The study empirically explores the long-run dynamic influence of output, tourism, energy use, trade, financial development, and urbanization on CO emissions in the framework of EKC for Asian economies for the time period 1995-2017. In this study, we tackle cross-sectional dependence problem and use CADF and CIPS unit root tests in contrast to conventional unit root tests. Moreover, we employ LM bootstrap panel co-integration test. The results of DOLS show that GDP and GDP squares have opposite signs which shows inverted u-shaped hypothesis between GDP growth and carbon emissions. We find an evidence of EKC proposition in case of Asian economies. Tourism has a vital role in increasing environment degradation of Asian economies as magnitude of coefficient is 0.132. Moreover, energy use, urbanization, trade, and financial development have direct and a profound impact on environmental degradation. The empirical results thus point to the fact that tourism, trade openness, and urbanization have contributed to the environmental degradation in the Asian region. Hence, the counties of the region should harness renewable energy sources along with environment-friendly technologies to support the tourism at a sustainable level that may be conducive to economic growth and environmental quality as well.
该研究在1995 - 2017年期间亚洲经济体的环境库兹涅茨曲线框架下,实证探究了产出、旅游业、能源使用、贸易、金融发展和城市化对碳排放的长期动态影响。在本研究中,我们解决了横截面依赖性问题,并与传统单位根检验不同,使用了CADF和CIPS单位根检验。此外,我们采用了LM自举面板协整检验。动态最小二乘法(DOLS)的结果表明,国内生产总值(GDP)及其平方项具有相反的符号,这表明GDP增长与碳排放之间存在倒U形假设。我们发现亚洲经济体存在环境库兹涅茨曲线命题的证据。旅游业对亚洲经济体环境退化的加剧起着至关重要的作用,因为系数大小为0.132。此外,能源使用、城市化、贸易和金融发展对环境退化有直接且深远的影响。实证结果因此表明,旅游业、贸易开放度和城市化导致了亚洲地区的环境退化。因此,该地区各国应利用可再生能源以及环境友好型技术,以可持续的水平支持旅游业,这也可能有利于经济增长和环境质量。
