发展浆用竹林 助推竹纸结合

分析了加快浆用竹林建设、发展竹浆造纸的必要性与紧迫性。认为制约我国竹材制浆造纸的主要因素是:竹材原料的结构性矛盾限制了竹材造纸产业的规模扩张;竹材利用的可替代性与制浆造纸的比较不经济性决定了竹材制浆造纸原料供给缺乏保障;竹浆造纸行业资金技术密集性与纤维资源限制性制约了竹浆产业规模及技术水平的提高。提出了加快我国浆用竹林建设、推动竹浆造纸的发展策略,即坚持走项目大型化、技术高端化、原料供应基地化路线。

Taking agricultural technologies to scale: experiences from a vegetable technology dissemination initiative in Tanzania

One of the widely suggested approaches to meet the increasing food demand of a substantially growing world population is sustainable intensification. We present a unique agricultural research and scaling programme in Tanzania, focusing on the key elements necessary for results related to: gender analysis; private sector engagement; social capital; improvement and adaptation; and programme performance monitoring and evaluation. Since 2014, more than 6000 farmers have benefited from either the adaptive research or the scaling component of the programme. Preliminary impact analysis results from six pilot locations indicate that programme participants realized significantly higher yields compared to non-participants. In addition to productivity improvements, introducing resistant and drought-tolerant elite vegetable varieties improved the resilience of the existing farming systems. Finally, considering the needs of both male and female participants had a positive impact on technology adoption rates and reach.     

Introduction to the Special Issue on “The Intersection Between Industrial Organization and Healthcare Economics”

This article introduces the special issue on the intersection between industrial organization and healthcare economics. This intersection has received increasing research interest, growing from 2% of the industrial-organization literature in 1991 to 6% in 2016. We describe the nine included articles, which cover a range of healthcare markets that include hospital services, insurance, and pharmaceuticals.     

Product variety,sourcing complexity,and the bottleneck of coordination

Research summary: This paper studies the coordination burden for firms that pursue variety as their main product strategy. We propose that product variety magnifies the tension between scale economies in production and scope economies in distribution, giving rise to complex sourcing relationships. Sourcing complexity worsens performance and poses a dilemma for organization design: A hierarchical structure with intermediate coordinating units such as sourcing hubs reduces sourcing complexity for downstream distribution but creates bottlenecks at the hubs, hurting performance for both the hubs and downstream distribution. We empirically examine operations data for about 300 distribution centers within a major soft drink bottling company in 2010–2011. Results support our hypotheses, illuminating the source of complexity in multi‐product firms and the challenge for organization design in managing complexity. Managerial summary: This paper uses data for about 300 distribution centers within a major soft drink bottling company to study how a large product variety creates complex sourcing networks. We find that, in addition to poor performance (e.g., increased stockouts), complex sourcing networks can cause challenges for organization design. In particular, the benefits of converting an existing distribution center into a sourcing hub (i.e., reduction in sourcing complexity for downstream distribution) and the costs of doing so (i.e., reduction in performance for both the hubs and downstream distribution) are both real and significant. The design of an efficient sourcing network despite its complexity involves important managerial decisions. Experiences in building and managing such networks can be the basis of a dynamic capability. © 2016 The Authors. Strategic Management Journal published by John Wiley & Sons Ltd.     

FDI对中国房地产业技术效率的影响——基于中国省际房地产业面板数据的实证研究

本文运用随机前沿生产函数模型，基于中国省际1999-2004年房地产业面板数据，计量分析了房地产业FDI对中国房地产业技术效率的影响。研究结果表明：（1）中国房地产业技术效率水平呈稳步增长的趋势，但整体水平偏低，且区域差异显著，东部地区房地产业平均技术效率要高出中西部地区57．7％；（2）FDI对中国房地产业技术效率整体水平的影响统计上不显著，这表明从总体上看FDI对改善中国房地产业技术效率作用不大。（3）FDI对促进东部地区房地产业技术效率增长作用显著，但对中西部房地产业技术效率没有产生实质性的影响。这说明FDI对中国房地产业技术效率的影响具有显著酶区域差异性。
