企业规模、经济增长与收入不平等——基于我国工业部门的动态计量分析

以中国工业部门为例,对比我国工业小企业发展、当前的收入分配状况及经济增长,对这些时问序列运用向量自回归方法,并通过脉冲响应函数及方差分解分析,得出结论:在对经济增长的贡献上,小企业与大中型企业相比并无效率优势,但小企业的发展更有助于缓解收入差距的扩大.     

农民工职业成长及其个体影响因素分析——基于浙江259份问卷数据

基于浙江259份农民工的问卷调查数据,回归分析了人力资本、社会资本和心理资本等个体因素对农民工职业成长的影响。结果表明:人力资本变量中培训次数和换工次数均对农民工被提拔次数正向影响显著;总务工年限对工资提升、岗位调整次数、被提拔次数正向影响显著。社会资本作用有限,仅亲朋好友间的联系频繁程度与被提拔次数以及聚会花费与岗位调整次数呈弱相关。韧性等心理资本因素对工资提升和岗位调整次数正向影响显著。

开放经济体中知识产权与经济增长关系的实证分析

近年来,新兴国家研发成果已成为全球创新格局中不可忽视的部分;各国知识产权合作继续加强,并呈现出向发达国家标准收敛的明显趋势;同时,对知识产权在不同经济条件下对一国经济增长作用的争议愈加突出.为厘清包括中国在内的技术跟随国家知识产权与经济增长的关系,文章针对开放经济环境中技术领先国家和技术跟随国家的创新能力、知识产权保护力度和经济增长状态的关系进行了实证分析.在内生经济增长框架中,创新地采用专利族信息,通过对37个样本国家1990-2013年的面板数据分析,选用固定效应模型对前述变量间长期均衡关系进行了探讨;指出技术跟随国家的知识产权保护对技术领先国家有明确的促进作用,而对本国创新和经济增长的效应则取决于本国具体情况.     

多维城乡差距与中国经济包容性增长

采用 Ｈｉｃｋｓ Ｍｏｏｒｓｔｅｅｎ指数对中国省域以多维城乡差距为非期望产出的包容性全要素生产率进 行测度和比较分析,结果表明：考虑多维城乡差距的包容性 ＴＦＰ指数低于传统 ＴＦＰ指数,技术进步的快 速下降是导致 ＴＦＰ指数下降的重要原因;城乡差距较小的东部地区包容性 ＴＦＰ指数高于中西部地区, 包容性经济增长存在区域差异;滞后一期的城乡产业发展差距对包容性经济增长具有显著的抑制作用。 全国以及中西部的经济发展水平与包容性经济增长存在“倒 Ｕ型”关系,城乡差距较小的东部地区,地 区经济发展与包容性经济增长正相关。城镇化率有助于推动全国以及东、中部地区包容性经济增长,但 与西部地区包容性经济增长负相关。产业结构对包容性经济增长具有抑制作用。要推动经济包容性增 长,必须缩小多维城乡差距,注重经济高质量发展,推动产业合理布局,并根据各地区不同的经济发展以 及城乡发展阶段采取不同的发展战略。     

金融集聚、生产率增长与城乡收入差距的实证分析——基于动态空间面板模型

本文利用中国2003-2013年285个地级及以上城市的统计数据,采用动态空间面板模型实证分析了金融集聚对城市总体生产率增长及其内部城乡收入差距的影响,研究结论表明：金融集聚是促进城市总体生产率增长的重要推动力,同时也是导致城市内部城乡收入差距扩大的关键因素,这主要是因为金融集聚显著推动了城市居民人均收入水平的提高,而对农村居民人均收入水平的提升作用不显著。本文的政策含义在于,在城市金融集聚的扩散阶段还没有到来之前,政府旨在缓解城乡收入差距的金融政策可能会抑制城市总体生产率增长。     

Service diversification and growth of professional service firms

This study investigates the impact of service diversification on the rate and mode of firm growth in professional service firms (PSFs). Drawing on the extant PSF literature, we identify differing views regarding the growth impact of service diversification. Specifically, some scholars suggest that the external client benefits associated with service diversification should allow PSFs to expand revenues at a rapid pace and pursue less merger and acquisition activity, whereas others imply that increased diversification can cause internal challenges with respect to learning costs, coordination and innovation that can limit the rate of revenue growth and encourage more mergers and acquisitions. We test these competing views using longitudinal data on 137 accounting firms and cross-sectional data on 125 law firms and find that service diversification is negatively associated with the rate of firm revenue growth and positively associated with the use of mergers and acquisitions.     

绿色增长下的导向性技术创新选择研究

针对如何正确引导 GHG 排放的气候反馈经济损失下导向性技术创新,以实现长期的绿色增长这一问题,基于 DICE 模型,重构导向性技术创新不同的动力要素及其与气候变化之间的内生关系,建立了可体现绿色增长“均衡性”、“包容性”和“可持续性”的非线性最优控制模型。数值仿真结果显示: 气候反馈经济损失不容小觑; 偏于生产的绿色技术创新导向下社会生产力强劲但存在气候环境恶化风险,偏于减排的绿色技术创新导向下气候反馈经济损失小但存在增长动力匮乏风险,二者虽均可实现长期的绿色增长,但中性的绿色技术创新导向会更稳妥; 偏于生产的绿色技术创新导向下人均消费变化率在短期内会显著提升。     

The Transnational Tilt of the Treadmill and the Role of Trade Openness on Carbon Emissions: A Comparative International Study, 1965–2010

There are various schools of thought regarding the relationship between the environment and economy. Ecological modernization argues that the harmful effects of economic growth and development on the environment decline through time, whereas the treadmill of production and ecologically unequal exchange postulate different perspectives. This study relies on World Bank and World Resources Institute data for the period of 1965–2010. Time‐series cross‐sectional Prais‐Winsten (PW) regression models with panel‐corrected standard errors (PCSE) are employed to examine whether economic growth and trade openness intensified or decoupled in relation to three measures of carbon dioxide (CO₂₎ emissions during this period. The findings of this study indicate that there has been a “tilt” in the treadmill of production—that is, the most environmentally degrading production processes have moved to less developed countries. Furthermore, integration into the world economy has been associated with an intensification in CO₂ emissions for less developed countries. Surprisingly, however, this phenomenon does not seem to be driven by exports sent to high‐income nations, suggesting that there are mechanisms embodied within the global organization of production that require further exploration.     

Exploring patterns of personal growth initiative and posttraumatic stress: A latent profile analysis

Objective: This study examined the inconsistent relationship found between personal growth initiative (PGI) and posttraumatic stress symptoms (PTSS) by exploring potential subgroups. In addition, after identifying the subgroups, potential predictors of these subgroups were examined. Participants: Participants were 534 undergraduate students who experienced a potentially traumatic event (PTE). Data collection occurred from March 2013 to December 2014. Methods: Because this was a preliminary study, archival data was used. Participants consisted of students who experienced a PTE within the past three years. Results: Latent profile analysis indicated a five-class model as the best-fitting model. Direct exposure and intentionality of the event were significant predictors of class membership; length of time since event and gender did not predict class membership. Conclusions: The current study provides a potential explanation of the inconsistent results between PGI and PTSS and also highlights the importance of acknowledging subgroups when utilizing PGI after a PTE.
