构建师生互控教学机制的研究

改革开放以来,我国高等教育事业获得长足发展,改革取得令人瞩目的成绩。人才培养是高等学校的根本任务,提高教学质量是高校工作永恒的主题。文章认为高校要以教学监督与制度建设为保障,以设立教育教学评估中心为途径,以教育部本科教学评估为契机,在建立健全教学质量监控长效机制方面做了一些有益的探索和尝试。     

Using choice experiments to value catchment and estuary health in Tasmania with individual preference heterogeneity*

Choice experiments (CE) have become widespread as an approach to environmental valuation in both Australia and overseas. However, there are few valuation studies that have addressed natural resource management (NRM) changes in Tasmania. Furthermore, few studies have focussed on the estimation of estuary values. The CE study described in this paper aims to analyse community preferences for NRM options in the George catchment, Tasmania. Catchment health attributes were: the length of native riverside vegetation; the number of rare native animal and plant species in the George catchment; and area of healthy seagrass beds in the Georges Bay, which was used as a measure of estuary condition. Mixed logit models with interactions between socio‐economic variables and the choice attributes were estimated to account for systematic and random taste heterogeneity across respondents. Results reveal considerable variation in preferences towards the attributes and show that value estimates are significantly impacted by the way in which we account for preference heterogeneity. Preference heterogeneity thus needs to be considered when estimating community willingness‐to‐pay for environmental changes. This study further shows little responsiveness to the presented changes in estuary seagrass area.     

Methods and tools for integrated assessment of land use policies on sustainable development in developing countries

For stimulating sustainable development in developing countries, land use patterns and land use changes are considered critical, and therefore effective and efficient land use policies are needed. In this paper we present a methodological framework that has been developed in a joint European and developing countries project (LUPIS – Land Use Policies and Sustainable Development in Developing Countries), to assess the impact of land use policies on sustainable development in developing countries. An illustrative application is presented for a case study in China, where water pollution due to agriculture in Taihu Basin is a major problem.     

我国二元经济与二元意识互动性分析

我国经济的二元性决定社会意识的二元性,两者之间具有互动性的关系。伴随着二元经济向完全现代经 济转化。二元意识也向完全现代意识发展。但在转化过程中,社会意识,尤其是传统意识,或者成为我国经济发展 的障碍性因素;或者渗透到经济运行中,使我国经济的运行具有了某些来自传统意识的特性。     

组织知识、跨部门协调与新产品创新绩效

组织的知识包括顾客知识、竞争者知识、技术知识等不同类型,不同类型的知识在新产品创新过程中起着不同的作用,并且会受到跨部门协调的影响。本研究基于长三角地区143家企业的问卷调查数据,实证考查了不同类型的组织知识是如何影响企业新产品创新绩效的,及跨部门协调在二者关系中的调解作用。结果表明（1）顾客知识对新产品市场表现有显著正向影响,但对新产品创新效率没有显著影响;（2）竞争者知识对新产品创新效率有显著正向影响,但对新产品市场表现没有显著影响;（3）技术知识对新产品市场表现和创新效率都有显著正向影响;（4）跨部门协调正向调解技术知识与创新绩效的关系。研究结果对于企业怎样提升新产品创新绩效具有重要的启示意义。     

社会交往、旅游情境对旅游需求的影响研究--基于春节“黄金周”的实证分析

以往关于消费者需求行为的研究多基于传统经济学框架的设定展开,认为影响消费者旅游需求的主要因素包含收入、目的地吸引力、交通等,普遍忽视了消费过程中的社会交往和具体情境。文章在理论分析的基础上,提出了若干命题,将消费者收入、社会交往和旅游情境等因素纳入旅游消费者需求的模型中,提出了若干研究命题。依据2014年春节“黄金周”旅游需求调研数据,采用排序选择模型验证了相关命题的正确性。计量结果表明,个人经济因素对我国消费者春节“黄金周”旅游需求影响较小,家庭结构、同伴等社会交往因素是影响其旅游需求的重要因素;我国消费者对于春节“黄金周”出游过程中遭遇的拥堵、旅游市场混乱等旅游情境问题具有一定的容忍度,但是,严重供需失衡导致的旅游情境问题依然对其旅游需求产生了显著的影响。     

企业内知识分布不均衡以及由此产生的知识管理要求

企业内知识分布不均衡为知识管理提供了契机.知识管理的目的在于整合企业现有的知识资源,挖掘知识资源的潜力,促进知识资源的成长和创新.知识管理是从企业内知识分布不均衡出发来塑造企业内新的知识分布不均衡结构.     

“一带一路”沿线省域生产性服务业与制造业联动融合关系辨析

选择"一带一路"沿线18个省域生产性服务业与技术或资本密集型装备制造业动态互动关系为研究对象,运用向量自回归(VAR)模型进行4个细分服务业和装备制造业脉冲响应比较研究,探究其双向互促性、行业异质性及长短期差异性。结果表明:二者虽然有长期均衡关系,但是互促作用具有非对称性。装备制造业对生产性服务业发展的总体拉动力强劲。但无论辅助联动式或价值链嵌入式生产性服务,都只是短期助推装备制造业发展,仍难以构成高端服务能力和发挥显著的规模经济效应,其长期匹配及推动作用较小。长期以来,装备制造业对知识密集型服务业需求程度不高,导致装备制造业对其拉动作用不明显,二者互动关联性较弱。不同互动机理及动态匹配方式下细分服务业与装备制造业互动效应差异性显著。装备制造业来自于自身内部的信息变动影响显著。应加强装备制造业创新投资引资、提升装备制造业产业集群创新竞争力、促使生产性服务业高质量发展、提高高层次人才培养引进效率,以促进沿线省域两大产业高层级耦合互动发展。     

Impacts of peer-to-peer accommodation on the hotel industry: Hoteliers’ perspectives

The sharing economy is a new phenomenon that has considerable implications for traditional industries in general and the hospitality sector in particular. Although some recent studies have investigated the effects of sharing economy on the hotel industry, they primarily focused on quantifying its effects which are not exploratory for a phenomenon. This study attempts to achieve two research objectives. First, an exploratory qualitative method via a semi-structured in-depth interview is employed to investigate the impacts of P2P accommodation on the industry from hoteliers’ perspectives in China. Second, the current study provides valuable insights about traditional hotel marketing and operations. A social science perspective is proposed because prior hospitality research, merely in its commercial sense, fails to capture the essence of hospitality. Results indicate that P2P accommodation has effects on the hotel industry in terms of host–guest interactions, product offerings, staff empowerment, and platform collaboration. The study also suggests that the extent to which P2P accommodation impacts the hotel industry is different in terms of hotel star ratings and operating model. P2P accommodation and the hotel industry in China have a supplementary relationship. This study contributes to social studies of the hospitality literature by gaining insights from hotel senior management level. It also has great implications for the hotel marketing and management practices within the sharing context.     

社会互动对规模养殖户环保饲料支付意愿的影响研究*——基于改进的目标导向理论模型分析框架

［目的］通过引入社会互动变量改进目标导向行为理论框架,探讨生猪规模养殖户对环保饲料的支付意愿及其影响因素,为完善畜禽养殖污染防治政策提供参考借鉴。［方法］以湖北省生猪规模养殖户为研究对象,应用Heckman两阶段模型,研究规模养殖户对环保饲料的支付意愿。［结果］大多数规模养殖户（8134%）愿意采用环保饲料,且平均意愿支付水平为每头生猪饲料成本的669%（4680元/头）。社会互动中的干群互动、同行互动均能显著提升规模养殖户对环保饲料的支付意愿,但同时同行互动不利于其意愿支付水平的提升。进一步的异质性分析表明,在环保饲料支付意愿决策上,社会互动较少的规模养殖户更容易受到制度规范的约束,而社会互动较多的规模养殖户则更易受到感知养殖热情的影响。［结论］政府部门应加大生态环保宣传力度,并借助多种方式推动规模养殖户进行社会互动; 同时可依据社会互动程度的不同,分别制定相应措施以促进规模养殖户对环保饲料支付意愿的提升。
