Exploration of the coupling relationship between urban land development and carbon emission performance is significant for achieving a positive interaction between land development and carbon emission reduction.Taking Jiangsu Province as the research area,this paper constructs and measures the evaluation index system of urban land development in each city from 2003 to 2021,and evaluates its carbon emission performance using a super-efficient SBM model.It analyzes the coupling relationship between urban land development index and carbon emission performance,and identifies the key factors affecting their coordinated development by the means of grey correlation model.The results indicate that:1)From 2003 to 2021,the average urban land development index in Jiangsu Province experienced a process which was first decreasing and then increasing,the gap among cities narrows continuously.2)Jiangsu's average carbon emission performance showed a fluctuating upward trend and presented a spatial distribution pattern that changed from"high in the east of Jiangsu and low in the west of Jiangsu"to a balanced development.3)The coupling coordination degree between urban land development and carbon emission performance showed the fluctuating upward trend from 0.531 in 2003 to 0.642 in 2021,and remained in the coordinated development stage after 2020.In the later stage of the research period,nine cities were in the coordinated development stage,Nanjing,Lianyungang,and Huai'an were in the transitional stage,and Changzhou was in the disorder decline stage.In addition,most of cities were in the coupling coordination states of strong negative decoupling and strong decoupling.4)The impacts of land development scale and economic development on the coupling coordination degree were relatively high,while the influences of land social and ecological development were relatively weak.Based on the impact degree of various indicators of urban land development,it proposes targeted policy recommendations to promote the low-carbon development of urban land.
