Optimizing urban land use is of significant practical importance for promoting economic development, enhancing the standard living individuals residing in metropolitan areas, infrastructure and public services, driving transformation upgrading, attaining synchronized progress economy, society, environment. This paper uses super-efficiency SBM model to measure efficiency (ULUE) 13 cities Beijing–Tianjin–Hebei (BTH) agglomeration from 2005 2020 explores spatiotemporal evolution characteristics influencing factors ULUE this using analysis spatial data application geographic detector methods. The results show that (1) 2020, BTH had an initial rise followed by a decline; however, overall score above 1, suggesting effective state; (2) distribution pattern with Beijing as its core was established, exhibiting greater northern region poorer southern region, correlation values between adjacent cities; (3) capital input, labor social welfare, ecological environment are all promote improvement interaction any two explains better than single factor. empirical research can provide useful references improving input–output ratio units further planning policy formulation region.

The Impact of Land Use Efficiency on County-Level PM2.5: Evidence from 1125 Counties in China

Sustainability, Journal Year: 2025, Volume and Issue: 17(6), P. 2682 - 2682

Published: March 18, 2025

With the severe harm caused by high concentrations of PM2.5 pollution to human health and environment, effectively reducing county-level has become an urgent environmental issue. This paper explores potential land use efficiency in mitigating pollution, proposing that improving could be effective approach emissions. Based on balanced panel data from 1125 counties China 2000 2021, this employs a two-way fixed effects model analyze impact further examines mechanism urbanization industrialization. The main findings are as follows: (1) Improvements significantly reduce concentrations. conclusion remains robust after series robustness tests. (2) Enhanced indirectly reduces promoting industrialization processes. (3) suppressive effect is more pronounced non-resource-based cities non-traditional industrial cities. (4) As population density increases, gradually weakens. (5) In regions with higher levels economic development, follows inverted U-shaped curve. study provides theoretical support policy recommendations for optimizing resource allocation, industrialization, formulating targeted policies.

Road to green urbanization: how does urbanization process affect the green land use efficiency

Frontiers in Environmental Science, Journal Year: 2025, Volume and Issue: 13

Published: April 25, 2025

Introduction As the process of urbanization accelerates, high energy consumption, pollution, and low land use efficiency have led to many significant negative impacts on production daily life. Methods In order investigate impact construction green its potential mechanisms, indicators China’s evaluation system are constructed, SBM-GML model is used measure efficiency. Based this, data from 30 provinces in China 2013 2023 test them using fixed effects, mediating effects threshold effects. Results (1) The can directly contribute improvement use. This conclusion remains valid after conducting endogeneity robustness tests. (2) effect shows that increase synergistic industrial agglomeration promote optimization structure, thus indirectly promoting (3) a exists relationship between level economic development efficiency, based process. deepens, role improving gradually strengthens. (4) Heterogeneity analysis reveals has more driving cities eastern China. Discussion paper suggests optimizing allocation resources accelerating terms green. Attention should be given regional differences carbon emissions during urbanization, it essential continuously optimize realized low-carbon model. Special attention paid enhancing emission control underdeveloped regions, nationwide
