交通基础设施、市场一体化与能源效率

Transportation Infrastructure,Market Integration and Energy Efficiency

持续提升能源效率是推动高质量发展、实现碳中和目标的重要路径。本文从理论和实证两方面分析了交通基础设施对能源效率的影响及其机制。结果表明,交通基础设施可以显著提升各城市能源效率,并且这一影响在西部、非中心城市和非资源禀赋型城市更为明显。机制分析表明,交通基础设施可以促进市场一体化,提升要素的跨区流动,从而改善能源效率。基于此,建议地方政府加大交通基础设施投资,尤其是在西部、非中心城市和非资源禀赋型城市;同时,加快建设全国统一大市场,畅通交通基础设施发挥作用的渠道机制。

Continuously improving energy efficiency is key to promoting high-quality development and achieve carbon neutrality goals.This paper analyzes the impact and mechanism of transportation infrastructure on energy efficiency from both theoretical and empirical perspectives.The results indicate that transportation infrastructure can significantly improve energy efficiency in various cities,and this impact is more pronounced in western regions,non-central cities,and nonresource-endowment cities.Mechanism analysis shows that transportation infrastructure can promote market integration,enhance cross regional flow of factors,and thus improve energy efficiency.Based on the results,it is recommended that local governments increase investment in transportation infrastructure,especially in western regions,non-central cities,and nonresource-endowment cities.At the same time,accelerate the construction of a unified national market,facilitating the channel mechanism for the development of transportation infrastructure.
