(3) Regarding the subsample of the CLDS data, “major cities” refers to large- and medium-sized cities, as well as economically developed cities in the coastal region, including direct-administered municipalities, sub-provincial municipalities, provincial capitals and cities with a high GDP per capita in the coastal provinces. The analytical sample size is 1846 persons. (4) The analytical sample size of the SUNS data is 4366 persons. (5) *p < 0.05, **p < 0.01, ***p < 0.001 (two-tailed test)
