内向FDI对中国出口扩张影响的实证分析

实证分析1983-2004年期间内向外商直接投资(FDI)与同期中国出口扩张之间的关系,可见FDI提升了内外资企业的出口,尤其是在劳动密集型行业;外资对内资企业带来显著的"市场接近溢出效应",即外资存在促进内资企业的出口.其中来自港澳和日本的投资促进中国出口,而欧美的投资对中国出口影响并不显著.本文的结果进一步佐证了中国政府人民币汇率管理着眼于出口最大化政策的正确性,具有重要的政策含义.     

韦伯命题的再诠释:寻找资本主义发展的精神动力--一个"非帕森斯化"的注解

在传统的帕森斯体系框架中,韦伯命题论证的是新教伦理同资本主义起源之间关系。面对资本主义社会制度已经发生变革的时候,韦伯从研究禁欲新教和现代经济生活的联系着手,试图找到能够继续促进资本主义继续发展的动力,即韦伯反复强调的资本主义的合理伦理和“因果链”的问题。     

太平洋战争前期的美国对华政策——从"珍珠港事件"到开罗会议前

太平洋战争爆发后,面对共同的敌人,美国迅速同中国建立了同盟关系,并加强了对中国的援助与支持。战争初期严峻的军事形势和美国“先欧后亚”的军事战略,决定了在战争前期“打击日本”这个军事目标是美国决策者对华政策的重心。这一时期美国对华军事、经济、政治与外交上的政策与实践都体现了这一点。从某种意义上讲,太平洋战争前期的美国对华政策是成功的,取得了积极效果。     

Ethene/norbornene copolymerization by [Me2Si(3-tertBuCp)(NtertBu)]TiCl2/MAO-catalyst

Ethene/norbornene copolymerization by the catalyst system [Me₂Si(3-^tertBuCp)(N^tertBu)]TiCl₂/MAO was investigated in detail at 30 °C, 60 °C, and 90 °C. A mass flow controller was used in this work to obtain kinetic data and investigate temperature's effects on activity, norbornene incorporation, copolymerization parameter, microstructure, glass transition temperature, and molar masses were described. High copolymerization valuesr _ξ and high alternation are determined. The number of isotactic alternating sequences is much higher than that of the syndiotactic alternating sequences.     

专业镇、产业结构与新型城镇化建设关系研究

产业集聚与新型城镇化的联动发展是提高中国城镇化质量、促进经济社会发展的重要途径,产业结构转型升级与城镇化建设之间存在密切关系.基于广东省东莞和中山两市共56个专业镇2006-2013年的面板数据,运用固定效应模型实证检验专业镇产业结构对城镇化水平的影响.研究结果表明,专业镇产业结构的转型升级会推动城镇化建设进程,并且专业镇的生存期越长,其产业结构优化调整对城镇化水平提高效果越大.     

Average vs. distributional effects: Evidence from an experiment in Rwanda

Programs and policies in education overwhelmingly focus on improving the average academic achievement for students. However, educational interventions focused on literacy improvement can impact readers at different levels of the reading score distribution differently, and the distributional differences may be more pronounced by sex. In this paper, I explore data from a field experiment in a district in Rwanda that was intended to make classroom reading pedagogy more effective and engage students, families, and communities in reading activities outside of school to improve students’ reading outcomes.I study the distributional effects of the intervention on students on two higher-order reading outcomes – Kinyarwanda fluency and Kinyarwanda text comprehension, measured for students who met a basic literacy threshold. I find that a) the set of interventions had a positive and significant, albeit modest effect on students at or above the 25th percentile of the reading distributions b) the program had positive and significant effects on reading outcomes for girls only, and these effects differed along the reading achievement distribution. This work underscores the importance of tailoring programs and policies to the needs of different types of learners.
