摘要
中国经济已经进入高质量发展阶段,新型城镇化建设是经济高质量发展与碳达峰、碳中和目标实现的重要抓手和载体。既有文献围绕城镇化转型的经济环境效应形成了一批卓有成效的研究成果,但鲜有文献从外生冲击视角分析新型城镇化建设对能源利用效率的影响机理与政策效果。因此,文中结合中国现实情境,基于“技术进步—人口集聚—城市扩张”的理论分析框架,在深入阐释新型城镇化综合试点政策究竟如何影响能源利用效率的基础上,创新性地突破现有实证分析思路,将能源利用效率划分为全要素能源效率和绿色全要素能源效率,利用新型城镇化综合试点政策作为一项准自然实验,采用双重差分方法基于中国285个城市的平衡面板数据来考察新型城镇化建设对能源利用效率的影响效应及作用机制。研究结果表明:①在一系列稳健性检验后,新型城镇化综合试点政策显著降低了全要素能源效率和绿色全要素能源效率,并且年度效应呈现出逐年递增的趋势。②影响机制检验表明,新型城镇化综合试点政策主要通过促进技术进步、吸引人口集聚和刺激城市扩张来阻碍能源利用效率提高。③地区偏向性政策检验表明,向中西部倾斜的地区偏向性政策并没有在新型城镇化的节能方面发挥效果。④城市群模式检验表明,加入城市群有助于增强新型城镇化综合试点政策对能源利用效率的作用。该研究为下一阶段中国全面推进新型城镇化建设,规避不利因素,实现新型城镇化高质量发展与能源利用效率提高的“双赢”局面提供了经验证据和政策启示。
China has entered the stage of high-quality development,and the construction of new-type urbanization is an important approach for the realization of the country’s high-quality economic development as well as reaching peak carbon emissions and achieving carbon neutrality.The existing literature has produced a number of fruitful research results on the economic and environmental effects of the transformation of urbanization.However,few studies have tested the effects of the new-type urbanization construction on energy efficiency and their mechanisms from the perspective of exogenous impact.Therefore,in the context of China’s actual situation,this paper constructed a theoretical framework of‘technological progress-population agglomeration-urban expansion,’and then deeply explained how the comprehensive pilot policy for new-type urbanization affected energy efficiency.Based on the panel data of 285 cities in China,this paper made an innovative breakthrough from the existing empirical analyses by dividing energy efficiency into total-factor energy efficiency and green total-factor energy efficiency,choosing the comprehensive pilot policy for new-type urbanization as a quasinatural experiment,and using the difference-in-differences method to examine the mechanisms and impact of new-type urbanization on energy efficiency.The results showed that:①After a series of robustness tests,the impact of the comprehensive pilot policy for newtype urbanization on total-factor energy efficiency and green total-factor energy efficiency was significantly negative,and the effect increased year by year.②Mechanism analysis showed that new-type urbanization mainly hindered the improvement of energy efficiency by promoting technological progress,boosting population agglomeration,and stimulating urban expansion.③According to the analysis of the effect of the regional biased policy,the regionally biased policy leaning toward the central and western regions did not promote the energy-saving effect of new-type urbanization.④Ac
