宏观经济因素对银行体系脆弱性影响的实证分析

本文运用实证分析方法研究宏观经济因素对我国银行体系脆弱性的影响.Logit回归分析结果表明,经济发展水平对银行体系脆弱性具有显著负向影响,但影响程度较小;货币供给因素、投资因素及资本市场规模对银行体系脆弱性具有正向影响,其影响程度较大.脉冲响应分析结果表明,经济发展水平、货币供给对银行体系脆弱性具有负向冲击效应,投资因素对银行体系脆弱性具有正向冲击效应.研究结果可为建立健全银行体系与宏观经济的协调发展机制提供参考依据.     

Underwriter reputation,earnings management and the long‐run performance of initial public offerings

This study contributes to the extant literature on the nature of earnings management surrounding initial public offerings (IPOs) by investigating the role of underwriter reputation. We argue that prestigious underwriters will protect their reputation by carefully monitoring and certifying financial information on IPO firms, thereby limiting any potential earnings manipulation. As a result, those IPO firms that are associated with more prestigious underwriters are likely to exhibit substantially less‐aggressive earnings management. Conversely, we find the existence of a negative relationship between earnings management and the post‐offer performance of an IPO firm’s stocks only for those firms associated with less‐prestigious underwriters.     

循环经济背景下的绿色物流发展策略研究

随着我国经济的迅速增长,资源与环境制约传统经济增长的态势之下,循环经济成为必然选择。然而,"第三利润源泉"——物流,在广泛开展的同时产生诸多负面影响,显然与循环经济相悖。资源的短缺,政府、社会对环境问题的广泛关注与管制,使绿色物流成为必然选择。     

网络口碑营销研究进展述评

本文对CNKI和ISI数据库中167篇网络口碑营销的文献进行了研究主题和研究方法的分析。结果发现,国内在网络口碑营销的研究内容和理论深度上与国外相比存在明显的滞后。国外研究主题侧重于网络口碑与消费者行为关系、网络口碑效应以及网络口碑可信度等方面。国外以调查实证和实验研究方法为主,国内则以描述性为主。未来可以通过调查或实验方法就中性网络口碑的作用以及网络口碑作用机理等开展研究。     

中国工业部门能源使用效率及其影响因素研究

本文对我国工业部门的全要素能源使用效率进行了测算,结果表明,考察期内全部样本行业的能效均值基本维持在50%至60%水平之间,能效水平总体不高.能源使用效率存在着较为显著的行业间差异,采掘业能效水平均值要高于轻工业和重工业.总体能效水平以2002年为拐点,出现了先上升后下降的变化轨迹.采掘业能效水平在考察期内有所波动,但基本能够维持在相对较高水平,重工业呈缓慢上升态势,而轻工业则在2002年以后出现了大幅下降.通过计算标准差,我们也未发现能效出现行业趋同.企业平均规模的扩大、市场竞争强度的降低、外资规模的增加对行业能效提高具有积极影响.     

我国农村劳动力资源转移模式研究

对于农业和农村问题,我们已经形成这样的看法:即没有农村的稳定就没有全国的稳定,没有农民的小康就没有全国的小康,而农民的小康只有通过辛勤劳动才能获得。可见,如何解决农村劳动力的就业问题,关系到我国社会经济发展战略目标的实现。因此,如何     

Do environmental regulations hamper small enterprises' market entry? Evidence from China

Due to the serious increase of environmental pollution in China, environmental regulations have become significantly stringent. Such regulations are playing an increasingly important role in the development of small enterprises (SEs) in China, especially in SEs' market entry. However, existing studies pay little attention to this issue. This paper investigates for the first time the effect of environmental regulations on SEs' market entry and the mechanism of environmental regulation effects in China. We consider two sets of panel data for the periods 2003–2010 and 2012–2015 in China. We also use the fixed effect model and the instrumental variable method to explore the role of environmental regulations in SEs' market entry. The results show that, overall, environmental regulations play a significantly positive and robust role in SEs' market entry. However, the mechanisms associated with the effect of environmental regulations on different innovative types of SEs differ. Environmental regulations promote the market entry of SEs with product innovation, but this impact is not significant for SEs with research and development (R&D) activities and R&D institutions. Our findings indicate that China's SEs prefer product innovation, which is a lower level innovative type, over R&D innovation, as a means to avoid the negative impact of stringent environmental regulations.

基于电子舌传感技术评价不同市售啤酒滋味品质

应用电子舌传感技术和多元统计学方法相结合的手段,本研究对市售6个啤酒品牌下15个样品的滋味品质特征进行综合评价分析。结果表明,评价啤酒品质的8种滋味指标可以划分为三大类,其中第一主成分由酸味、鲜味和鲜味的回味组成;第二主成分由苦味和苦味的回味组成;第三主成分由咸味、涩味和涩味的回味构成。因子分析发现综合得分排名前三的啤酒样品分别为C_1、F_1和E_1。与此同时,通过聚类分析可以将15个不同品牌与类型的啤酒样品按照滋味品质的差异情况分为5类,与现有啤酒市场行情相符。研究说明电子舌传感技术在啤酒品牌区分、品质口感判定和市场分析中具有巨大的应用潜力。     

Institutional trading in IPOs and post-IPOs: Value-based vs speculative

Using a unique dataset from Shanghai Stock Exchange, we study institutional trading behaviors in IPOs and post-IPOs. From the perspective of value-based or speculation, we find that, (1) institutional investors are flippers on the first day of IPOs, (2) trading by institutional investors and the active institutional investors (mutual funds or brokerage) is value-based, and (3) the net buys of institutional investors can predict the long term performance of IPO-firms and shows a negative relation with a bubble in future. Since individual investors are the opponent of institutional investors, our results mean that individuals are speculators in the market. Our study suggest that institutional investors are the sophisticated ones in the market and they can process information more efficiently, whose value-based trading can enhance market price discovery and is good for market stabilization.
