In order to explore how to realize the scientific development of construction land, taking 103 counties units in Jiangsu Province as the research objects, based on the land change survey data in 2017, using weighted sum, entropy weight TOPSIS and fuzzy comprehensive evaluation method, we constructed an evaluation index system from three aspects of construction land development degree, development benefit and development potential, and analyzed the coordination degree among the three by using the coupling coordination degree model. The results show that:(1)the spatial differences of construction land development degree, benefit and potential in Jiangsu Province are significant; the comprehensive index of land development in southern Jiangsu Province is the highest, followed by the middle of Jiangsu Province, but the northern Jiangsu Province is generally low;(2)the construction land development in 103 county units in Jiangsu Province belongs to the state of collaborative evolution; the coupling coordination index of construction development degree, benefit and potential is high; the index shows the spatial differentiation pattern of decreasing from south to north;(3)the coordination between the two is quite different; the coordination between the development benefit and development potential of construction land is the best, while the coordination between the development degree and the development benefit, the development degree and the development potential is slightly weak; the spatial differentiation characteristics of coupling coordination between the two are relatively consistent with the overall coordination distribution. In conclusion, the development situation of construction land in Jiangsu Province from good to bad levels is in the order: southern Jiangsu Province > middle of Jiangsu Province > northern Jiangsu Province. We should adjust the land planning policy according to local conditions, so as to provide scientific reference for optimizing the land spatial pattern by referring to the current situation of construction land development and the evaluation results of its own development potential.
