政府购买服务中高校参与及提升服务能力路径研究

高校是政府购买服务的承接方,但其对政府购买服务的响应还处在起步探索阶段。文章首先厘清政府购买服务中高校的角色定位,接着从外在驱动和内在诉求两个角度分析了高校参与政府购买服务的可行性,并在此基础上阐述高校参与政府采购服务的实施路径以及提升服务能力的路径。文章认为,高校应该把握好参与政府服务项目这个良好契机,以积极的态度参与政府购买服务,拓宽自身的发展路径,促成政府和高校实现双赢。     

污染源在线监测现状与优化建议

随着我国工业化进程的不断推进,在提升我国经济发展速度的同时,也带来了巨大的自然环境污染现象,特别是受到传统管理模式的影响,行业生产过程中缺乏环境保护意识,不仅造成了生产资源的大量浪费还在一定程度上影响了自然生态系统的可持续发展,对我国经济和自然生态均造成了极大损害.随着我国科技技术的不断发展和推进以及环保意识的增强,国家有关部门加大了环境保护管理的工作力度.本文主要分析污染源在线监测技术相关内容以及应用重要性,在分析存在的现状问题基础之上,开展污染源在线监测优化策略的探析,以期为我国环境保护工作提供一定参考价值.     

金融科技对传统银行行为的影响——基于互联网理财的视角

本文使用2011-2015年263家银行的年报数据和北京大学数字金融研究中心基于蚂蚁金服用户数据构建的地市级数字金融普惠指数,探究金融科技的发展对银行行为的影响。研究发现金融科技的发展实质上推动了一种变相的利率市场化,改变了银行的负债端结构,使得银行负债端越来越依赖于同业拆借等批发性资金。负债端结构的改变导致银行资产端风险承担偏好上升,但是借贷利率和净息差都有所下降。即银行选择了更高风险的资产来弥补负债端成本上升所造成的损失,但并没有将成本向下游企业转移。此外,本文还发现规模越大的银行受到金融科技的冲击越小。     

How is Benevolent Leadership Linked to Employee Creativity? The Mediating Role of Leader–Member Exchange and the Moderating Role of Power Distance Orientation

Previous research has shown that virtuous leader behavior in the form of benevolent leadership has considerable impact on employee creativity. However, little is known as to how and under what conditions these constructs are linked. In the current research, we proposed and tested a moderated mediation model positing leader–member exchange (LMX) as a mediator, and employee power-distance orientation as a moderator of this relationship. Two studies were conducted to test our hypothesized model. In Study 1, repeated measured data collected from 284 Chinese employees in an information technology company demonstrated that benevolent leadership had a lagged effect on LMX. In Study 2, analyses of multisource and lagged data from 391 Chinese employees in 42 research and development teams, and their direct supervisors indicated that benevolent leadership was positively related to supervisor-rated employee creativity via LMX. In addition, the relationship between benevolent leadership and LMX was stronger for employees high in power-distance orientation. Theoretical implications of benevolent leadership’s research and practical contributions concerning promoting creativity in organizations where benevolent leaders prevail are also discussed.

Board directors with foreign experience and stock price crash risk: Evidence from China

This study examines the impact of board directors with foreign experience (BDFEs) on stock price crash risk. We find that BDFEs help reduce crash risk. This association is robust to a series of robustness checks, including a firm fixed effects model, controlling for possibly omitted variables, and instrumental variable estimations. Moreover, we find that the negative association between BDFEs and crash risk is more pronounced for firms with more agency problems, weaker corporate governance, and less overall transparency. Our findings suggest that the characteristics of board directors matter in determining stock price crash risk.     

Volatility forecasting: long memory,regime switching and heteroscedasticity

In this article, we account for the first time for long memory, regime switching and the conditional time-varying volatility of volatility (heteroscedasticity) to model and forecast market volatility using the heterogeneous autoregressive model of realized volatility (HAR-RV) and its extensions. We present several interesting and notable findings. First, existing models exhibit significant nonlinearity and clustering, which provide empirical evidence on the benefit of introducing regime switching and heteroscedasticity. Second, out-of-sample results indicate that combining regime switching and heteroscedasticity can substantially improve predictive power from a statistical viewpoint. More specifically, our proposed models generally exhibit higher forecasting accuracy. Third, these results are widely consistent across a variety of robustness tests such as different forecasting windows, forecasting models, realized measures, and stock markets. Consequently, this study sheds new light on forecasting future volatility.
