This study aims to investigate the asymmetric fiscal decentralization effect on economic growth and environmental quality by using Pakistan data from 1984 to 2018. Our findings demonstrate that expenditure decentralization has asymmetric effects on economic growth and CO2 emissions in short- and long-run in Pakistan. Therefore, positive and negative fluctuations in expenditure decentralization affect economic growth and CO2 emissions differently in Pakistan. The results of asymmetric ARDL suggested that negative shock of revenue decentralization is reduced the economic growth and CO2 emissions in the short and long-run, while positive shock of revenue decentralization is reduced the economic growth and CO2 emissions. Our asymmetric results are country-specific and more effective in policy analysis in Pakistan. The outcomes of this study may also help Pakistan's local governments and the central government in addressing the problem of economic growth and environmental pollution.

研究巴基斯坦财政分权对经济增长和环境质量的不对称影响。

这项研究旨在通过使用1984年至2018年的巴基斯坦数据来研究财政分权对经济增长和环境质量的不对称影响。我们的研究结果表明，支出分权对巴基斯坦的短期和长期经济增长和CO2排放具有不对称影响。因此，支出分权的正负波动对巴基斯坦的经济增长和二氧化碳排放产生了不同的影响。不对称ARDL的结果表明，税收分权的负面冲击会在短期和长期内降低经济增长和CO2排放，而税收分权的正面冲击会降低经济增长和CO2排放。我们的不对称结果是针对特定国家的，在巴基斯坦的政策分析中更为有效。
