciplinary journal covering all aspects of the environmental impacts of socio-economic development. It is also concerned with the complex interactions which occur between development and environment, and its purpose is to seek ways and means for achieving sustainability in all human activities aimed at such development. The subject matter of the journal includes the following and related issues: -mutual interactions among society, development and environment, and their implications for sustainable development -technical, economic, ethical and philosophical aspects of sustainable development -global sustainability - the obstacles and ways in which they could be overcome -local and regional sustainability initiatives, their practical implementation, and relevance for use in a wider context -development and application of indicators of sustainability -development, verification, implementation and monitoring of policies for sustainable development -sustainable use of land, water, energy and biological resources in development -impacts of agriculture and forestry activities on soil and aquatic ecosystems and biodiversity -effects of energy use and global climate change on development and sustainability -impacts of population growth and human activities on food and other essential resources for development -role of national and international agencies, and of international aid and trade arrangements in sustainable development -social and cultural contexts of sustainable development -role of education and public awareness in sustainable development -role of political and economic instruments in sustainable development -shortcomings of sustainable development and its alternatives.
