众创空间平台定位及其发展策略演进逻辑研究

在“双创”支撑中国经济转型发展背景下,众创空间成为国家和地方政府政策的重要着力点。对于众创空间的内涵,实践界尚未形成共识,众创空间的理论定位及其发展逻辑成为紧迫的研究议题。通过对孵化器和平台研究的文献梳理,采用案例研究方法明晰了众创空间双边创新型平台的定位,揭示了众创空间发展策略“基础架构-网络效应-生态系统”3个阶段的演进逻辑及各阶段关键行动选择。该研究为众创空间实践提供了一个可参考的行动框架,并在阐释众创空间本质内涵的基础上,从政策层面指出了开展众创空间评价所应遵循的要义。

个人、机构投资者情绪与证券分析师的乐观偏差——来自中国A股市场的证据

证券分析师的盈利预测存在着显著的乐观偏差,且这种乐观偏差会因投资者情绪的变化而忽高忽低。基于开户数量构建个人、机构投资者情绪指标,实证研究投资者情绪对证券分析师乐观偏差的影响。研究发现,个人、机构投资者情绪越乐观,证券分析师的乐观偏差越大;机构投资者情绪的波动比个人投资者更为剧烈,且对证券分析师的影响也大于个人投资者;在考虑了公司的截面特征后,结论依然稳健。研究有助于进一步理解新兴市场中证券分析师的盈利预测行为,并为投资者使用证券分析师的研究报告提供决策参考。     

全球大宗商品定价机制与国际经贸格局演变动态关系的研究评述

大宗商品及其价格波动的研究始终是国际经济学领域中备受关注的话题。近年来,全球大宗商品价格经历了错综复杂的变化,各方围绕大宗商品尤其是能源的定价权展开了激烈的斗争,并进一步引发了全球经济贸易格局的深刻调整。"中国因素"如何影响国际大宗商品价格机制以及如何提高中国的国际大宗商品定价权已成为具有深远意义且艰巨的课题。本文通过对国内外相关文献的综述,介绍了大宗商品价格波动的成因及对经济的影响、大宗商品定价机制的变迁及定价话语权的提高方式、大宗商品与经济安全的关系等,指出了现有研究存在的不足之处,揭示了全球大宗商品定价机制与国际经贸格局动态演变关系研究中可进一步探讨和突破的空间。     

Social Capital or Ethnic Enclave Location? A Multilevel Explanation of Immigrant Business Growth

The rapid increase in migration into host countries and the growth of immigrant‐owned business enterprises has revitalized research on ethnic business. Does micro (individual)‐level social capital, or meso (group)‐level location within the ethnic enclave lead to immigrant business growth? Or do you need both? We analyze quantitative data collected from 110 Chinese restaurants in Australia, a major host country. At the micro level we find that coethnic (same ethnic group) networks are critical to the growth of an immigrant entrepreneur's business, particularly in the early years. But non‐coethnic (different ethnic group) social capital only has a positive impact on business growth for immigrant businesses outside the ethnic enclave. Our findings are relevant, not only to host‐country policymakers, but also for future immigrant business owners and ethnic community leaders trying to better understand how to promote healthy communities and sustainable economic growth. © 2015 Wiley Periodicals, Inc.     

Who will make an indulgent food choice after having fulfilled their healthy eating goal?

This research considers how subjective nutrition knowledge and calorie consciousness moderate the effects of eating goals on indulgent vs. healthy consumers and their on subsequent choices. A two between‐subjects design (an eating goal invoked by a main course: healthy vs. indulgent) was conducted, where the choice of salad dressing (healthy or indulgent) was a dependent variable. Two individual traits (subjective nutrition knowledge and calorie consciousness) were considered as moderators between eating goals and food choices. The results indicated that individuals with high levels of subjective knowledge about nutrition or with a high level of consciousness about calories were more likely to choose a healthy option when their indulgent goal had been invoked. However, they were more likely to make indulgent choices when their healthy goal had been fulfilled by the main course. In contrast, for those with low levels of subjective nutrition knowledge or with a low level of consciousness about calories, food choices were not influenced by the eating goal which had been invoked. The findings could help practitioners in the food industry to develop different food combinations with which to satisfy their customers through understanding personality traits.     

我国股指期货价格发现功能的再探讨——来自三个上市品种的经验证据

本文首次采用沪深300、上证50和中证500三个品种股指期货与现货的5分钟高频数据,在静态和动态递归协整分析框架下,通过长期弱外生检验、广义方差分解、永久短暂模型以及信息份额模型,从统计和经济显著性两个方面,对我国股指期货与现货的价格发现功能进行全面考察,把握了其时变特征.实证结果表明,三个品种的股指期货与现货具有比较稳定的长期均衡关系.对于沪深300和中证500股指期货与现货,期货价格为弱外生变量的频率都在90％以上,期货引导现货;在剩余不到10％的递归子样本下,期现价格相互引导;而且在所有的递归样本中,期货的价格发现贡献度都高于现货.对于上证50股指期货与现货,期货引导现货的频率达到70％以上,两者相互引导的频率在10％左右,此时,期货的价格发现贡献度高于现货;但在本次股灾期间,同时也出现了现货引导期货、现货价格发现贡献度反超期货的特殊情形.总体而言,我国的股指期货市场正在逐步走向成熟,具备了良好的价格发现功能.     

地理位置、环境信息披露与股价同步性--基于政策变动的研究视角

在政策变动的背景下,公共压力与空间距离都是影响股价同步性的重要因素,前者减弱股价同步性,后者增加股价同步性,但两者共同通过环境信息披露进行作用对股价同步性会产生怎样的影响是目前必须解决的问题。本文选取2004－2006年和2009－2011年我国上市制造业企业为样本,以政策变动为视角,研究了环境信息披露差异对股价同步性的影响机制。结果发现,在《办法》颁布前,远距离企业的环境信息披露与股价同步性负相关,《办法》颁布后则正相关。而对于近距离企业,在《办法》颁布前后均不显著。因此,在公共压力增大的情况下,环境信息披露对股价同步性影响的过程中,地理位置起到了决定性的调节作用,应引起监管层的足够重视。     

CEO Power,CEO Age and the Policy Instrument Property of State-Owned-Enterprises

In this paper, we examine the relationship between CEO power, CEO age and the efficiency of policy implementation in listed corporations controlled by each province’s State-owned Assets Supervision and Administration Commission (SASAC) in China. We find that CEOs with more power implement policy are more efficiently. We also find that younger powerful CEOs will act more effectively than their older competitors. The reason for the difference is that younger powerful CEOs in state-owned companies are incentivized to implement their policy tasks to gain promotions or political capital. Our results are important to future SOE reform and to understanding the characteristics of SOEs as policy instruments.     

政策不确定性的宏观经济后果

本文采取贝克的政策不确定性指数,运用FAVAR方法分析政策不确定性冲击对中国宏观经济的影响。经验结果发现,政策不确定性冲击对GDP、投资、消费、出口和价格变动会带来负向影响,导致实际有效汇率贬值,促使股票价格和房地产价格下跌。同时发现,政策不确定性作用于宏观经济的主要机制为预期渠道。该结论表明,政府应当尽量保持宏观经济政策的稳定性和持续性,并加强引导公众合理预期。
