交通建设高质量发展与低碳化关系研究

Research on Relationship between High Quality Development and Low Carbon in Transportation Construction

摘要:

在“双碳”目标背景下，交通建设低碳化发展的需求越来高，亟待找到高质量发展推动低碳化发展的量化评价方法。依托2011—2020年江苏省交通建设相关指标数据，基于三阶段DEA模型，确定投入产出指标，分三阶段分别从纯技术和规模综合效率角度探寻不同碳排放水平对交通建设高质量发展的作用强度。结果表明，江苏省交通建设高质量发展能够促进碳排放量的减少，虽然2012—2016年表现不佳，但其余年份表现良好，推动碳排放效率提升的效果整体呈现出先下降后上升的趋势。研究结果可为交通建设高质量、低碳化融合发展提供依据。

Abstract:

In the context of "dual carbon", the demand for low-carbon development in transportation construction is increasing, and it is urgent to find a quantitative evaluation method for high-quality development to promote low-carbon development. Relying on the relevant indicator data of transportation construction in Jiangsu Province from 2011 to 2020, and based on a three-stage DEA model, the input-output indicators are determined. From three stages and from the perspective of pure technology and scale comprehensive efficiency, the impact of different carbon emission levels on the high-quality development of transportation construction is explored. The results indicate that the high-quality development of transportation construction in Jiangsu Province can promote the reduction of carbon emissions. With poor performance from 2012 to 2016 and good performance in other years, the overall effect of promoting the improvement of carbon emission efficiency shows a trend of first decreasing and then increasing. The study result can provide a basis for the high-quality and low-carbon integrated development of transportation construction.
