Starting from the development characteristics of the family service industry, a measurement and evaluation index system was constructed for the high-quality development of the family service industry from five dimensions, which were development, sharing, coordination, sustainability and openness. The entropy weight method was used to measure the high-quality development level of household service industry in the Guanzhong Plain urban agglomeration from 2011 to 2022, and kernel density estimation and spatial Markov chain method were used to explore the dynamic evolution trend of high-quality development of household service industry in the Guanzhong Plain urban agglomeration. It is found that the development trend is steadily increasing, and the overall level of development is low. Balanced development is in the sustainable dimension, with existing regional imbalances. There is a siphon effect in urban agglomerations, and the coordinated development of cities is not significant.
