摘要

与联合国可持续发展目标一致，提高环境质量的全球努力只有通过使包括交通运输在内的碳密集型行业脱碳才能实现。尽管新兴经济体对世界经济做出了巨大贡献，但随着工业化、城市流动性和交通的增加，它们难以实现环境的可持续性。因此，本研究以2004年至2022年11个新兴经济体为研究对象，采用动态固定效应和CS-ARDL估计技术，分析了环境税（ET）、绿色技术创新（GTI）和生物燃料使用（BF）是否减少了交通运输部门的排放。实证分析还通过整合智商与GTI、BF和ET的直接和调节效应，揭示了制度质量（IQ）的重要作用。实证证据表明，虽然BF（- 0.138）、GTI（- 0.074）和IQ（- 1.303）改善了交通运输部门的脱碳过程，但从长期来看，ET（- 0.123）并没有显著地使交通运输部门脱碳。此外，研究结果揭示了IQ在新兴经济体GTI（- 0.174）、BF（- 0.129）和ET（- 0.193）的减排效果调节中的重要作用，表明善意的制度支持对交通运输部门的长期可持续转型至关重要。因此，本研究建议包括生产第二代生物燃料的政策要求，通过绿色创新实现交通基础设施的现代化，并通过分散的治理体系加强制度设置，以实现更高的效益和环境目标。

Fuelling the low-carbon transportation sector in emerging economies: Role of institutional quality, environmental tax, green technology innovation and biofuel

Aligning with the United Nations SDGs, global efforts to enrich environmental quality can only be realized by decarbonizing carbon-intensive sectors, including transportation. Although emerging economies contribute substantially to the world economy, they struggle to achieve environmental sustainability with increasing industrialization, urban mobility, and transportation. Therefore, this study analyses whether the environmental tax (ET), green technology innovation (GTI), and biofuel use (BF) abate emissions from the transportation sector, considering 11 emerging economies from 2004 to 2022 using the dynamic fixed effect and CS-ARDL estimation techniques. The empirical analysis also discloses the imperative role of institutional quality (IQ) by integrating IQ's direct and moderation effects with GTI, BF, and ET. The empirical evidence highlights that while BF (−0.138), GTI (−0.074), and IQ (−1.303) ameliorate the decarbonization process, ET (−0.123) does not significantly decarbonize the transportation sector in the long-run. Furthermore, the results disclose an important role of IQ in moderating the emissions mitigation effectiveness of GTI (−0.174), BF (−0.129), and ET (−0.193) in emerging economies, indicating that benevolent institutional support is crucial for the sustainable transformation of the transportation sector in the long-run. Thus, this study suggests including policy mandates for generating second-generation biofuels, modernization of transportation infrastructure through green innovations, and strengthening institutional settings through a decentralized governance system to realize higher benefits and environmental goals.

期刊介绍： Transport Policy is an international journal aimed at bridging the gap between theory and practice in transport. Its subject areas reflect the concerns of policymakers in government, industry, voluntary organisations and the public at large, providing independent, original and rigorous analysis to understand how policy decisions have been taken, monitor their effects, and suggest how they may be improved. The journal treats the transport sector comprehensively, and in the context of other sectors including energy, housing, industry and planning. All modes are covered: land, sea and air; road and rail; public and private; motorised and non-motorised; passenger and freight.
