2Environmental Sustainability of Water Footprint in China' Mainland显示文摘Water footprint(WF)measures human appropriation of water resources for consumptive use of surface and ground water(blue WF)and soil water(green WF)and for assimilating polluted water(grey WF).Questions have been often asked about the exact meaning behind the numbers from WF accounting.However,to date environmental sustainability of WF has never been assessed at the sub-national level over time.This study evaluated the environmental sustainability of blue,green and grey WF for China’s 31 mainland provinces in 2002,2007 and 2012,and identified the unsustainable hotspots.Overall,the total WF increased by 30%between 2002 and 2012.The growth can be attributed to the increase of grey WF because the green and blue WF showed only a slight rise.Among all provinces investigated in 2012,eleven showed unsustainable blue WF(sustainability index SI<0),which were mainly located in the North China Plain.There were 12 provinces that displayed unsustainable green WF,and they were distributed in China’s southern and southeastern areas.The grey WF was not sustainable in approximately two third of provinces(19),which were mainly located in China’s middle and northern regions and Guangdong province.More than half of China’s provinces showed trends of improved SI of green and blue WF from 2002 to 2012.However,the SI of grey WF decreased in almost two third of provinces.Poor levels of WF sustainability were due to water scarcity and pollution,which intensify the degradation of local rivers and ecosystems and make restoration more difficult.The results shed light on the policy making needed to improve sustainable water management,and ecological restoration of hotspot regions.Junguo Liu Dandan Zhao Ganquan Mao Wenhui Cui He Chena Hong Yang 2020Geography and Sustainability2020,1,1:1

4Greenspace’s value orientations of ecosystem service and socioeconomic service in China显示文摘Background:Natural ecosystems provide necessary services for human beings,including ecosystem service values(ESVs)and socioeconomic service values(SSVs).The value orientations of ESVs and SSVs are mainly related to people’s interaction with nature.This study reclassified greenspace from a perspective of exposed and non-exposed greenspace based on the level of interaction by people and greenspace.We applied an expert questionnaire to survey the SSVs value orientations of forestland,grassland,wetland,and water bodies,and quantitatively compared the value orientations between the ESVs and SSVs of greenspace in China.Result:(1)The values of exposed greenspace were relatively far higher than nonexposed greenspace,as it had both ESVs and SSVs.(2)The forestland and grassland had relatively high ESVs and SSVs,and are the priority for both the exposed and non-exposed greenspace.(3)Wetland had relatively high ESVs but low SSVs,which was unpopular for exposed greenspace.(4)The ESVs and SSVs of water body were relatively balanced.Conclusion:Greenspace had both ESVs and SSVs when they are exposed to human.Our study provided an innovative perspective to explore the value orientations of greenspace,which provides an actionable scientific basis for greenspace planning,design and construction in human habitat.Xia Yao Tao Lin Shoukai Sun Guoqin Zhang Hao Zhou Laurence Jones Wenhui Liu Yiyi Huang Meixia Lin Junmao Zhang Yuan Chena Hong Ye 2022Ecosystem Health and Sustainability2022,8,1:1

6Sustainable growth research–A study on the telecom operators in China显示文摘In recent years,the telecom industry has faced digital transformation challenges and fierce market competition.The challenges push telecom operators to grow their subscriber bases by offering lower prices and improved services and new features,which puts pressure on operators’profitability.In addition,the rise of Internet companies gradually erodes the profit of the traditional telecom operators.Therefore,paying attention to the critical factors impacting firm sustainable growth can help operators get out of the predicament.Based on the resource-based view(RBV),this study explores the factors that influence the firm sustainable growth.Multiple regression model is applied to empirically test the hypotheses with longitudinal time-series panel data from major telecom operators in China.The study provides empirical evidence for sustainable growth research and useful insights for practitioners on the way to keep sustainable growth.Hong Chena Ling Li Yong Chen 2022Journal of Management Analytics2022,9,1:0
