摘要

我们按地球轨道级别调查了美国太空活动对环境的影响。我们利用环境库兹涅茨框架，将两阶段最小二乘法应用于 1981 年至 2021 年收集的时间序列数据。结果表明，虽然轨道级别对发射并不重要，但轨道级别越高，对环境的影响似乎越明显。结果表明，有效载荷和火箭体会降低环境质量，从而增加对自然资源的需求，导致气候变化，并增加所有地球轨道级别的污染。

Space launches and the environment: As the earth orbit level matters, what can be done?

We investigate the impact of U.S. space activity on the environment by Earth orbit level. We exploit the environmental Kuznets framework and apply the two-stage least squares method to time series data collected between 1981 and 2021. The results demonstrate that, while the orbit level does not matter for the launch, the impact on the environment, however, seems to be more notable the higher the orbit level. The results suggest that payloads and rocket bodies degrade the quality of the environment and therefore increase demand for natural resources, contribute to climate change, and increase pollution at all Earth orbit levels.

期刊介绍： The Journal of Policy Modeling is published by Elsevier for the Society for Policy Modeling to provide a forum for analysis and debate concerning international policy issues. The journal addresses questions of critical import to the world community as a whole, and it focuses upon the economic, social, and political interdependencies between national and regional systems. This implies concern with international policies for the promotion of a better life for all human beings and, therefore, concentrates on improved methodological underpinnings for dealing with these problems.
