【摘要】 城市群内生动力是城市群发展的内在根本动力。基于内生增长理论，通过熵值法、自然断点法、核密度分析法和Dagum基尼系数，对2005—2021年中国19个城市群内生动力水平的时空演变特征、水平差异及其差异来源进行分析，并借助耦合协调度模型对各地区指标的耦合协调状况进行评估。结果表明：中国各城市群内生动力水平明显提升，区域发展潜力与动能显著提升；内生动力水平呈现“东强西弱，南高北低”的空间特征，且东部地区>中部地区>东北地区>西部地区；城市群内生动力水平总体差异呈现扩大趋势，城市群组间差异是整体差异拉大的主要原因；城市群内生动力水平的不同维度指标发展趋于协调，相较于全国耦合协调度水平，西部和东北地区城市群内生动力水平的耦合协调度有待进一步提升。更多还原

【Abstract】 The endogenous driving force of urban agglomerations constitutes the fundamental driver of their development. Based on endogenous growth theory, this paper uses the entropy method, natural breakpoint classification, kernel density analysis, and the Dagum Gini coefficient to analyze the spatiotemporal evolution characteristics, hierarchical disparities and underlying sources of endogenous driving force of China’s 19 major urban agglomerations from 2005 to 2021. Furthermore, we used the coupling coordination model to evaluate the coordinated coupling status of multidimensional indicators in different regions. The results show that the endogenous driving force of China’s urban agglomerations has been significantly enhanced, with notable improvements in both regional development potential and growth momentum; the endogenous driving force exhibits a spatial pattern of being strong in the east, weak in the west, high in the south and low in the north, with eastern region > central region > northeastern region >western region; the overall disparity in endogenous driving force within urban agglomerations show a steady upward trend, with inter-group differences being the primary driver of this overall divergence; the various dimension indicators reflecting the endogenous driving force levels within urban agglomerations tends to be coordinated development; however, compared with the national average level of coupling coordination, the coordination degree of relevant indicators in western and northeastern urban agglomerations still needs further improvement.更多还原
