粤东西北与珠三角物流产业技术效率比较

运用DEA效率测度方法,通过对2013-2017年粤东西北与珠三角区域物流产业技术效率的对比研究,探索推动广东省区域物流协调发展的路径。结果显示:对比珠三角区域,粤东西北区域物流产业技术效率与珠三角区域存在较大差距,尤其是粤东与粤西地区,粤东区域物流产业技术效率值仅为0.4,粤西区域物流产业技术效率值为0.81,均远低于珠三角区域物流产业技术效率值0.94。纯技术效率低下是制约粤东西北地区物流产业技术效率提升的主要因素,应加强物流产业信息技术应用,推进物流技术装备现代化,提高技术创新能力水平。     

山岭隧道洞口浅层滑坡处治关键技术研究

受地形地质条件、工程经济以及勘察深度等因素的制约,山岭重丘区隧道不可避免地会受到各种不良地质灾害的影响.为解决隧道穿越洞口浅埋段滑坡体的施工安全问题,以乐业至百色高速公路永乐隧道工程为研究背景,针对其地形地质条件及滑坡体情况,结合洞内变形与滑坡体变形相互作用机理,对隧道穿越洞口浅埋段滑坡体施工关键技术进行研究,并针对性地提出"洞外加固处治+洞内严格控制沉降"的综合处治方案.实践结果表明,本隧道工程穿越洞口浅层滑坡体的施工过程安全顺利,采取的施工控制措施方案实施效果良好.     

二战后马克思主义经济学面临的现实性挑战及其回应

时代的发展与变迁对马克思主义经济学提出了新的问题和挑战,对此中外马克思主义经济学者在理论上进行了大量的有价值的研究和探索。从科技革命的推动与资本主义的历史地位、市场经济体制的建立与社会主义的发展、西方经济思潮的冲击与马克思主义经济学主流地位的坚守四个方面,梳理了二战以来中外马克思主义经济学者的研究成果,发现马克思主义经济学的生命力与科学性正是源于在实践中的丰富和发展,因此,坚持马克思主义经济学在中国的指导地位,首先必须在新的时代条件下,与时俱进,创新和发展马克思主义经济学。     

Indigenous Peoples,Resource Extraction and Sustainable Development: An Ethical Approach

Resource extraction companies worldwide are involved with Indigenous peoples. Historically these interactions have been antagonistic, yet there is a growing public expectation for improved ethical performance of resource industries to engage with Indigenous peoples. (Crawley and Sinclair, Journal of Business Ethics 45, 361–373 (2003)) proposed an ethical model for human resource practices with Indigenous peoples in Australian mining companies. This paper expands on this work by re-framing the discussion within the context of sustainable development, extending it to Canada, and generalizing to other resource industries. We argue that it is unethical to sacrifice the viability of Indigenous cultures for industrial resource extraction; it is ethical to engage with indigenous peoples in a manner consistent with their wishes and needs as they perceive them. We apply these ideas to a case study in the coastal temperate rainforest of Clayoquot Sound, British Columbia, Canada. In this case a scientific panel comprised of Nuu-Chah-Nulth elders, forest scientists and management professionals, achieved full consensus on developing sustainable forest practice standards by drawing equally on Indigenous traditional ecological knowledge and Western science in the context of one of the most heated and protracted environmental conflicts in Canadian history. The resulting sustainable forest practice standards were later adopted by leading forestry firms operating on the coast. Our analysis of this scientific panels success provides the basis for advancing an ethical approach to sustainable development with Indigenous peoples. This ethical approach is applicable to companies working in natural resource industries where the territories of Indigenous peoples are involved.David Lertzman Ph.D. is Adjunct Assistant Professor of Environmental Management and Sustainable Development and Senior Associate with the TransCanada International Institute for Resource Industries and Sustainability Studies at the Haskayne School of Business, University of Calgary.

生态足迹与区域生态适度人口——以西部12省市为例

一个区域生态适度人口的确定取决于区域生态承载力与区域人口对生态资源的需求.介绍了生态足迹模型的基本概念和计算方法,并运用该模型对中国西部12省、直辖市、自治区生态适度人口进行了估算.中国目前已经出现过度人口和生态赤字,但在较低社会经济发展水平和低消费的条件下,西部地区具有相对较小的人地矛盾,生态赤字较小,目前的人口规模基本可认为是合理的.随着西部开发的进程,西部省区正在并将持续面临严重的生态压力.     

适用技术:西部地区构建和谐社会的技术基础

科学技术是第一生产力,是人类认识和改造世界的强大武器。和谐是社会主义的本质属性,是国家富强、民族振兴、人民幸福的重要保证。基于西部地区构建和谐社会的特殊性和复杂性,在科学发展观的指导下,西部地区构建和谐社会的技术理念应是发展适用技术。大力发展适用技术,是西部地区构建和谐社会的突破口和必然选择。"恭城模式"、"象州实践"和"和林格尔现象"等都是西部地区通过适用技术,构建和谐社会成功的典范;而"民勤县荒漠化"现象则主要是由于没有采用适用技术导致的。     

西方国家劳动力市场灵活化改革的理论分析

灵活化目前已成为西方国家劳动力市场改革的主要发展趋势。西方国家希望通过放弃凯恩斯主义的劳动就业宏观需求管理政策、减少政府和工会对劳动力市场的管制与干预,以及实行激活性劳动就业政策等措施来降低劳动力市场的刚性,提高就业率。从理论上来讲,劳动力市场灵活化改革的根源在于:凯恩斯主义就业政策的失灵、刚性劳动力市场的低效率和全球化时代生产方式与就业模式的根本性变革。同时,劳动力市场的灵活化也被认为是降低失业率的一条有效途径,也是政府、资本和工会之间新的力量平衡下的一种选择。     

现代农业支撑下西部农村小城镇建设机制设计

产业支撑缺乏、基础设施落后、管理体制缺陷、社会发展薄弱和文化机制冲突是西部地区农村小城镇建设面临的重大制约与严峻挑战。全面推进西部农村城镇化进程必须依托现代农业,通过发展推动小城镇建设并进行崭新的机制设计。战略重点是创新管理体制、优化经济机制、健全社会机制、培育文化机制、发展特色城镇,构建以现代农业发展为基础的西部特色小城镇体系。     

西部大开发的新特点与新机遇

我国西部大开发政策实施几年后,显现出良好的发展势头,近几年又表现出了许多新特点。西部大开发的实施,使西部地区的交通条件、电力等基础产业、城市基础设施、经济体制等软硬环境都得到了改善和提高。而中央在投资、财税、金融、土地、促进东西互动等方面的政策,决定了今后5至15年将成为西部大开发的黄金时期。在此过程中,西部现有和未来的特殊优势产业,如能源及化学工业、重要矿产开发及加工业、特色农牧业及加工业、重大装备制造业、旅游及文化产业、一些高技术产业则蕴藏着更大的商机。
