北京都市区人口空间发展的新特征与启示

采用统计分析和探索性空间数据分析方法,在第四、第五、第六次人口普查乡镇街道数据的基础上,着重探讨了北京都市区2000年以来人口空间发展的新特征.研究表明,2000年以来,北京旧城区人口整体实现了正增长,改变了绝对数量不断下降的趋势,增加了人口疏解的难度.远郊区人口增速超过近郊,逐步演化为郊区化的主要承载空间,显示出远郊新城在集聚人口方面的吸引力.全局Moran指数显著为正且逐年减小,揭示人口的郊区化扩展,但2000以来这种趋势有所减弱.局部Moran指数揭示高-高类型集聚区以旧城区为中心逐步向外围扩展,新增的高-高类型区主要位于西北部和北部,减少的区域主要分布于二环以内.低-低类型区分布于都市区的外围,并且向西部的门头沟区和西南部的房山区逐步集中.说明新时期北京都市区人口空间发展存在大范围的集聚和小范围的扩散两种趋势,即人口从都市区外围向近郊及远郊新城集聚,同时由旧城中心部分街道向外围扩散.     

Social Justice and Affirmative Action in Malaysia: The New Economic Policy after 50 Years

Malaysia's New Economic Policy (NEP), promulgated in 1971, established a two-pronged national social justice agenda of poverty reduction, and social restructuring or pro-Bumiputera affirmative action. This distinction of these policy objectives must be appreciated, but various misconceptions, especially regarding affirmative action, have resulted in polarization and stalemate after 50 years of the NEP. Social justice and affirmative action must be conceptualized and evaluated with clarity and rigor, with policy objectives, mechanisms and outcomes aligned. Malaysia needs to systematically formulate a new social justice paradigm, building on the NEP and anchored on the principles of equality and fairness. In the affirmative action sphere, this framework must focus on developing capability and competitiveness, and balance identity, need and merit in the allocation of opportunity.     

Foreign competition and optimal privatization with excess burden of taxation

We examine in a mixed oligopoly setting how foreign competition and the excess burden of taxation will affect privatization policy in the presence of strategic tax/subsidy policies. We show that in the presence of excess burden of taxation with foreign competitors, output subsidy coupled with import tariff and partial privatization is adopted to improve the social welfare. However, if the excess burden of taxation is relatively large, the government may switch to use production tax coupled with tariff policy and partial privatization to improve the social welfare.

基于产品生命周期的物流系统动态规划研究

由于在产品不同生命周期阶段市场竞争具有不同的特征,因此企业采取的市场战略也有较大的差别。应用物流系统的动态评价方法,研究了有效支撑企业产品市场竞争战略的物流系统应该具有的关键性特征,并在此基础上分析了如何组织企业内外部的物流资源,使得物流系统成本最小化的动态规划问题。     

Real exchange rate dynamics in the presence of non-traded goods and transaction costs

This paper studies the role of non-traded goods and transaction costs in accounting for the puzzling behavior of real exchange rates. We show that introducing the transaction costs and non-traded goods in an otherwise standard competitive model dramatically improves its ability to rationalize observed real exchange rate dynamics.     

和谐社会构建与政府干预的路径选择-从英国政府拟实行人体器官捐赠"推定同意"规则谈起

和谐社会的要义在于,政府干预在增加某些居民的福利时,不能以另外一些居民的福利损失为代价。目前在各国盛行的以新古典经济学理性经济人为假设前提的自由主义政府干预理论难以满足这种严格的帕累托改进要求。本文采用行为经济学分析框架,以器官捐赠为例,剖析居民认知偏差导致行为偏误的形成机制,以此重新构建政府干预的微观基础,修正政府干预边界,促成政府干预的技术创新。行为经济学框架下以锁定政策为代表的不对称家长制干预技术,能够有效纠正那些具有认知偏差的居民的行为偏误,却不会对理性居民造成负的外部性影响。这种干预效果的非对称结构与帕累托改进标准存在逻辑上的一致性,可为和谐社会政府干预提供系统的解决方案。     

Multimarket Contact and Rivalry over Knowledge‐based Resources

Research summary: Research shows that multimarket contact (MMC ) reduces rivalry involving downstream activities. Yet, studies showing that MMC can increase the threat of imitation suggest a need to better understand how MMC affects upstream rivalry over knowledge‐based resources. In this study, we argue that MMC increases rivalry over knowledge‐based resources since the deterrent threat of retaliation that typically leads to mutual forbearance in downstream activities will not be sufficient to restrain firms from protecting their knowledge from imitation in upstream activities. In support of these arguments we find that MMC increases the likelihood that a firm initiates patent litigation against a rival. This study suggests the relationship between MMC and rivalry may depend on the competitive domain and the type of resources over which firms are competing . Managerial Summary: How does market overlap or MMC affect rivalry between two competitors? Prior studies have largely found that an increase in market overlap decreases rivalry in less knowledge‐intensive context because of the deterrent threat of retaliation. However, in this paper, we argue that an increase in market overlap may not reduce rivalry in more knowledge‐intensive context because of heterogeneity in capabilities to protect knowledge. We find that a firm is more likely to initiate patent litigation against a rival as market overlap increases. Our findings suggest that the incentive to protect value across multiple product markets may surpass the motivation to cooperate with rivals and that managers should have a more nuanced view of how market overlap with competitors affects rivalry in more knowledge‐intensive contexts .

差序格局、国家圈子和数字经济全球税收治理——基于社会学的视角北大核心CSSCI

考察国际组织与部分国家应对数字经济税收挑战的实践发现,各国应对数字经济税收挑战、磋商新的征税规则,在个体层面表现出以"己"为中心的差序格局,在国家集团层面则呈现出以大国(强国)为中心的国家圈子特征。大国(强国)相互信任、大国(强国)在国家集团或国际组织中处于中心位置、大国(强国)超越国家集团或国际组织的小圈子,对于构建数字经济税收新秩序、形成全球税收治理新体系至关重要。未来构建数字经济全球税收治理新秩序,根本之道在于破除数字经济征税规则重塑中的差序格局现象,跨越国家圈子现象,超越国家利益考量,基于大共识完善包容性制度框架,构建共建共治共享的数字经济全球税收治理共同体。
