新能源汽车产业商业模式创新多要素联动机制研究 ———基于创新生态系统视角

基于创新生态系统理论和种群关系理论,将我国新能源汽车产业上市公司划分为不同生态位 企业种群。 运用模糊集定性比较分析法,从资源基础、企业家精神、技术创新、激励水平和环境动态性 5 个维度出发,探究不同生态位新能源汽车企业种群商业模式创新的联动机制。 研究结果表明:低生态位 企业种群存在“技术创新-激励水平”“技术创新-环境动态性”两种高水平商业模式创新联动机制;中生 态位企业种群主要通过内部资源基础和企业家精神驱动来实现商业模式创新发展;高生态位企业种群存 在“企业家精神-环境动态性”“企业家精神”“激励水平-环境动态性”三种商业模式要素联动机制。     

Energy conservation through resource-aware movement in heterogeneous mobile ad hoc networks

Energy conservation in mobile ad hoc networks is of paramount importance because most mobile nodes usually have very limited energy supply. Previous research on this issue focused on the design at the network or MAC or physical layer. In this paper, we study this problem from the new perspective of node mobility, i.e., analyzing the impact of node movement on energy conservation. In particular, armed with the inherent resource heterogeneity in mobile ad hoc networks, we propose a novel resource-aware movement strategy to make better use of some powerful nodes to achieve energy conservation. We also formulate the resource-aware movement as a NP-complete distance-constrained least-cost (DCLC) routing problem and propose an efficient heuristic solution. Extensive simulations have been used to demonstrate the effectiveness of the proposed schemes.     

两阶段供应链中三种定价方式研究

本文考虑渠道一体化对品牌建设的作用,在一个制造商和两个零售商的两阶段供应链系统中,其中确定性的市场需求与产品的市场零售价格有关,通过分析以下三种定价方式下的最优定价和库存策略下供应链成员和系统的收益,1)商品市场零售价格由零售商各自决定,两零售商和制造商之间存在着竞争活动;2)商品市场零售价格由制造商统一制定;3)市场零售价格、转让价格和系统库存水平按渠道协调的最优原则确定,确定了同一产品品牌内部的市场竞争、定价控制权及转让价格对渠道性能及品牌自身造成的影响,并由此提出了分散决策系统中的一种激励机制.

新能源汽车新时代新征程:2017回顾及未来展望

随着补贴退坡和双积分等重要政策接连出台,中国新能源汽车发展进入新时代。2017年,私人购买量大幅上升到41%,汽车动力电池行业集中度上升,三元电池装机占比显著增加到44%,车桩比有所下降。双积分政策在2017年正式出台,加上国家和地方补贴的进一步退坡,新能源汽车产业加速从政策驱动过渡为市场驱动阶段。但私人消费需求还有待进一步激发,电池等关键零部件的核心技术仍需突破,充电设施的建设与运营面临挑战。双积分和补贴退坡等重要政策实施后,中国汽车行业格局将发生深刻变化。从政策支持与行业发展来看,燃料电池汽车及电动汽车智能化融合发展将是今后重要的发展方向。     

高职班主任队伍建设现状与对策

在广泛调研的基础上,对高职班主任队伍建设现状进行了分析,认为目前高职班主任队伍结构整体趋向合理、制度基本健全,但班主任工作职责不够明确,理论素养尚显不足,激励机制亟待完善。针对这些制约班主任工作开展的瓶颈因素,必须采取相应对策。     

How to Evaluate Government Performance while Building a Rule of Law Government in China*

Building a law-based government is a central element of the comprehensive framework for promoting the rule of law in China, while using evaluation to catalyze growth is in line with the incentive principle of management studies. Since China started to implement reform and opening up over thirty years ago, rule of law development and organizational evaluation have gone through several stages, each with different characteristics. Efforts to build a law-based government have met with success, but what the country now has is essentially still goal-oriented assessment. At present, this suffers from the lack of a clear goal orientation or definition of functions, an imperfect technical system and unsound motivation mechanisms, not to mention the practical problems of each government department going its own way, duplicating evaluations or being left rudderless. Drawing on a combination of value rationality and instrumental rationality and using government performance evaluation to promote the building of a law-based government not only conforms to the spirit of the rule of law and value rationality in government performance, but also strengthens the role of evaluation as an instrument for organizational management. Therefore, we need to create new evaluation theories, expand public participation, introducing diversified evaluating entities, improve technical systems, strengthen institutional buildup, and foster a performance-based culture. In addition, replacing goal-oriented assessment with performance evaluation will help the emergence of a new discipline—the performance evaluation of rule of law government, thus promoting multidisciplinary efforts to integrate and create new public administration theories in China.     

IRENA as a glocal actor: pathways towards energy governmentality

For decades renewable energy has remained a “blind spot” within the sphere of international energy governance. The existing institutional network is highly fragmented, resulting in a myriad of international organizations, which all claim to deal with energy issues, yet do not focus on renewables on a global scale. Since 2009, IRENA, the International Renewable Energy Agency, seeks to fill up this vacuum, thereby creating a new (and maybe more Southern-led) political arena for governing renewable energy issues. This article focuses on IRENA’s role as a changemaker in the sphere of global energy governance by investigating IRENA’s governance practices and contributions to knowledge production.     

园林专业实验课程的项目式模块化构建及教学实践

在对国内外课程模式进行研究的基础上,按照项目式模块化课程构建的基本思路,对园林专业课程中实验内容进行了调整和重新构建,并对部分课程内容进行了教学实践。教学实践充分证明:该课程教学激发了学生主动学习的积极性,满足了相似专业不同培养目标及培养方向的学生对实验课程的不同需要,对学生的考查评价更为科学合理;同时在课程构建的过程也推动了学校的教学改革和实验室建设。
