中国服务业跨国公司成长特征分析——基于2007年末中国非金融类对外直接投资前四十家公司的分析

中国服务业跨国公司已成为中国对外直接投资的主力军。中国服务业跨国公司的成长是必然的,其存在的共性决定了中国服务业跨国公司成长的特征。中国服务业跨国公司的成长得益于其国际竞争优势的综合性,但发展的阶段性及优势的脆弱性特征成为中国服务业跨国公司必须面对的问题。本文在特征分析基础上探讨了相关的战略建议。     

Fiscal Consolidations and Economic Growth

The aim of this paper is to deepen the understanding of the macroeconomic consequences of fiscal consolidations. In particular, there is evidence in the literature of fiscal consolidation episodes producing (non‐Keynesian) expansionary effects in the short run. We replicate this result for a panel of OECD countries under exogeneity of the fiscal consolidation. However, we provide some evidence that output growth might affect the fiscal tightening process so that fiscal consolidations are not exogenous to economic growth. Once we allow for feedback effects from economic growth to fiscal adjustments, we find that expansionary effects disappear and recover the typical Keynesian effect of fiscal adjustments. This finding points to the need to take these short‐term negative implications into account in the design of fiscal consolidations.

制度经济学视角的国有商业银行弱势群体分析

国家所有的独特的产权制度安排以及由此而形成的对国有金融机构的行政干预,导致了国有商业银行在竞争中的强垄断地位,阻碍了体制外因素对国有商业银行竞争压力的释放,进而导致了国有商业银行市场行为的低效,成为渐进式改革中独特的弱势群体.因而,从体制上破除"父爱主义"的产权制度和国家主导下的超强垄断地位,引入公平的竞争机制成为提高国有商业银行竞争力、改变目前弱势地位的关键和前提.     

Comparative Statics of Money-goods Specifications of the Utility Function

The introduction of real-cash balances into the neoclassical model of the consumer wrecks havoc, in general, on the empirically observable refutable comparative statics properties of the model. We provide the most general solution of this problem to date by deriving a symmetric and negative semidefinite generalized Slutsky matrix that is empirically observable and which contains all other such comparative statics results as a special case. In addition, we clarify and correct two aspects of Samuelson and Sato's (1984) treatment of this problem. Received March 9, 2001; revised version received September 3, 2001     

Demand Aggregation and the Weak Axiom of Stochastic Revealed Preference

We address the problem of aggregating demand across a group of consumers, who are identical in terms of wealth and face identical price vectors, but vary in their chosen consumption bundles. We show that, when a stochastic demand function is constructed to aggregate a number of deterministic demand functions, satisfaction of the weak axiom of stochastic revealed preference by this stochastic demand function is weaker than the restriction that every underlying deterministic demand function satisfy Samuelson's weak axiom of revealed preference.

浅析大学生犯罪行为——从马加爵案和李征案说开去

马加爵和李征既属于贫困大学生群体，也是青少年弱势群体中的一员。这两起案件，相隔两年，其发生有偶然性，更有其必然性。研究这两起案件，对于完善高校教育体制、促进大学生健康成长和完善青少年犯罪的体系、结构等，具有重大的意义。     

弱势群体的经济成因及其社会保护

弱势群体源于社会变革和公民个体的生活变迁。弱势群体与一般社会公众的生活距离和区别,不仅在生活内容和生活水平上,也包括心理方面的特殊性。弱势群体的产生和存在对社会的稳定、发展有不可忽视的消极影响。着力转化、提升弱势群体是社会控制和政府管理的重要课题。     

论我国现阶段的“强资本”与“弱劳动”

劳动关系的和谐是构建社会主义和谐社会的微观基础和必然要求。然而,中国现阶段却存在“强资本”与“弱劳动”导致的劳动关系扭曲。“资强劳弱”的劳资关系,给经济社会发展带来了巨大的危害。为构建和谐的社会主义劳资关系,必须弱化劳动力过剩的程度,加强劳动者的组织建设,强化劳动者的权益保护,构建企业利益共享机制。     

弱信号下“北斗”接收机NH码的快速捕获

在全球卫星导航系统(GNSS)中,延长相关累积时间可以有效提高弱信号捕获灵敏度,但是“北斗”中圆地球轨道/倾斜地球同步轨道（MEO/IGSO）卫星信号的捕获性能很大程度上受到二次编码(NH)码的影响：调制NH码的信号在每一个码元周期(1 ms)内都有可能发生跳变,对相关累积时间造成一定影响,从而会导致系统捕获灵敏度的下降。为此,提出了一种针对NH码的码元遍历搜索算法,通过遍历累积时间内NH码的所有组合,消除NH码码元引起的误差。实验结果显示,所提算法可以在一定程度上提高卫星信号的捕获成功率,尤其可以至少提高2 dB弱信号的捕获灵敏度。同时,算法可以为信号跟踪提供更加准确的载波频率。
