中国的外资优惠政策应该取消了吗?——基于东道国政府之间FDI竞争的视角

东道国政府之间对FDI的争夺主要在相邻的国家之间进行,且竞争主要集中于效率寻求型FDI中的低技术制成品及中技术和高技术中的简单终端产品。本文对我国与其他国家之间的FDI竞争进行了实证研究,发现中国虽然已成为了吸引外资最多的国家,但是中国并未成为所有外资的必选之地,在吸引外资方面,中国还面临着其他发展中国家的激烈竞争。不过短期内,中国在吸引外资方面还能继续保持优势地位。从国际竞争的角度看,为了保持和提高我国对FDI的竞争力,我国目前取消外资优惠政策的时机还不成熟。     

A Stakeholder’s Perspective on Human Resource Management

In order to understand the system wherein human resource management practices are determined by the interactions of a complex system of actors, it is necessary to have a conceptual framework of analysis. In this respect, the works of scholars (Mitroff, 1983, Stakeholders of the Organizational Mind, Jessey-Bass; Freeman, 1984, Strategic Management: A Stakeholder Approach, Pitman) concerning stakeholder theory opened new perspectives in management theory. An organisation is understood as being part of a politico-economic system of stakeholders who interact and influence management practices. Each stakeholder tries to optimise and protect his interests (Frooman, 1999, Academy of Management Review 24, 191–205; Savage et al., 1991, Academy of Management Executive 5(2), 61–75). The framework of stakeholder analysis enables escape from a purely instrumental approach to HRM, and avoids reducing our understanding of conflicts within companies to mere antagonism between employees and their employers. It enables us to point out the existence of other stakeholders in the relationship. Notably, it allows for the incorporation into management theory of actors from the sphere of politics (president of the republic, government, national elected representatives – deputies and senators – and locally elected representatives – mayors and regional councillors, etc.) as well as their dependent administrations. All these actors are considered to be stakeholders who define the legal framework of firm management and guarantee the application of these laws.     

Small business survival and inheritance: evidence from Germany

This paper investigates whether small businesses face financial constraints that affect their survival. A model of moral hazard is developed in which financial constraints arise endogenously. The model predicts that higher private assets relax financial constraints and have a positive effect on the firm’s probability of survival. The empirical analysis confirms that the entrepreneur has a higher propensity to stay in business when she inherits capital. This effect is particularly strong for entrepreneurs who switch from self-employment into wage employment.

Alasdair Macintyre’s Aristotelian Business Ethics: A Critique

This paper begins by summarizing and distilling MacIntyre’s sweeping critique of modern business. It identifies the crux of MacIntyre’s critique as centering on the fundamental Aristotelian concepts of internal goods and practices. MacIntyre essentially follows Aristotle in arguing that by privileging external goods over internal goods, business activity – and certainly modern capitalistic business activity – corrupts practices. Thus, from the perspective of virtue ethics, business is morally indefensible. The paper continues with an evaluation of MacIntyre’s arguments. The conclusion is drawn that MacIntyre’s critique, although partially valid, does not vitiate modern business as he claims. In short, modern business need not of necessity be antithetical to individuals’ pursuit of internal goods within practices.     

Are We Sending Mixed Messages? How Philosophical Naturalism Erodes Ethical Instruction

To develop critical thinking skills, higher order ethical reasoning, a better grasp of the implications of ethical decisions, and a basis for ethical knowledge, it is necessary to explore the philosophical premises foundational to one’s ethical persuasion. No philosophical premises are more important than those pertaining to the nature of human personhood and business’ responsibility to respect the inherent value of human beings. Philosophical naturalism assigns the essence of human personhood strictly to causal interactions of physical matter. Substance dualism, on the other hand, posits both a physical aspect and an immaterial substance to personhood, interacting within the totality of each being. This paper argues for the logical superiority of substance dualism in achieving the overriding objective of discerning ethical knowledge. Substance dualism offers a better explanation – and one that more closely follows the way most people commonly experience themselves and others–than naturalism for free agency and accountability, meaningful moral standards, confidence in knowing what ethical decisions to make, and the moral drive residing in conscience.

大垂直口径天线俯仰波束赋形设计

给出了一种大垂直口径天线俯仰波束的优化设计过程。大垂直口径天线由10个辐射阵元 构成,可以看成为一个阵列。为使天线的辐射波束达到给定的波束要求,提出了一种改进 的遗传算法及其目标函数模型,对各辐射阵元的馈电幅度和相位同时进行优化。计算结果显 示,天线能够产生满足设计要求的俯仰波束。通过全波电磁仿真软件HFSS进行了验证,仿真 结果与计算结果吻合,证明了所提方法的有效性和实用性。     

基于误差校正的多因素BP国际碳市场价格预测

碳价预测是碳金融市场参与者进行风险管理的关键要素,已有基于多因素的碳价非线性预测模型没有对碳价影响因素进行降维,造成预测模型复杂;现有研究在对碳价初始预测误差进行预测时,没有考虑不同频率数据适用的预测方法,难以较好地刻画不同频率数据的波动特征.以CER现货价格为研究样本,构建了基于误差校正的多因素BP国际碳市场价格组合预测模型:利用ALASSO方法筛选碳价主要影响因素以达到降维目的,运用BP模型构建基于多因素的碳价初始预测模型;按照分解-重构-集成的思想进行误差校正,即运用EEMD分解初始预测误差,利用游程判定法重构分解项,并分别选用Elman对高频进行预测,运用SVM预测中频和低频,运用ARIMA方法预测余项,将各分项预测值叠加为误差预测值,进而得到校正后的碳价预测值,并与其他模型进行对比.     

房价与地价互动关系的区域性差异研究

我国地域幅员辽阔,房价与地价的关系错综复杂.选取2003年～2015年35个大中城市居住用地地面均价作为地价水平的衡量指标,基于聚类分析将35个城市分为三个区域,通过构建面板回归分析和格兰杰因果检验来分析房价与地价互动关系的区域性差异.结果表明,地价对房价在各地区均有正向影响,但影响程度存在差异.一类地区影响程度最大,三类地区次之,二类地区最小.此外,一类地区房价对地价具有持续性影响.     

坚持科学发展观 大力发展循环经济

无论从维持资源的可持续供应,还是保持良好的生态和环境,发展循环经济都具有重要的现实和战略意义。推动循环经济发展要加强相关理论和实践模式研究,提高各级政府和相关决策部门对其重要性的认识,借鉴国际、国内先进经验,采取综合措施。一是加快制订促进循环经济发展的政策、法律法规;二是加强政府引导和市场推进作用;三是在经济结构战略性调整中大力推进循环经济;四是建立推动循环经济发展的消费体系;五是探索循环经济参与国民经济核算的制度体系;六是开发循环经济的技术支撑体系。
