共同富裕是中国特色社会主义的本质要求，而经济高质量发展是实现共同富裕的坚实物质基础，从共同富裕视角出发客观反映经济高质量发展建设成效具有重要意义。将可行能力理论与新发展理念相结合，构建包含功能和能力两个维度的经济高质量发展评价指标体系，选取2006—2021年长三角地区数据，利用熵值法测度其经济高质量发展水平，结合核密度估计、Markov链等方法刻画经济高质量发展的动态演进过程，并以五年规划发布时间作为分析经济高质量发展阶段变动的特征时点，从时间、空间、区域等维度深入分析长三角地区的经济高质量发展水平。研究发现，长三角地区经济高质量发展水平在2006—2021年呈现波动上升趋势；各省份的功能水平表现为阶梯式分布，但能力水平整体差异不大；各地市的经济高质量发展水平存在不同程度的向上或向下转移态势。研究结论有助于统筹推进长三角地区经济高质量发展，为推动共同富裕的实现提供经验证据。

Common prosperity is the essential requirement of socialism with Chinese characteristics,and high-quality economic development is a solid material foundation for realizing common prosperity.It is of great significance to objectively reflect the achievements of highquality economic development from the perspective of common prosperity. Combining the classical feasible capacity theory with the new development concept,this paper constructs an evaluation index system of high-quality economic development including two dimensions of function and capacity. Taking the release time of the five-year plan as the characteristic time point to analyze the changes in the stage of highquality economic development,this paper deeply analyzes the level of high-quality economic development in the Yangtze River Delta region from the dimensions of time,space and region. The results show that the level of high-quality economic development in the Yangtze River Delta region shows a fluctuating upward trend from 2006 to 2021. The functional level of each region shows a stepwise distribution,but the overall difference of the ability level is not large;There are different degrees of upward or downward transfer in the level of high-quality economic development in various cities. The research conclusions of this paper are helpful to promote the high-quality economic development and construction of the Yangtze River Delta as a whole,and provide empirical evidence for promoting the realization of common prosperity.
