Abstract: As one of the important sources of nitrogen pollution in cities, food consumption has major ramifications for the global nitrogen cycle, making researches about food nitrogen and its urban optimization management of great significance. Taking Beijing as an example, we analyzed the differences in urban and rural characteristics of residents' food nitrogen consumption on the time scale from 1979 to 2019, then used the logarithmic mean divisia index (LMDI) to construct a brand-new factor decomposition model and identify the driving factors. The results showed that overall food nitrogen consumption in Beijing exhibited an increasing trend, from 37 Gg in 1979 to 70.77 Gg in 2019. Rural and urban residents showed the same direction of changing dietary habits, switching to a high nitrogen animal consumption pattern. GDP per capita was the most critical pulling factor, followed by the population. On the other hand, the factors that always showed inhibition are food price level and Engel's coefficient. The results provide a scientific reference for the coordinated development of urban and rural areas and urban nitrogen management and a scientific basis for residents to reasonably plan their food nitrogen input.
