Foreign investment,corporate governance and performance in the Chinese listed A Share companies

We present a novel lens on the presence and impact of qualified foreign institutional investors (QFII) in top shareholdings of the non-financial domestically listed Chinese ‘A’ share firms. The initial results suggest that the presence of a QFII as a top shareholder in these companies is associated with their better performance, using both Tobin’s Q and ROA as the performance measures. Our models include variables representing corporate governance mechanisms, foreign legal person shares, a proxy for international affiliations and a number of time-variant firm characteristics. Economically, the coefficient of impact on the market measure is the more significant, while the effect of having a QFII in top shareholdings on both performance measures is empirically significant. Previously, studies have often ignored the potential for reverse causality beyond using lagged regressors. This is problematic. Therefore, we follow up with a 2SLS instrumental variables and system GMM model to further mitigate this potential and find the empirical relationship holds. Contrary to earlier work on QFIIs and governance post-implementation of the QFII scheme, the findings from our models suggest that the presence of a QFII top shareholder augments market performance holding equal existing corporate governance mechanisms and other controls.     

创业情境下管理强度与创业绩效关系探讨:团队合作的中介效应

创业活动以其良好的经济与社会效益越来越受到重视,创业过程的核心是创业要素之间的动态匹配。为诠释创业理念在创业者和创业成员之间的匹配,结合创业者特质和成熟企业管理制度演化两种理论视角,提出了创业情境下管理强度的概念,并构建了其与团队合作、新创企业绩效之间的理论模型。通过107份预测试问卷和171份正式问卷进行实证分析,结果发现:创业管理强度可以被划分为独特性、统一性、共识性3个维度;创业管理强度对创业企业绩效具有显著正向影响,这种正向影响机制可以从团队合作方面得到解释,即团队合作在创业管理强度和创业企业绩效之间发挥中介作用。

以政府职能转变推动收入分配改革

收入和财富分配的不平等一直是中国改革发展中的重要问题。针对中国经济的特点,可以从政府改革的角度来研究如何更好地进行收入分配改革。地方政府主导推动地方经济的做法对收入不平等的扩大起了重要作用,加快政府职能转换,是使收入分配改革真正落到实处的破局之处,也是实现收入分配合理化可行的第一步。要改变地方政府的经济职能,降低它直接参与基础设施的程度,改革地方土地财政,建立垂直管理机构,以分散它的一部分经济管理职能,为收入分配改革打开空间。     

The impact of crude oil inventory announcements on prices: Evidence from derivatives markets

This study examines the impact of weekly crude oil storage announcements on oil futures and options prices. We document evidence of a strong announcement day effect on both markets, and find prices to move in anticipation of the inventory surprise. Futures returns significantly decrease with positive surprises and increase with negative surprises. There is no evidence of an asymmetric impact on futures prices. Near‐the‐money options exhibit the greatest price sensitivity, and the magnitude of the price response of both futures and options declines with maturity. The results remain robust even after controlling for various macroeconomic and other storage‐related news variables.     

基于双kinect数据融合技术的工人作业疲劳智能化检测研究

本文针对制造型企业工人的作业疲劳检测问题,首先采用双kinect数据融合技术,提出了骨骼数据融合算法模型并应用于人体姿势识别,实现对工人作业疲劳姿势的智能化检测;然后将该算法与单kinect、Lin等算法比较,验证该算法的可靠性及识别精度;最后通过企业案例进行工人作业疲劳检测,结合人因工程学对工人动作进行分析并改善,对比验证结果表明,基于姿态角的双kinect人体姿势识别算法识别时间明显缩短,识别率显著增强,精准度较高,工人姿势识别数据具有较高可靠性.
