要素结构与技术进步方向——来自中国城市“撤县设区”的证据

本文基于1997—2010年267个地级及以上城市市辖区面板数据，运用标准化供给面系统方法测算了市级层面的技术进步方向，并借助“撤县设区”这一自然实验，利用工具变量法实证检验了要素结构变动对技术进步方向的影响，研究发现：（1)“撤县设区”使得资本—劳动比上升，进而导致技术进步方向偏向于资本，符合偏向型技术进步的“弱诱导偏向型假说”；（2)“撤县设区”对资本偏向型技术进步的影响是有条件的，主要限于资本—劳动替代弹性大于1即资本—劳动呈替代关系的地区；（3)相比于中西部地区，东部地区资本要素更为丰富，因而“撤县设区”显著提高了东部地区的资本—劳动比，使其技术进步方向偏向资本。     

Are Chinese nationals’ attitudes to wildlife tourist attractions different from those of other nationalities?

Many wildlife tourist attractions (WTAs) have negative impacts on animal welfare and species conservation. In the absence of regulation, raising standards requires tourists to create market pressure by choosing to attend WTAs with benefits for wildlife. We surveyed respondents from five countries – China, Australia, Canada, UK, and USA – to quantify how attitudes to captive animals, and towards WTAs’ outputs and standards, may vary with nationality. Our aim was to provide a firm basis for behaviour change interventions to alter current patterns of tourist consumption of WTAs. All respondents agreed on the importance of conservation and animal welfare, but Chinese respondents were twice as likely to believe that WTAs would not be allowed to exist if they were bad for animals, and that WTAs’ promotional materials were reliable indicators of welfare and conservation standards. These findings indicate Chinese respondents had fundamentally similar attitudes to those from the other countries, but differed in how those attitudes were likely to be applied. Chinese tourists may experience more barriers to aligning their actions with their values with respect to WTAs. Removing these barriers may require information campaigns to highlight the lack of regulation, and the unreliability of some WTAs’ promotional materials and tourists’ reviews.     

Factors affecting agricultural land transfer-in in China: a semiparametric analysis

We use interview survey data collected randomly from 2677 farm households in nine provinces of China to understand the role of demographic, economic, land, and village characteristics on agricultural land transfer-in by farmers. Results show that variables such as borrowing from informal sources, household labour availability, percentage of total income from agricultural sources, and the household with village cadre have significant positive effects on land transfer-in. Low economic development and low transportation network availability in a county reduces land transfer-in. We also find that two variables (land holding and land idling) should be entered into the model nonparametrically. Land holding and land idling have U- and L-shaped impacts on land transfer-in, respectively. Land transfer-in has endowment equilibrium and provides Chinese households more opportunities to earn agricultural income, thereby reducing rural poverty.     

中国海外耕地投资的区位特征及其影响因素*——基于2000—2016年土地矩阵网络数据

［目的］分析中国海外耕地投资的区位特征及其影响因素，以促进我国海外耕地投资的合理布局，提高农业投资效率。［方法］以2000—2016年中国137宗海外耕地投资项目及其所涉及的35个东道国作为研究样本，运用Spearman相关分析方法，分别以耕地投资面积和耕地投资项目数量作因变量，研究其与各影响因素的相关关系，并用对应分析法进一步探究各东道国的相对优势。［结果］（1）我国海外耕地投资区域集中在东南亚且由周边国家向外扩展，被投资耕地用途多样，投资规模自2004年开始急剧上升，近年来呈下降趋势。（2）我国海外耕地投资以效率寻求型和市场寻求型为主，倾向于资源丰富、与我国距离较近、制度相似、经济关系良好但发展水平不高的国家。（3）根据各地区的比较优势，亚洲国家适合效率寻求型和市场寻求型的企业投资，欧洲和美洲国家适合资源寻求型和战略资产寻求型的企业投资，非洲国家适合资源寻求型、效率寻求型和市场寻求型的企业投资。［结论］中国农业企业应结合企业投资目标和各地区的比较优势，合理选择投资区位，适时转变投资策略与模式，积极防范海外耕地投资过程中的自然风险、政治环境风险和道德风险等，以提高投资效果。     

中国耕地资源利用的碳排放时空特征及脱钩效应研究

研究目的:揭示中国耕地资源利用的碳排放时空分异规律及其与农业经济增长之间的脱钩关系,以期为中国耕地资源低碳化利用政策的制定和推行提供参考。研究方法:IPCC碳排系数法,TAPIO脱钩分析法。研究结果:(1)中国耕地资源利用的碳排放整体上呈现增长趋势,但2010年后增速趋于下降并于2016年开始转入负增长,省际差异不断扩大的同时区域间差异趋于缩小;(2)中国耕地资源利用的碳排放强度总体上处于下降态势,省际和区域间碳排放强度的差异总体上趋于缩小;(3)中国耕地资源利用的不同碳排放源的碳排放量及增速呈现不同的时序波动特征,同时存在明显的地域差异性,其中,化肥是最主要碳排放源;(4)中国2000—2012年耕地资源利用的碳排放与农业经济增长之间呈现以"弱脱钩"为主,但2013—2017年不同省域的脱钩类型及脱钩程度趋于差异化。研究结论:中国耕地资源利用碳排放的时空分异性显著,且与农业经济增长之间不同阶段和不同省域呈现不同脱钩类型,需突出减排重点、实施差异化策略及注重绿色发展等多途径推进耕地资源低碳化利用,提高政策的精准性。     

The Doctrine of the Mean: Workplace Relationships and Turnover Intention

The present study examines the curvilinear relationships between LMX/TMX and team members' turnover intention simultaneously. That is, members with high LMX, TMX, or both are more likely to have turnover intention. Hypotheses were tested with a sample of 452 nurses, and we adopted the response surface methodology and polynomial regression to test our theoretical model. The hierarchical regression analysis showed that TMX has a U‐shaped relationship with turnover intention but not with LMX. In addition, the results indicate that both the congruence and incongruence of LMX and TMX result in higher turnover intention, but moderate levels of LMX and TMX have the lowest turnover intention. Strengths, limitations, practical implications, and directions for future research are discussed. Copyright © 2018 ASAC. Published by John Wiley & Sons, Ltd.     

Climate Change and Preparations for the Tide of Traumatic Stress: Implications for Asia-Pacific Human Resources

Although attention to the business risks posed by natural disasters fueled by climate change has grown, the toll that disasters have on human resources in the form of traumatic stress is comparatively neglected. It is common for more than 20% of people exposed to natural disasters to develop traumatic stress disorders that can last for years. In the workplace, traumatic stress hurts attendance, the quantity and quality of output, and relationships. Fortunately, businesses can promote employee resilience and recovery. Given the Asia-Pacific region’s high risk of natural disasters, businesses operating there should include employees’ traumatic stress in their disaster preparedness.     

Then and Now: Examining Older People's Engagement in Outdoor Recreation Across the Life Course

Outdoor recreation provides a range of health and wellbeing benefits and facilitates engagement with natural environments. We explore older people's participation in outdoor recreation throughout their lives to examine how past experiences shape engagement later in life. A qualitative life history approach, consisting of semi-structured interviews and a focus group in three place-specific (urban, rural, and small town coastal) case studies in Scotland, was adopted. Thematic analysis revealed ways in which childhood experiences shaped adult engagement and highlighted life course transitions where behaviour change was most pronounced. Place and gender were considered as factors which may affect responses. Participants identified the points of getting married, becoming a parent, children entering adolescence, retirement, the onset of disabilities or ill health, and the death of others as “moments of change” in the extent and/or form of their outdoor recreation. The findings highlight potential for targeted interventions to promote outdoor recreation throughout life.     

Educational upgrading,structural change and the task composition of jobs in Europe

We analyze the changes in the task content of jobs in 24 European countries between 1998 and 2015. We link the O*NET occupational data with the European Union Labour Force Survey (EU‐LFS), and use the methodology of Acemoglu and Autor ( 2011 ). We find that the intensity of non‐routine cognitive tasks grew in all countries, while the intensity of manual tasks declined. Workforce upskilling was the major factor contributing to these developments. The intensity of routine cognitive tasks grew in most Central and Eastern European countries, but it declined in Western European countries. This difference is attributed to the contrasting patterns of structural changes in these groups of countries.     

Environmental Policy,Sustainable Development,Governance Mechanisms and Environmental Performance

We investigate the effects of environmental policy (Climate Change Act – CCA), sustainable development frameworks (Global Reporting Initiative – GRI; UN Global Compact – UNGC) and corporate governance (CG) mechanisms on environmental performance (carbon reduction initiatives – CRIs; actual carbon performance – GHG emissions) of UK listed firms. We use the generalized method of moments (GMM) estimation technique to analyse data consisting of 2245 UK firm‐year observations over the 2002–2014 period. First, we find that the CCA has a positive effect on CRIs, and this effect is stronger in better‐governed firms. Second, we find that the GRI‐based framework is positively associated with CRIs. Third, we find that firms with poor CG structures have lower actual carbon performance compared with their better‐governed counterparts. Overall, our evidence suggests that firms can symbolically conform to environmental policy (CCA) and sustainable development frameworks (GRI, UNGC) by engaging in CRIs without necessarily improving actual environmental performance (GHG emissions) substantively.
