本文利用一个由77个国家组成的小组，在1980-2000年期间考察了政府支出对环境的影响。我们估计了政府在污染方面的支出的直接和间接影响。间接影响主要通过政府支出对收入的影响以及收入水平对污染的后续影响来发挥作用。考虑到动态性质和潜在的内生性的关系检查，适当的计量经济学方法被使用。对于二氧化硫，政府支出估计对人均排放量有负的直接影响，而对二氧化碳污染的直接影响微不足道。对SO2的间接影响在低收入水平为负，随着收入的增加而变为正，而对CO2的间接影响在大部分样本范围内仍然为负。由此产生的总效应遵循间接效应的模式，间接效应支配着每种污染物各自的直接效应。调查结果对政策的影响因所考虑国家的收入水平而异。(C) 2013 Elsevier B.V.版权所有
This paper examines the impact of government spending on the environment using a panel of 77 countries for the time period 1980-2000. We estimate both the direct and indirect effects of government spending on pollution. The indirect effect in particular operates through the impact of government spending on income and the subsequent effect of the income level on pollution. To take into account the dynamic nature and the potential endogeneity in the relationships examined, appropriate econometric methods are used. For SO2, government spending is estimated to have a negative direct impact on per capita emissions, while the direct effect is insignificant on CO2 pollution. The indirect effect on SO2 is negative for low income levels and becomes poSitive as income increases, while it remains negative for CO2 for the most part of the sample range. The resultant total effects follow the patterns of the indirect effects, which dominate their respective direct ones for each pollutant. Policy implications from the results vary depending on the income level of the considered countries. (C) 2013 Elsevier B.V. All rights reserved.
