This study explores the relationship between economic growth, tourism, and the environment in South Asian economies. It finds that factors such as GDP, human capital, globalization, and financial risk are interconnected and have long-term associations in these countries. The study employs various methodologies and tests to analyze the data. The author employs novel panel methodologies such as the method of moment of quantile regression analysis, slope heterogeneity, cross-section dependence test, and Westerlund cointegration. Additionally, a causality test along with the latest unit-root test is used. The results reveal important findings. As GDP expands, its impact on international tourism diminishes at higher quantiles, suggesting a decreasing effect. However, GDP still contributes positively to tourism across all quantiles. Human capital has a stronger effect on attracting tourists at lower quantiles, while globalization has varying impacts depending on the level of globalization in a country. Financial risk has a greater negative impact on tourism in larger economies compared to smaller ones. The study also examines the relationship between CO emissions and the variables under investigation. It finds that the effect of GDP on emissions decreases at higher quantiles, indicating a smaller contribution. Human capital has a larger effect on reducing emissions at lower quantiles, while the impact of globalization is more significant at higher quantiles. Moreover, an increase in financial risk leads to a decrease in emissions, particularly at lower quantiles. Based on these findings, the study suggests policy recommendations for South Asian economies. These include promoting sustainable tourism practices, investing in human capital development, encouraging responsible globalization, mitigating financial risks, and aligning tourism strategies with sustainable development goals.
本研究探讨了南亚经济体经济增长、旅游和环境之间的关系。研究发现,这些国家的 GDP、人力资本、全球化和金融风险等因素相互关联,存在长期关联。该研究采用了各种方法和检验来分析数据。作者采用了新颖的面板方法,如分位数回归分析的矩量法、斜率异质性、横截面相关性检验和 Westerlund 协整检验。此外,还使用了因果关系检验和最新的单位根检验。研究结果揭示了重要发现。随着 GDP 的增长,其对国际旅游的影响在较高分位数上减弱,表明影响逐渐减小。然而,GDP 对所有分位数的旅游仍然有积极的贡献。人力资本在较低分位数上对吸引游客有更强的影响,而全球化的影响则取决于一个国家的全球化程度。金融风险对较大经济体的旅游负面影响大于较小经济体。该研究还考察了 CO2 排放与研究变量之间的关系。研究发现,GDP 对排放的影响在较高分位数上减小,表明贡献较小。人力资本对降低较低分位数的排放有更大的影响,而全球化的影响在较高分位数上更为显著。此外,金融风险的增加会导致排放减少,尤其是在较低分位数上。基于这些发现,本研究为南亚经济体提出了政策建议。这些建议包括促进可持续旅游实践、投资人力资本开发、鼓励负责任的全球化、缓解金融风险以及使旅游战略与可持续发展目标保持一致。
