山区沟域经济发展中土地支撑能力评价及其响应途径——北京市密云县的实证分析

沟域经济是山区发展的新视角,以密云县沟域数据为基础,针对沟域土地对经济发展、粮食供给和生态 保护所能提供的支撑能力,构建了土地支撑能力定量评价方法,评价了各沟域的土地支撑能力,并与发展需求进行了比较,进而从沟域发展的经验事实中总结出面对土地支撑能力不足的响应途径.结果表明:土地支撑能力在空间上具有明显的非均衡性,各个沟域差异较大,整体存在土地的支撑能力不足,但通过发展沟域经济、优化响应途径,土地支撑能力和发展需求的差距逐步缩小,即土地相对支撑能力逐步得到提升和加强.     

江西省产业部门碳排放特征及减排途径——基于1992-2007年投入产出分析

根据江西省1992—2007年投入产出表,运用投入产出模型,对江西省产业部门直接碳排放强度和完全碳排放强度进行测算和分析。结果表明：产业部门的直接碳排放强度和完全碳排放强度的排序不一致,产业部门的向后关联效应所引发的隐含碳排放影响极大。然后,根据直接碳排放强度和完全碳排放强度对产业部门进行分类,将产业部门划分为高碳排放部门、隐含高碳排放部门和低碳排放部门,并对不同类型产业部门碳排放特征进行分析。在此基础上提出控制高碳排放部门的能源消耗,优化隐含高碳排放部门的中间投入以及合理协调发展低碳排放产业的政策建议,以期为江西省节能减排政策的制定提供决策参考。     

Hub location problems in transportation networks

In this paper we propose a 4-index formulation for the uncapacitated multiple allocation hub location problem tailored for urban transport and liner shipping network design. This formulation is very tight and most of the tractable instances for MIP solvers are optimally solvable at the root node. While the existing state-of-the-art MIP solvers fail to solve even small size instances of problem, our accelerated and efficient primal (Benders) decomposition solves larger ones. In addition, a very efficient greedy heuristic, proven to be capable of obtaining high quality solutions, is proposed. We also introduce fixed cost values for Australian Post (AP) dataset.

Why the Generalized Bass Model leads to odd optimal advertising policies

We show that the optimal advertising strategy under the Generalized Bass Model (GBM) involves beginning at an extremely low level (the lower the better) and then increasing spending throughout the planning period. This strategy remains optimal in the presence of decreasing prices that affect both margins and diffusion speed. We provide a simple explanation for why this happens. We further show that the intuitively appealing patterns of continuous decrease or increase-then-decrease (both with an uptick towards the end) identified in earlier research are also possible as optimal dynamic advertising paths under the GBM structure, but only if the advertising at launch is constrained to be higher than a particular threshold, which we identify. The constraint necessary to generate intuitively appealing strategies lowers overall profits. Therefore, the GBM generates advertising policy recommendations that most marketers would deem odd. This casts doubt on the value of the GBM for normative purposes. Other existing diffusion models are preferred when seeking normative guidance on optimal dynamic advertising policies for new products subject to word of mouth.     

Fostering international brand loyalty through committed and attached relationships

The relationship-building approach, focused on the building of brand-to-consumer relationships conducive to brand loyalty formation, has become an extensively investigated topic in international brand management studies. However, the theoretical development of this approach manifests obvious diversities, causing managerial uncertainty about how to take appropriate strategic actions to put the relationship-building approach to best use. The current study, orchestrating the main concepts derived from three relationship-building paradigms with necessary adaptations and modifications, develops and validates the Relationship-Building for Strategic Brand Management Model. Its most noteworthy contribution lies in the coalescence of pragmatic utilitarianism, emotionalism and social symbolism, orienting the relationship-building approach to correspond to the principle of holistic consumer experience management. As explicated by the model, committed and attached relationships built upon the relationship foundation mirroring the holistic essentiality of holistic consumer experience are convertible into powerful driver of international brand loyalty. The model structure and causal path pattern prove to be applicable to different international product brand categories in different regions. Strategic implications are deduced from the research findings, which the international brand manager may take into consideration to maximize the effectiveness of relationship-building strategies for fostering brand loyalty in the international market.

收益现值法在旅游资产评估中的应用研究

在经济全球化的条件下,资本的流动性越来越强,资本的逐利本能促使投资人常常进行跨国、跨地区的投资,投资的方式也越来越多样化。在旅游资源得到开发或初步有效开发的地区,直接投资新建项目的机会已经不多。收购、转让、控股和租赁是常见的投资方式。运用收益现值法对3个案例中的旅游资产的现值进行评估分析,较客观地反映了这些特定资产或某一类资产的本金化的价格。
