Abstract
The issue of construction waste reduction has become a global focus, and analyzing the spatial and temporal distribution pattern of construction waste production and the influencing factors is of great significance for different regions to adopt scientific and effective reduction measures according to their own development characteristics. In this paper, panel data of 31 provinces in China are selected from 2013 to 2021 to present the spatial and temporal evolution pattern of construction waste production, and the spatial lag model (SLM) is used to analyze the influencing factors and effects of construction waste production from the perspective of economic and social development. It aims to explore the optimization measures and promotion strategies for construction waste reduction, and to provide reference and assistance for the global construction waste reduction cause. The study shows that China's construction waste production is mainly clustered in the eastern coastal area, with obvious spatial autocorrelation, and the clustering effect shows a trend of rising and then falling, with the peak point appearing in 2018. In terms of the influence effect, the demographic and affluence factors have a more obvious impact on construction waste production than the technological factors. There is a clear spatial spillover effect in the influence of all three aspects on construction waste production, in which urbanization, the scale of the construction industry, the per capita consumption level, the population size and the gross domestic product per capita are the main reasons for the spatial aggregation of construction waste production. Among the construction waste reduction strategies, in addition to the improvement of labor efficiency, the level of technological application, and the requirements of building codes, other strategies need to be considered according to the characteristics and current situation of the socio-economic development of each region. This study is an important reference for countries to analyze the situation of construction waste production and adopt reasonable reduction strategies.
