摘要
文章运用基于公平与效率双重视角的旅游碳减排潜力指数测度2010—2020年长江经济带旅游碳减排潜力,采用基尼系数和标准差椭圆模型分析其区域差异与时空演变特征,并进一步采用PVAR模型探讨旅游碳减排潜力与旅游碳排放效率之间的交互效应。结果如下:①长江经济带旅游碳减排潜力整体呈波动式下降趋势,且形成“下游>中游>上游”的空间分布特征。②长江经济带旅游碳减排潜力基尼系数总体水平呈现波动缩小的态势,超变密度和区域间差异是总体差异的主要来源。③长江经济带旅游碳减排潜力标准差椭圆呈明显的“东北—西南”向分布格局,重心呈现向“西南—东北”方向移动的趋势。④长江经济带地区旅游碳减排潜力与旅游碳排放效率之间呈相互影响的负向动态关系,且二者互为格兰杰原因。
From the perspectives of fairness and efficiency,the study uses the tourism carbon emission reduction potential index to measure the tourism carbon emission reduction potential of the Yangtze River Economic Belt from 2010 to 2020,and uses the Gini coefficient and the standard deviation ellipse model to analyze its regional differences and spatialtemporal evolution characteristics,and further uses the PVAR model to explore the interactive response between tourism carbon emission reduction potential and tourism carbon emission efficiency.The results are as follows:1)The tourism carbon emission reduction potential shows a fluctuating downward trend in the Yangtze River Economic Belt,and forms the uneven spatial distribution characteristics which is higher in the lower reach of the Yangtze River than that in the upper and middle reaches.2)The overall level of Gini coefficient of tourism carbon emission reduction potential shows a trend of decreasing fluctuation in the Yangtze River Economic Belt,and the super variable density and regional differences are the main sources of overall differences.3)The standard deviation ellipse of tourism carbon emission reduction potential shows an obvious'northeast-southwest'distribution pattern in the Yangtze River Economic Belt,and the gravity center moves from the southwest to the northeast.4)There is a negative dynamic relationship between tourism carbon emission reduction potential and tourism carbon emission efficiency in the Yangtze River Economic Belt,and the two are Grangercauses.
