境外上市与企业投资效率

截至2021年11月,我国单独境外上市企业占到境外上市企业总数的88.32%,但单独境外上市的研究明显与该数据不匹配,研究数量缺乏。为扩充该方面研究,本文以2012~2020年单独在美国和中国香港上市的中资企业为研究对象,对境外上市与投资效率关系进行检验。实证结果发现,单独境外上市与境内上市企业相比投资效率更低,区分企业上市地点后发现,规模大、信息透明度低、存在代理成本的赴港上市企业比境内上市企业投资效率低,规模小、代理成本高、信息透明度低的赴美上市企业比境内上市企业投资效率低。通过机制分析发现,信息透明度、境外上市和非效率投资三者存在"遮掩效应",境外上市企业未能受到有效的信息约束。     

碳排放约束视角下产业智能化对区域经济差距的影响研究

本文利用2003~2019年中国省级面板数据,从碳排放约束视角出发,实证考察了产业智能化对区域经济差距影响的差异性和产业智能化影响区域经济差距的机制。研究表明,产业智能化对缩小全国、东、中和西部地区省域间经济差距具有显著的正向效应;进一步考虑碳排放约束,发现碳排放约束正向调节了产业智能化对区域经济差距的正向效应,西部地区由于自身产业结构和区位因素,抑制了产业智能化对区域经济差距的正向效应;最后,对产业结构升级的两个子维度在产业智能化和区域经济差距间的中介效应检验,发现产业结构升级的中介效应存在,且主要是通过产业结构高级化实现,产业结构合理化发挥的作用较小。     

Is the January effect still alive in the futures markets?

The January effect concerns the fact that small capitalization stocks have historically outperformed large capitalized stocks in January. We analyze evidence as to whether this anomaly can be exploited in the futures markets as a speculative investment or to add risk-adjusted value to portfolio performance. We find that the January effect is still alive in the futures markets on the Value Line minus S&P 500 spread trade, but that the marginal liquidity of the Value Line stock index futures contract has made it very risky to exploit the effect. Historically from 1982/3 to 2004/5, the trade has been profitable. This anomaly was also exploitable through a Russell 2000 minus S&P 500 spread trade from 1993/4 to 2004/5.

商业周期与区际经济一体化——自然壁垒、经济结构与政策

文章着重从商业周期角度来对我国区际一体化状况进行实证研究,即主要从"市场自然分割"与"政策与经济结构"两方面因素来探索商业周期的区域差异.总体来看,我国所有地区在两个时间样本期间(1992～1997年与1998～2004年)的就业和产出周期同步性均有所增加,说明商业周期的演进与我国经济体制改革基本同步;文章还分析了影响商业周期的不同解释变量,结果显示:控制变量的距离、规模与周期存在显著的相关性,而体现"东西边界"的外生变量则在绝大部分回归中则显著为负,说明在我国东西部之间可能存在一道明显的"区域分界线",阻碍了大区域间的经济联系;此外,樊刚指数对区域周期的解释具有两面性,经济结构差异越合理,商业周期越走向同步性,而财政政策差异和贸易密度差异是我国商业周期的波动因素.     

人民币实际汇率变动对我国进出口贸易影响:1997-2006

本文选取1997-2006年的月度数据,运用VAR方法,考虑了FDI存量和我国加工贸易特征的影响后,对贸易收支与人民币实际汇率变动关系进行了动态分析,并得出如下结论:人民币实际有效汇率的变动显著影响了我国贸易收支;短期内J曲线效应存在,时滞约为5个月;汇率变动对进出口贸易影响的同向性明显;我国贸易收支的收入效应大于价格效应等.     

期望效应与青年教师培养

期望是指对某事物或人未来前途有所希望和等待。期望效应具有暗示性、层次性、向心性、情感性。利用期望效应有益于加强青年教师的培养。     

供应链式虚拟经营对“牛鞭效应”的弱化分析

由于信息在供应链的各个企业中不对称,需求出现逐级的放大,产生"牛鞭效应"。在供应链中有选择的建立伙伴关系,采取供应链式虚拟经营有利于"牛鞭效应"的弱化。应认真筛选合作伙伴、加快信息的流通速度及采取VIM等方式来保证供应链式虚拟经营中信息渠道的通畅。     

Can China reduce the carbon emissions of its manufacturing exports by moving up the global value chain?

This study analyses whether embedding in the global value chain has an impact on the carbon emissions of China’s exports. We develop a carbon decomposition model and use panel data for 14 manufacturing industries in China from 1995 to 2009 to empirically analyse the impact of China’s exports on carbon emissions. Our results show that the GVC effect on China’s carbon emissions embodied in manufacturing exports outweighs the scale, composition and technique effects.     

The spillover effect of financial information in mergers and acquisitions

In this study we investigate whether and how a firm's investment activities are affected by the financial information of peer firms on merger and acquisition (M&A) efficiency. Using changes in M&A accounting performance to measure efficiency, we find a positive association between the post-M&A accounting performance of an acquiring firm and that of previous peer acquirers. We show that this spillover effect is derived from peer firms with improved rather than poorer post-M&A accounting performance. We also find that the spillover effect varies with the characteristics of both the acquiring and the peer firms. The effect is stronger when the peer firms are larger, are non-SOEs (vs. SOEs), have improved accounting performance after M&As and undertake M&As with unrelated (vs. related) entities, and when the acquiring firms are smaller, non-SOEs (vs. SOEs) and have poorer accounting performance before M&As.     

股票回购、现金股利替代性与研发投资——基于迎合渠道的比较分析

传统观点认为,股票回购与现金股利存在替代关系,同时在资金约束以及管理层短视情形下,二者对企业中长期研发投资支出产生负向冲击。而“边分红,边研发”却是目前我国上市公司的普遍现象。基于此背景,利用2014-2017年我国A股上市公司样本数据,在迎合渠道下分析股票回购与现金分红行为对研发投资的影响及差异。研究发现：两种分配行为并非具有完全替代性,虽然二者均会通过迎合渠道对研发投资产生正向影响,但迎合渠道又存在差异。其中,现金股利多通过股权融资渠道发挥作用,而股票回购多通过理性迎合渠道发挥作用。
