This research analyzed the effect of tourism market diversification on Singapore's CO emissions by measuring the level of concentration of source countries in a foreign tourist basket of Singapore using a Herfindahl-Hirschman index. Our results indicated that the index fell over the period 1978-2020, which means the diversification of source countries of Singapore's foreign tourists increased. By applying the recent bootstrap and quantile ARDL models, we found that tourism market diversification and inward FDI act as stumbling blocks to CO emissions. In contrast, economic growth and primary energy consumption increase CO emissions. Policy implications are presented and discussed.
本研究通过使用赫芬达尔-赫希曼指数(HHI)来衡量外国游客在新加坡旅游篮子中来源国的集中程度,分析了旅游市场多元化对新加坡 CO2 排放的影响。结果表明,1978 年至 2020 年期间,该指数呈下降趋势,这意味着新加坡外国游客来源国的多元化程度有所增加。通过应用最近的 bootstrap 和分位数 ARDL 模型,我们发现旅游市场多元化和外国直接投资(FDI)流入成为 CO2 排放的障碍。相比之下,经济增长和初级能源消耗会增加 CO2 排放。本文提出并讨论了相关政策含义。
