论民族区域自治制度在我国国家政治制度中地位的变化

中国共产党自成立之初起,就把解决民族问题、实现民族平等作为中国新民主主义革命的一项重要内容,但正式提出以民族区域自治作为解决我国民族问题的一项政策,并且进一步将民族区域自治作为国家的一项基本政治制度则经历了长期的探索过程,民族区域自治制度从最初确定为国家的一项政治制度,到定位于国家的重要政治制度,再到定位于国家的一项基本政治制度,总共走过了50多年的历程。本文分阶段详细地分析了这项制度在国家政治生活中地位变化的过程及背景。     

地区与国家GDP核算总量数据衔接方法比较研究

 本文以国家数据为准,通过采用2005-2009年的数据为样本,从理论与实证上比较分析了地区与国家GDP数据衔接的三种方法即Geary和Stark的产出估算方法、线性调整法与辅助回归法,比较结果显示：（1）从理论上分析,三种方法都有其合理性,只是辅助回归法较另两种方法更具可取性。（2）从衔接效果上看,辅助回归法优于Geary和Stark的产出估算方法,Geary和Stark的产出估算方法又优于线性调整法。不过不同的方法皆有相应的适用场合与特点以及不同的衔接效果,因而只能说三种方法中有趋优的方法,但不能明确断定何种方法可以具体应用于实际数据衔接中并能达到良好的调整效果。     

An Approach to Determine Sample Size and to Allocate Sample Size for a Specific Region in a Multiregional Trial for Survival (Time-to-Event) Data under Accelerated Failure Time Model

For the time-to-event outcome, current methods for sample determination are based on the proportional hazard model. However, if the proportionality assumption fails to capture the relationship between the hazard time and covariates, the proportional hazard model is not suitable to analyze survival data. The accelerated failure time (AFT) model is an alternative method to deal with survival data. In this paper, we address the issue that the relationship between the hazard time and the treatment effect is satisfied with the AFT model to design a multiregional trial. The log-rank test is employed to deal with the heterogeneous effect size among regions. The test statistic for the overall treatment effect is used to determine the total sample size for a multiregional trial, and the proposed criteria are used to rationalize partition sample size to each region.     

论亚太地区预防性外交的发展

冷战结束以后,预防性外交成为备受国际社会关注的处理安全问题的新方式。随着1994年东盟地区论坛的成立,亚太地区各国展开了预防性外交的大讨论。由于各国间存在着巨大的差异性,围绕预防性外交的基本概念产生了很大的争论。但是通过东盟地区论坛等多边合作机制的发展,在追求共识、求同存异的基础上,各方通过交流寻找普遍接受的共同原则,正在形成有亚太地区特色的预防性外交理论。     

中国人口老龄化区域溢出与分布差异的空间计量经济学研究

将空间因素纳入我国人口老龄化问题的研究框架,对各地区人口老龄化的空间分布特征进行概括和探索性空间数据分析,利用空间计量经济学理论方法和空间误差模型,对各要素影响作用的方向和大小进行实证研究,最后得出综合结论和政策建议。除老龄化惯性、人口增长以外,首次对人口老龄化区域溢出机制进行了重点阐述。我国人口老龄化区域溢出作用不仅客观存在,而且影响显著,这一发现从空间维度拓宽了研究视野,为我国人口老龄化问题理论研究和政策制定提供了有益的借鉴。     

Does innovation lead to global orientation? Empirical evidence from a sample of Italian firms

This paper analyses the relationship between innovation at firm and industry level, and the global vs regional strategy of multinational enterprises (MNEs). Based on data from a sample of large Italian manufacturing firms, the analysis shows that technological assets affect a firm’s ability to overcome the liability of (regional) foreignness: the extent to which MNEs can exploit their firm-specific technological advantages is greater within their home region, but they also exploit them outside it. Furthermore, the results show that a firm’s foreign (outside the home country) and global sales (outside the home region) are higher, the greater the technology intensity of the industry in which they operate. These findings suggest that, although MNEs tend to operate regionally rather than globally, their strategic orientation is contingent upon firm- and industry-specific factors. Managers need to take the potential for globally exploiting R&D investments into account, even if it may not be equally successful within and outside the home region, and may be constrained by a number of inter-regional barriers.     

The moderating effects of home region orientation on R&D investment and international SME performance: Lessons from Korea

Drawing from the resource-based view, we investigate how firm and country combinations affect international SME performance. Using a sample of 2676 international Korean SMEs, we explore the relationships among SME R&D investment, home region orientation and financial performance. Results show that R&D investment has a horizontally inverted S-shaped relationship with performance reflecting cost leadership, stuck in the middle, and differentiation strategies. We also find that a home region orientation moderates the relationship between R&D investment and performance. Home region orientation positively moderates the relationship when R&D investment reflects cost leadership or differentiation but negatively moderates a stuck in the middle strategy.     

我国区域经济合作的主要动力和发展趋势研究

当前,我国区域经济合作具有四大动力和四大趋势。四大动力分别是政府推动产生的牵引力、市场推动产生的驱动力、资源共享和利益双赢产生的向心力和区域之间的差异性和互补性产生的吸引力。这些动力的综合作用使得我国区域经济合作呈现四大趋势:一是以经济区或经济带为平台,区域合作具有坚实的载体;二是以合作区域的基础设施、创新体系、环境保护、市场体系、社会事业等领域的一体化发展为目标,合作成本不断降低;三是合作双赢或多赢局面日益普遍,合作收益不断增加;四是合作范围日益国际化,使得区域合作的空间资源配置效率不断提升。     

区域经济增长中的区域金融支持策略研究——以陕西省为例

金融市场结构的失衡制约了金融市场整体功能的充分发挥和核心竞争能力的进一步提升。金融市场结构是一个质与量相统一的相对独立系统,一个国家或区域的金融市场结构优化与否则直接反映了其金融市场发展水平的高低。本文通过对陕西省金融业发展的现状进行分析来反映陕西省金融市场结构优化问题。     

基于收入构成的农民收入的地区差距及其演变

为了探索农民收入地区差距的变动趋势,本文选取1995-2009年的省级农民人均纯收入数据,利用基尼系数从收入来源角度探究农村地区差距的构成及变动,找出最主要的因素。研究结果表明,工资性收入是构成地区差距的主要因素,家庭经营收入始终起着差距促减作用。农村地区收入差距的拉大主要归因于结构效应。
