Transportation rates and plant location in oligopolistic competition with sequential entry

This paper examines the impact of quantity-discounted transportation rates on location patterns of oligopolistic competition with sequential entry. When transportation rates are constant, Hwang and Mai (1990) show that the entrant locates at the same point as the existing firms if the production function exhibits constant returns to scale. The entrant will locate farther away from (closer to) the market than the existing firms do if the production function exhibits increasing (decreasing) returns to scale. This paper shows that Hwang and Mai's results need not hold when transportation rates are a function of quantity shipped and distance traveled.

出口经验能助推对外直接投资吗?--基于中国与“一带一路”沿线国家宏观数据的实证研究

以"一带一路"沿线45国2003~2014年数据为样本,实证检验了出口经验能否提升对外直接投资。研究结果显示,出口经验显著提升中国对"一带一路"沿线国家的直接投资。在基准模型的基础上,引入公共治理、能源禀赋和地理区位与出口经验交互项的实证结果还显示,出口经验对直接投资的促进效应随着东道国治理水平提升而提高,对陆上丝绸之路国家的作用显著低于海上丝绸之路国家,而能源禀赋并未直接或间接通过出口经验对直接投资产生作用。这些研究结论说明,企业在不确定性外部环境下进行对外直接投资时,倾向于通过建立出口学习曲线并依此进行直接投资决策。     

Making the next move: When does the newness of experience matter in overseas sequential entries of multinational companies?

Traditional internationalization models suggest multinational companies (MNCs) can exploit their accumulative experience to facilitate their sequential entries. However, experience may depreciate over time. Thus, obtaining benefits from prior experience for MNCs is based on two critical premises, i.e., interpreting and applying experience correctly. We argue that there is a need to study the newness dimension of experiential learning. In doing so, we aim to explore to what extent the newness of experience matters in overseas sequential entries for MNCs. Moreover, we expect that the benefits from recent experience in guiding sequential entries are contingent on the extent of context similarity between the most recent entry location and sequential entry location and the outcome expectancy of focal entry. With a sample of 112 Chinese listed firms and 410 observations during the period of 2000–2012, we find that else being equal, the newness of experience of MNCs is positively associated with sequential entry and such a relationship is positively moderated both by context similarity in institutional environment and the outcome expectancy of the focal entry. We also compare the effects of the newness of different types of experience and find that the newness of the most recent experience has a larger influence on sequential entry than location-specific experience and general experience.

我国的企业正面临着严峻的挑战,除了具有与世界上别的公司相同的因素外,还包括许多我国市场经济转型体制下所特有的因素。在这种情况下,企业所需要的不是一般的CFO,而是高素质、高水平的 CFO,他们既要具备与世界接轨的先进的财务金融知识和技能,还要充分了解我国的国情。     

2D机载雷达目标定位精度分析

对于2D机载雷达,由于缺乏准确的俯仰角信息,无法准确定位地面目标。针对该问题,给出了机载雷达目标定位的数学模型,分析了影响机载雷达目标定位的各种因素,计算了定位的几何精度因子(GDOP),通过仿真,得到了各误差因素综合影响下目标定位精度结果。目标定位精度分析为雷达系统设计,特别是雷达目标如何在数字地图下对目标进行准确定位提供了理论依据。     

中国文化产业发展的区域特征与成因研究——基于第五次和第六次人口普查数据

利用第五次和第六次人口普查数据探讨了中国31省市区文化产业发展的区域特征及其影响因素.对31省市区文化产业就业人数的分析表明,进入新世纪以来,文化产业发展呈显著不平衡,主要表现在行业间发展不平衡和空间分布上不平衡.计量检验显示,地区生活质量、开放度、人口密度和区位条件都是影响中国文化产业区域发展差异的重要因素,但影响传统文化产业和新兴文化产业发展的主要因素是不同的.今后各地区应着重从优化城市生活质量和增强开放性出发,利用城市化经济和地方化经济形成循环累计因果效应,推动文化产业发展.     

Allocating an advertising budget to international travel markets

Deciding on advertising appropriations is a common problem to all National Tourist Offices. The Austrian National Tourist Office now employs a decision support model allowing for inclusion of managerial judgments. In tourism, like elsewhere, application of standard optimization routines to marketing decision making is straight- forward, once the relationship linking market response to input has been modeled adequately. A tailor-made decision calculus procedure eliciting managerial judgments on the relative importance of the factors determining a receiving country's travel market share provides the weights otherwise inaccessible by objective parameter estimation. A tourism manager thus can evaluate countries as tourism generators and allocate an advertising budget accordingly.
