Does living alone increase the consumption of social resources?

China's living arrangement has changed as the economy grows and society makes progress. More and more people prefer to live alone. In 2018, a total of 240 million people chose to live alone in China, with an annual growth of 0.53% per year. How will the growing number of people living alone affect the resources consumption and the ecological environment? Based on the data from 1998 to 2017 at provincial level, this paper selects domestic water and electricity consumption to represent resources consumption, and household garbage generation to represent ecological environment, taking the proportion of single-person households in the total households as the explanatory variable and age, education, and household appliances as the control variables. This paper aims to apply dynamic panel models to analyze the impact of solitary population on resources consumption (water and electricity resources as representatives) and on waste generation. The results show that (1) people living alone consume more resources and generate more garbage, while household waste is influenced most, followed by household electricity consumption and household water consumption, (2) positive relations between age and resources consumption and waste generation have been identified, and (3) the energy-saving technology of home appliances is conducive to resources conservation and emission reduction.
