Diatoms are unicellular, mainly photosynthetic, eukaryotes living within elaborate silicified cell walls and believed to be responsible for around 40% of global primary productivity in the oceans. Their abundance in aquatic ecosystems is such that they have on different occasions been described as the insects, the weeds, or the cancer cells of the ocean. In contrast to higher plants and green a...

Sustainability and, in particular, green sustainability are very complex subjects, because they typically include several integrated sub-systems. Many of these contain dynamically changing objects and variables, which are often difficult to measure and calibrate. Green sustainability means waste reduction and optimization with a non-toxic process focus that can be maintained over time, for a ve...

This study examines the spillover effects of foreign direct investment (FDI) on green technology progress rate (as measured by the green total factor productivity). The analysis utilizes two measures of FDI, labor-based FDI and capital-based FDI, and separately investigates four sets of industry classifications-high/low discharge regulation and high/low emission standard regulation. The results...

The improvement of industrial green TFP is crucial for the sustainability economy and environment. And eco-innovation directly improves TFP. However, there are few studies on relation between Based relevant data from 2006-2015 30 provinces in China, using SBM model this study firstly evaluates each province by measuring desirable output undesirable output. Then measured patent application quant...

There are few studies analysing whether different types of environmental regulation have differential impacts on the efficiency construction industry. Using 2012–2016 panel data from 30 provinces in China, green total factor productivity (GTFP) industry is measured with a global Malmquist–Luenberger index based epsilon measure model. Thereafter, tobit regression model proposed to explore relati...

Lean-Green is a concept that associates value aggregation and efficiency in operational and environmental terms (eco-efficiency). This concept arises as a corollary effect of companies’ challenges for rethinking their goals and strategies in order to add more value while contributing to social equity and prevent environmental burdens. The eco-efficiency concept translates the idea of “creating ...

Abstract This study investigates the impact of digital economy (DE) on green total factor productivity (GTFP) and its transmission mechanism. Using panel data from 256 cities in China 2009 to 2020, examines a directional distance function Malmquist–Luenberger index estimate GTFP growth constructs an ordinary least squares model explore effect Three findings are drawn estimation results: (1) The...
