中国可持续发展水平的区域差异及动态演进

Regional Differences and Dynamic Evolution of Sustainable Development Level in China

文章在可持续发展目标框架下构建了本土化的可持续发展评价指标体系,将其聚类于经济、社会和生态三个维度,进一步利用熵值法、Dagum基尼系数分解法等方法,考察其区域差异及动态演进趋势。研究发现:(1)中国的可持续发展水平持续上升,经济、社会和生态可持续发展呈现良好趋势,但生态建设仍然是可持续发展的突出短板;(2)中国可持续发展水平总体差异呈下降趋势,并具有鲜明的区域非均衡特征;(3)各地区的空间异质性特征突出,东部-西部、东部-中部子群间差异较大,但呈现显著缩小趋势,并且子群间差异是总体差异的主要来源;(4)中国以及各地区可持续发展水平均存在σ收敛,但东部与中西部地区收敛速度差异显著;(5)各地区空间相关性不断增强,绝大多数省份位于“H-H”和“L-L”集聚板块,形成了以东部地区为主的可持续发展高水平区域。

Based on the framework of sustainable development,this paper constructs a localized sustainable development evaluation index system,clustering it into economic,social and ecological dimensions,and further uses entropy method and Dagum Gini coefficient decomposition to investigate its regional differences and dynamic evolution trend.The results go as the following:(1)The level of sustainable development in China continues to rise,and its economic,social and ecological sustainable development shows a good trend,but ecological construction is still a prominent weak link in sustainable development.(2)The overall difference in the level of sustainable development in China shows a declining trend,and has a distinct regional imbalance.(3)The spatial heterogeneity of different regions is prominent,and the differences between east-west and east-central subgroups are large,but presenting a significant narrowing trend,and the differences between subgroups are the main source of the overall differences.(4)There isσconvergence in the sustainable development level of China and all regions,but the convergence speed is significantly different between the eastern and central and western regions.(5)The spatial correlation of all regions is increasing,and the vast majority of provinces are located in the“H-H”and“L-L”agglomeration plates,forming a high-level region of sustainable development mainly in the eastern region.
