“…The existing research studies on reducing waste from the source are mainly based on the influencing factors of domestic waste production in single or multiple provinces, including population size, population density, the per capita consumption expenditure, share of tertiary industry, gas permeability, investment in urban appearance and environmental sanitation, etc. The researchers consistently find out that gas permeability and investment in urban appearance and environmental sanitation have a negative impact on the domestic waste production (Xu et al 2019, Huangfu and Li 2018, Wang et al 2020a, while other factors have a positive one (Nicolli and Lafolla 2012, Xu et al 2013, Drew et al 2013, Han et al 2018). However, for per capita GDP, which is one of the important factors, most scholars find out that it has nonlinear relationship with the domestic waste production, but there is a dispute on what a nonlinear relationship it is.…”

Since the implementation of the compulsory sorting of domestic waste policy in China, the participation rate of residents is low, which leads to the unsatisfactory result of terminal reduction of domestic waste. Therefore, the problem of domestic waste reduction still needs to rely on source reduction. Based on the panel data of 29 provincial capitals in China from 2009 to 2018, this study conducts a comprehensive threshold effect test on per capita GDP and other influencing factors of domestic waste production, conducts panel threshold regression for the factors with threshold value, and explores the nonlinear relationship between per capita GDP and domestic waste production under the influence of different threshold variables. The results show that when the urban population density is less than 272 people/km 2 , the increase of 1% of per capita GDP will lead to a decrease of 0.251% in the domestic waste production, otherwise, it will lead to an increase of 0.249%; when the per capita consumption expenditure is less than the threshold value of 10,260 yuan/year, the influence coefficient of per capita GDP is 0.155, which increases to 0.207 above the threshold. When the share of tertiary industry is taken as the threshold variable, the two threshold values are 61% and 71% respectively. Through the analysis of control variables, it has been found that population size and amount of courier per capita have significant positive effects on domestic waste production, while gas permeability and the number of non-governmental organizations have significant negative effects.
