摘要:

【目的】探究长三角地区碳排放效率时空特征及影响因素,更好地为长三角地区根据自身实际发展情况制定有针对性的碳减排措施,促进区域的协调发展。【方法】基于非期望产出的SBM(slacks-based measure)模型测度长三角地区41个城市的碳排放效率,结合探索性空间分析方法对长三角地区碳排放效率的时空特征进行探究,从规模、结构、技术3个维度出发,将空间因素考虑在内构建空间计量模型并深入分析长三角地区碳排放效率的影响因素。【结果】长三角地区41个城市碳排放效率存在较大差异,不均衡现象明显;碳排放效率高值区主要分布在上海市和江苏省,碳排放效率低值区集中分布在安徽省,空间差异特征明显;碳排放效率在空间上表现出较强的正相关性,空间聚集态势明显且空间集聚主要以H-H和L-L类型集聚为主;经济发展规模、产业结构对于碳排放效率的提升有显著的抑制作用,外商直接投资对于碳排放效率有明显的正向驱动作用。【结论】空间杜宾模型(SDM)的效应分解结果表明,注重经济发展质量、调整产业结构是提升长三角地区城市碳排放效率的重要途径。

Abstract:

【Objective】The study explored the spatio-temporal characteristics and influencing factors of carbon emission efficiency in the Yangtze River Delta, to better formulate carbon emission reduction measures for the region according to its actual development conditions, and to promote the coordinated development of the region.【Method】Based on the slacks-based measure(SBM) model of undesired output, the carbon emission efficiency of 41 cities in the Yangtze River Delta were measured and the spatiotemporal characteristics of carbon emission efficiency in the Yangtze River Delta were analyzed through exploratory spatial data analysis. Constructing a spatial econometric model with spatial factors from the three dimensions of scale, structure and technology allowed analysis of the influencing factors of carbon emission efficiency in the Yangtze River Delta. 【Result】Large differences in carbon emission efficiency were evident among 41 cities in the Yangtze River Delta. Imbalance was obvious. The high-value areas of carbon emission efficiency were mainly distributed in the Shanghai and Jiangsu provinces, and the areas with low carbon emission efficiency were concentrated in the Anhui Province, with obvious spatial differences. Carbon emission efficiency showed a strong positive correlation in space, spatial agglomeration was obvious, and spatial agglomeration was mainly H-H and L-L. The scale of economic development and industrial structure had a significant inhibitory effect on the improvement of carbon emissions efficiency, and foreign direct investment had an obvious positive driving effect on carbon emissions efficiency. 【Conclusion】 The effect decomposition results of Spatial Doberman model shows that focusing on the quality of economic development and adjusting the industrial structure is an important way to improve the carbon emission efficiency of cities in the Yangtze River Delta.

Key words: carbon emission efficiency, non-expected outputs, spatio-temporal characteristics, spatial Doberman model(SDM), Yangtze River Delta region
