Remittances to the Philippines constitute a prominent part of its economy. However, remittances' effects on its environment have not been researched. In this regard, this research examines the direct and indirect impacts of remittance inflows on the Philippines' environmental sustainability for the 1977–2016 period by proposing a multivariate model, and by utilising the augmented ARDL and VECM methods to estimate this model. Our findings indicate that remittance inflows threaten environmental sustainability in the long-run both directly and indirectly through boosting income and energy (oil) consumption. The results additionally imply that income and energy consumption also increase the ecological footprint of the Philippines in the long-run. However, economic globalisation's long-run impact is insignificant, yet its short-run impact is significantly negative on the country's level of environmental degradation. Additionally, the findings reveal that the feedback hypothesis is valid between income and energy consumption in the long-run, but the neutrality hypothesis is valid in the short-run. This research's findings reveal that remittance inflows' impact on the environment is significant, and can occur through direct and various indirect channels, therefore, these inflows should be an integral part of sustainability policies in the Philippines, as ignoring them could cause further environmental decline.

汇往菲律宾的汇款如何影响其环境可持续性？基于增强型ARDL方法的证据

汇往菲律宾是菲律宾经济的重要组成部分。但是，尚未研究汇款对其环境的影响。在这方面，本研究通过提出多变量模型，并利用增强的ARDL和VECM方法估算该模型，研究了1977-2016年期间汇款流入对菲律宾环境可持续性的直接和间接影响。我们的研究结果表明，从长期来看，汇款流入通过增加收入和能源（石油）消耗而直接或间接地威胁着环境的可持续性。结果还暗示，从长远来看，收入和能源消耗也会增加菲律宾的生态足迹。但是，经济全球化的长期影响微不足道，然而，其短期影响对该国的环境恶化水平却是不利的。此外，研究结果还表明，从长远来看，反馈假设在收入和能源消耗之间是有效的，而在短期内，中立性假设是有效的。这项研究的发现表明，汇款流入对环境的影响是巨大的，并且可以通过直接和各种间接渠道发生，因此，这些流入应成为菲律宾可持续发展政策不可或缺的一部分，因为忽视它们可能会导致环境进一步恶化。但是中立假设在短期内是有效的。这项研究的发现表明，汇款流入对环境的影响是巨大的，并且可以通过直接和各种间接渠道发生，因此，这些流入应成为菲律宾可持续发展政策不可或缺的一部分，因为忽视它们可能会导致环境进一步恶化。但是中立假设在短期内是有效的。这项研究的发现表明，汇款流入对环境的影响是巨大的，并且可以通过直接和各种间接渠道发生，因此，这些流入应成为菲律宾可持续发展政策不可或缺的一部分，因为忽视它们可能会导致环境进一步恶化。
