[Objective]The aims of this study are to reveal the evaluation and development potential of urban land use efficiency, and to provide scientific basis for promoting efficient and intensive use of urban land in the Yangtze River Delta region. [Methods]The Yangtze River Delta region was used as the research object. An SFA model was construct to evaluate urban land use efficiency and calculate land development potential. [Results](1)During the research period, the land use efficiency of cities in the Yangtze River Delta increased year by year, and the efficiency gap between regions increased from 0.357 in 2000 to 0.478 in 2020. In terms of spatial distribution, ‘core periphery' layout features were obvious, and the core cities such as Shanghai, Nanjing and Hangzhou had higher efficiency values. Low value areas were distributed in Nantong, Yangzhou, Zhoushan, Taizhou and other marginal cities in the middle of Jiangsu Province, showing the differentiation feature of ‘large agglomeration and small dispersion'. At the same time, the unbalanced development trend of efficiency layout was significant.(2)The scale of land intensive potential in the Yangtze River Delta had increased year by year, from 1 183.2 km2 in 2000 to 2 590.8 km2 in 2020, while the proportion of land intensive potential had decreased from 66.18% in 2000 to 59.00% in 2020. The scale classification and proportion classification of urban land intensive use showed different rules of change, and revealed the space-time evolution characteristics of land development potential from different perspectives.(3)The scale of potential increase of urban land output had been expanding in the vertical time axis, while the proportion of potential increase of land output in 16 cities had been declining, from 239.91% in 2000 to 171.75% in 2020. Among them, capital investment and labor allocation in Shanghai, Hangzhou and other central cities were relatively reasonable, land use intensity was high, and the proportion of output increase was only 30%. [Conclusion]During the research period, land use efficiency in Yangtze River Delta region had been increasing year by year, and the scale and proportion of land intensive potential had also been continuously increasing, which can provide a practical path for clarifying the connotation of urban economic development, and also provide new methods for efficient use and potential exploration of urban land.
