To construct a measurement model for efficiency morphology of homestead utilization (EMHU) and ecological association morphology (EAM), taking town and village as two research scales, this paper explores the spatial differentiation of EMHU and EAM from three perspectives including policy, resource and location orientation, so as to offer references for the sustainable utilization of homestead resources. Taking 235 villages in Jinghai District, Tianjin as the study case, unexpected output super-efficiency SBM model, ecological environment index and coupling coordination model are adopted. Research results show that: 1) from the perspective of policy guidance, the average EMHU value of characteristic towns is better than that of ordinary towns, and EAM shows the opposite trend. The EMHU and EAM of characteristic towns are mainly concentrated in low levels; the EMHU distribution of general towns is relatively balanced, and the EAM is mainly distributed in high levels. 2) From the perspective of resource orientation, the average EMHU value of industry-led towns is better than that of culture-led towns, and vice versa for EAM. The EMHU of industry-led towns is evenly distributed, with EAM mainly concentrated in low-level areas, and vice versa for culture-led towns. 3) Overall, the EMHU of culture-led towns in characteristic towns is higher than that of industry-led towns in general towns, while in general towns the EAM of medium industry-led towns is the strongest, and the EAM of industry-led towns among characteristic towns is the weakest. 4) From the perspective of village division, the increase in location advantages will cause EMHU and EAM to show a positive U-curve. The trends of EMHU and EAM at different scales and different perspectives are traceable, and show obvious spatial differentiation. Different scales and different perspectives should be considered when promoting the harmonious coexistence of rural life and ecology to realize rural revitalization.
