Abstract In this study, we aim to investigate the long‐term economic consequences of corporate environmental responsibility (CER) by companies from perspective earnings persistence and investors' response. Based on firm‐level data 1,010 heavily polluting listed in China, empirical results are as follows. First, CER China's has significantly improved their persistence, that is, quality. Second, positive effect been achieved through two paths: improving companies' operational efficiency...

Introduction Urban green space is one of the most closely related ecosystem services to residents’ lives, and it can be regarded as a preventive public health measure. Residents living in parks other environments help improve their physical mental health, reduce stress even prevent crime violence. Therefore, based on actual situation China, this paper analyzes relationship between urban middle-aged older adults its mechanisms. Methods This study used multiple linear regression, data from...

Under the urban development trend of sprawl, improving energy use efficiency is a proper way to promote green and low-carbon construction in cities. This paper uses panel data from 283 prefecture-level above cities China 2008 2019 measure sprawl index, analyze spatial-temporal evolution law electricity consumption. The relationship between consumption empirically examined, differential effect on analyzed. Finally, impact based spatial perspective explored depth by establishing error model....

The in-depth discussion and analysis of the synergistic effect new-type urbanization, greening digitalization (NUGD) is important for achievement sustainable social, ecological economic development. Therefore, in this study, an evaluation index system composed these three subsystems was constructed Chinese cities from 2011 to 2021. comprehensive collaborative development levels each subsystem were measured by means including entropy weight method coupling coordination model, respectively....

Abstract Fractionation of proteins by ultrafiltration is an interesting challenge. With a particular membrane, the protein – and membrane interactions largely decide which passes through retained. System hydrodynamics also affects fractionation as transmission behavior altered concentration polarization. Therefore, disruption polarization layer would help to maintain native selectivity hence aid in fractionation. An attempt made use gas sparging, technique proven effective controlling...

Land use change affects the supply and demand of water, energy food integration land elements into common water-energy-food (WEF) nexus, which is an effective way to strictly adhere bottom line natural resources. First, this study used entropy method coupling coordination model measure degree water-energy-land-food (WELF) nexus in 30 provinces China during period 2006–2019. Then, regional differences distribution dynamics were examined with Dagum Gini coefficient Kernel density estimation,...

Introduction Pollution reduction, carbon green expansion and economic growth—the synergistic effects of the four—have become essential in maintaining urban ecological security promoting a low-carbon transition. And it is inherently consistent with globally accepted concept sustainable development. Methods Based on evaluation index system coupling mechanism four, we adopt entropy method coordination model to measure level “pollution growth” 243 cities above prefecture China from 2005 2020....

Exploring the effect of new-type urbanization (NTU) on urban carbon abatement is great practical significance for promoting green construction and coping with challenge global climate change. This study used data from 250 cities in China 2008 to 2020 constructed NTU evaluation indicator system five dimensions. We classical panel regression models examine effects CO2 emissions, further spatial econometric SEM, SAR, SDM identify spillover emissions. The main results are that China’s emissions...

Summary Coverage is one of the basic problems that any wireless sensor network application must solve properly to achieve expected quality service. The communication distance nodes limited, initial energy low, and many optimization objectives need be considered in deployment, which makes deployment very complicated, are difficult. In essence, problem a multidimensional nonlinear with continuous discrete variables. order meet needs monitoring, this article establishes reasonable mathematical...

The continuous progress of industrialization is a fundamental cause China's increasingly severe environmental pollution problem. Improving the efficiency industrial control an inevitable choice to effectively decrease emissions, thus winning battle prevention and control. In this paper, we used stochastic frontier analysis (SFA) model measure provincial based on input output data 29 administrative provinces in China from 2000 2017. On basis, spatial econometric was explore influence...
