Frontier research primarily focuses on the effect of urban development models land use efficiency, while ignoring new-type green efficiency. Accordingly, this paper employs a super efficiency slacks-based measure (super-SBM) model with undesirable outputs to based panel data from 152 prefecture-level cities for period 2004–2017. We construct difference-in-differences (DID) in test impact smart ...

Taking the panel data of 13 provinces (autonomous regions and municipalities directly under central government) in Shanxi Xinjiang from 2011 to 2020 as research object, we establish an evaluation index system for assessing smart mine construction development efficiency combined with global reference method. The non-desired output super-efficiency slacks-based measure kernel density model were u...

The digital economy is considered a driving force of green economic development. However, only few studies have examined the relationship between and total factor productivity (GTFP). According to principal component method super-efficient Slacks-based measure model, level GTFP were measured for China’s provinces based on panel data from 2013 2019. spatial econometric model was then used analyz...

Investigating urban green innovation efficiency (UGIE) is imperative because it correlated with the development of an ecological civilization and innovative country. Spatiotemporal evolution influencing factors UGIE are two important scientific problems that worth exploring. This study presents indicator system for includes input, expected output, unexpected employs a super-efficiency slacks-ba...

Improving the coupling coordination degree between water and land resources matching (WLRM) cultivated use eco-efficiency (CLUE) is crucial to ensuring national food security constructing an ecological civilization. This study based on data of 71 prefecture-level cities in major grain-producing areas middle lower reaches Yangtze River from 2008 2020. The unit area resource method, slacks-based ...
