Aiming at the problem of insufficient accuracy of night lighting data used to estimate urban power consumption, a Boston luminous model is proposed. 176 cities in mainland China was selected as the research area, the NPP-VIIRS night lighting products in 2019 were taken as the data source, the tertiary industry was taken as the classification basis of the Boston matrix, and the research area cities were divided into four categories: star cities, Taurus cities, question mark cities and thin dog cities, and then the whole society electricity consumption was estimated . The estimation results show that this model is more accurate than the traditional lighting model. According to the size of the relative error, all cities are divided into three types: high-precision, medium-precision and low-precision cities. The number of high-precision and medium-precision cities in the Boston luminous model is more than that of the traditional lighting model, while the number of low-precision cities is the same.
