Measuring benefits from spatially-explicit surface water quality improvements: The roles of distance,scope, scale,and size

Programs to improve water quality do not improve all water bodies equally. Evaluation of the benefits of such programs must account for where improvements occur and the relative magnitude of improvements that occur in different places. This study uses a choice experiment survey to explore how the value to a household of a surface water quality improvement varies as a function of (i) the distance between the household and the affected streams and rivers, (ii) the degree to which the quality of the water has been improved, (iii) how many stream and river miles have been improved, and (iv) the sizes of the affected streams and rivers. Results show evidence that value declines with distance in an approximately linear way, weak evidence that large rivers are worth more than small rivers, and no evidence that willingness-to-pay is nonlinear in either the degree of water quality improvement or the number of stream miles improved. These results indicate that it may be defensible in applied work to value small, spatially-explicit water quality improvement projects independently and then sum over projects.

Large agricultural investments in Kenya’s Nanyuki Area: Inventory and analysis of business models

Many experts agree that more agricultural investment is needed in the global South to improve local food security and reduce poverty. However, there is a lack of consensus about the types of investment needed to achieve these goals. This paper contributes to the literature on large agricultural investments and corresponding business models by inventorying and analysing such investments in Kenya’s Nanyuki area. We identify four clusters of business models that differ primarily by type of production and other distinct determinants, namely: demand from markets; access to land; land tenure regime and colonial history; actors involved; biophysical context; labour availability; and governance of the value chain via private standards. The study results shed light on the factors that help or hinder implementation of large agricultural investments and shape their impacts in the context of African land use systems. The way land is accessed represents one of the most-decisive factors determining the risks and opportunities associated with such projects. We find that most investments in the Nanyuki area occur on land bought or leased from private owners.     

Circular business model implementation: A capability development case study from the manufacturing industry

Circular business models (CBMs) have huge potential to deliver economic, social, and environmental benefits, but CBMs have yet to be implemented widely in industrial settings. One reason is that they are often presented as one-size-fits-all solutions, but this is misplaced because product-specific criteria and company capabilities determine the correct choice and implementation of CBMs. Therefore, the purpose of this paper is to investigate how CBM selection and capability development facilitates the implementation of CBMs. For this purpose, we have adopted a qualitative research approach and undertaken 25 explorative interviews in three large Swedish manufacturing companies. In this paper, a CBM implementation framework consisting of two parts has been developed. The first part addresses the choice of the appropriate CBM based on tactical configurations. The second part provides a capability development path by explicating underlying routines that need to be progressively developed in order to move smoothly to more advanced CBMs.     

我国物流业2019年发展回顾与2020年展望

2019年是中华人民共和国成立70周年,也是物流业稳中有进、变中求新的一年。面对严峻形势,我国物流业顶住下行压力,实现平稳运行,取得多方面进展。具体而言,一是社会物流需求增速持续放缓,总体运行缓中趋稳;二是物流需求结构持续优化,物流供给结构稳步升级,供需结构加速调整;三是科技应用引领数智化转型,科技赋能物流数智化、平台化;四是新兴的供应链服务企业向标准化发展迈出了重要一步,供应链创新发展进入新阶段,现代供应链成为新亮点;五是物流基础设施网络加快升级,物流枢纽网络建设进入实质推进阶段,助力枢纽经济发展;六是物流业"走出去"空间加大,国际物流打开对外开放新局面,我国对外投资合作与对外援助执行保持平稳有序健康发展;七是绿色物流配合污染防治攻坚战,绿色可持续物流取得新进展;八是物流政策落地,物流企业获得感增强,从业人员稳定性增强,物流营商环境持续改善。2020年,我国经济稳中向好的基本趋势不会改变,物流业平稳增长的总体方向不会改变,物流业主要经济指标将继续保持平稳增长,但物流业下行压力依然较大,发展不平衡、不充分矛盾依然比较突出,与人民群众日益增长的美好生活需要和现代化经济体系建设的要求相比依然存在差距,高质量发展任重道远。在新的一年里,为更好地推动我国物流业发展,一要平衡物流稳增长与高质量发展关系,决胜全面建成小康社会;二要坚持目标导向,探索新时代物流业发展的新使命新要求;三要突出新发展理念,推动传统数量型降成本向效率型降成本转变;四要深化产业联动融合,从低水平粗放式发展向精细化、高品质发展转变;五要坚持科技引领和技术驱动,激发物流业高质量发展新动能;六要推进国家物流枢纽联盟工程和全国百家骨干物流园区互联互通工程,建设物流基础设施网络;七要配合"一带一路"倡议,推动国际物流合作与交流;八要进一步处理好政府与市场、国家与地方、市场与企业的关系,营造政府、企业与协会合力推动物流业高质量发展的产业生态圈。     

Factors influencing consumers' purchase decision-making in O2O business model: Evidence from consumers' overall evaluation

Online-to-offline (O2O) has become a rapidly growing e-commerce model worldwide, but the factors influencing consumers' purchase decision-making have not been examined well. After exploring the working mechanism of the O2O model, we extract eleven indexes of consumers' overall evaluation in the O2O model with Crawlzilla and R techniques. Social network analysis (SNA) is adopted to build social networks reflecting consumers' overall evaluation in the O2O model. Based on the modified social network and the extracted subgraph, this study (N = 768) reveals consumers' overall evaluation behavior patterns in the O2O model by calculating network density, central potential, edge betweenness. The results show that shoppers overall evaluate the eleven indexes, especially perceived product quality, online product price, promotion intensity, business reputation, and product brand, which reflects the significant associations between the indexes. Among all the eleven evaluation indexes, perceived product quality, online product price, and business reputation dominate consumers’ decision-making behavior. When making purchase decisions, consumers not only overall consider online product price, perceived product quality, and business reputation but also balance perceived product quality, business reputation, and promotion intensity. Finally, we make some suggestions on marketing strategy for e-commerce companies.     

Systemic circular business model application at the company,supply chain and society levels—A view into circular economy native and adopter companies

This study contributes to the conceptualization of a sustainable circular business model (CBM), the application of the circular economy (CE) by companies. The study utilized a three-level framework adapted from the CE literature with company (micro), supply chain (meso) and society (macro) levels. This multiple-case study in the textile industry included two types of companies operating in the CE: companies founded on the sustainable principles of a CE (natives) and companies transitioning to a CE from the linear economy (adopters). The findings show that the adopters emphasized long-term economic sustainability on a company level and implemented CE elements to varying degrees on all three levels. The natives pursued business decisions from environmental and social sustainability standpoints, and the three levels were integral in their systemic approach to a CE. The study highlights two key claims: established operational structures and economic volition hindered adopters in their systemic CE implementation, and an integral part of the CBM for natives was a proactive approach towards the society level.
