Research on Marginal Consumption Tendency of Urban Residents in Yangtze River Delta Region

One of the important research matters is the marginal consumption propensity of urban residents. A great many Chinese scholars have investigated the marginal consumption propensity of residents in a single province and city, but there is still a certain gap in the comparative study of marginal consumption tendency among different provinces and cities nationwide. The research theme of this paper is to explore the marginal consumption tendency of urban residents in the Yangtze River Delta region and compare the differences among them. We select the per capita disposable income and per capita consumption expenditure of urban residents in the Yangtze River Delta region from 2004 to 2022, dividing the Yangtze River Delta region into four cities, and calculate the marginal consumption tendency of urban residents in each city by establishing the ELES model. The study found that the marginal consumption tendency of food and housing has become the highest value of urban residents in each region, reflecting people's attention to food and continuous pursuit of improving living experience. And in the case of different cities in the Yangtze River Delta region, there is a relatively distinct difference in the marginal consumption propensity of residents.
