【摘要】：基于194个地级及以上城市2008-2013年的面板数据,研究高铁与城市交通对城市碳排放的影响效应。发现:1.高铁带来的广义可达性改善对城市碳排放的影响显著。通过促进区域均衡发展对东部城市有降低碳排放作用,而对中西部有增加碳排放作用;2.通过对私人交通的替代作用,城市公共交通对碳排放的影响为负。但公路对城市碳排放的影响为正;3.交通对碳排放的影响受城市规模的影响。其中,对东部地区的碳排放影响主要受经济规模影响,但对中部地区的影响主要受人口规模影响,说明中西部地区城市仍然处于不断集聚阶段;4.各交通变量对大规模城市的影响大于对中等城市的影响。研究结论:交通通过影响城市人口、经济、土地规模进而对城市碳排放产生影响。因此,通过交通引导城市人口、产业、土地合理布局,进而减少城市碳足迹具有重要意义。
[Abstract]:Based on panel data from 194 prefecture-level cities and above for 2008-2013. The effects of high-speed rail and urban traffic on urban carbon emissions are studied. 1. The broad accessibility improvement brought by high-speed rail has a significant impact on urban carbon emissions. By promoting regional balanced development, it can reduce carbon emissions in eastern cities. But it can increase carbon emission to the central and western regions; 2. The effect of urban public transport on carbon emissions is negative, but the impact of roads on urban carbon emissions is positive; 3. The impact of transportation on carbon emissions is affected by the scale of the city, in which the impact of carbon emissions on the eastern region is mainly affected by the economic scale, but the impact on the central region is mainly affected by the size of the population. It shows that cities in the central and western regions are still in the stage of continuous agglomeration. 4. The impact of traffic variables on large-scale cities is greater than on medium-sized cities. Conclusion: traffic affects urban carbon emissions by affecting urban population, economy, land scale and so on. It is of great significance to guide urban population, industry and land distribution through traffic, and to reduce urban carbon footprint.

【正文快照】： 一、问题的提出碳减排被视为生态文明建设的具体实践途径。然而,我国生态文明建设还处于初级阶段,中国仍然是全球最大的二氧化碳排放国,其二氧化碳排放量占全球排放总量的27%以上,交通行业占到总体能源消耗的12.7%[1]。碳减排,尤其是交通行业碳减排将是我国未来很长一段时间内
