“双高计划”呼唤高职院校补齐教师队伍建设短板

教师是兴教之本、立教之源,是实施"双高计划"建设最重要、最直接的力量。大力加强教师队伍建设是高职院校高质量发展的迫切要求。当前高职院校教师队伍存在总量不足、高层次人才短缺、双师素质不高、创新能力不强等问题,必须引育结合、创新机制、激发活力,补齐短板,提升整体实力和水平。     

改造我们的教学

进入"双高时代",我们距离新时代高等职业教育"舞龙头"的教学还有问题和"短板",应该改造教学方法和学习与研究制度。在剖析改造教学原因的基础上,厘清看待教学中存在问题的两种互相对立的态度,提出改造教学的革故鼎新路径,如强化"课堂教学为王"的意识,强化学习与专业研究,强化教学的职业素养,强化教师的课堂教学治理。     

Sustainable efficiency drivers in Eurasian airports: Fuzzy NDEA approach based on Shannon's entropy

This research explores the physical infrastructure and flight consolidation efficiency drivers of Eurasian airports regarding their infrastructure and movement productivity levels. A novel Fuzzy Double-Frontier Network DEA (FDFNDEA) model is proposed to investigate the relationship between desirable (freight and passenger turnovers) and undesirable (pollutant emission levels due to aircraft movements) outputs against the respective infrastructure usage, fuel consumed, and movements performed at each of the 23 Eurasian airports from 2000 to 2018. This balance between desirable and undesirable outputs emerges spatially and temporally due to the evolution of the airport system's productive resources at each one of the Eurasian countries over the period observed. Shannon's entropy is used as the cornerstone to quantify the input and output vagueness of this evolution in Triangular Fuzzy Numbers (TFN), thus allowing the accurate building of alternative optimistic and pessimistic double-frontier efficiency. Differently from previous research, Shannon's entropy is the key for measuring input and output vagueness levels in light of the maximal entropy principle. This principle states that the distribution that best represents the current state of knowledge is the one with largest entropy. Maximal entropy yields bias-free decision-making in the sense that the input/output distributional profiles for Eurasian airports contain the maximal possible heterogeneity, working as a robust or best/worst-case scenario against eventual unconsidered assumptions. Hence, optimistic and pessimistic Malmquist Productivity Indexes (MPI) for overall and each stage productivity results are subsequently regressed against contextual variables related to airport characteristics and regional socio-demographic and economic indicators of each Eurasian country using bootstrapped Cauchy regressions. The findings revealed the spatial heterogeneity of productivity factors and airport performance across Eurasia. Results also demonstrated the negative impact of income inequality and the positive impact of private participation on technological progression in the Eurasian airport industry.     

“双高”背景下北京高职院校招生困境和发展路径研究

“双高”建设背景下,培养服务区域发展的高素质技术技能人才成为高职教育的重要任务。这就要求高职院校首先要稳定办学规模,提升办学质量。而北京地区生源数量减少,非首都功能疏解等因素加大了招生工作困难。该研究从主客观因素及政策层面深入探讨了北京高职院校的招生困境,就当前职业教育面临的发展机遇,从对外宣传及学校内涵式建设的角度重点探索了“双高”背景下有效拓宽招生发展的路径。     

Value at risk and return in Chinese and the US stock markets: Double long memory and fractional cointegration

Given that the United States is an engine of global stock market while China is the largest emerging market with a cornucopia of anomalies in particular, it is vital to investigate the risk-return relationship in the two markets. This paper brings new insights not only into risk-return tradeoff, but also to the leverage effect, with the application of the fractionally co-integrated vector auto-regression (FCVAR) model capturing the fractional cointegrated relationship and long memory property. Results show that China stock markets own the property of double long memory but the US markets don’t. Most of all, in the US market, a positive risk-return tradeoff exists for the whole sample while after the crisis, even we find the negative relation, it’s not a volatility feedback effect but low risk and high returns. However, there is only a volatility feedback effect in China stock markets. Besides, there is a leverage effect in the US market, while Chinese market exhibits a reverse one, another anomaly, indicating significant difference in the two markets again.     

股权集中度视角下高管团队特征对现金股利政策的影响

现金股利政策是上市公司对盈利进行分配或留存用于再投资的决策问题,在公司经营中起着至关重要的作用。探究了高管团队特征(规模、年龄、性别、学历背景)对企业现金股利政策的影响,研究发现管理团队的规模越大、平均年龄越大,企业现金股利支付率越高,表明企业管理团队人数越多,年龄越大,越容易采用较高的股利支付率,而管理团队的平均学历越高,越倾向于选择较低的现金股利分配率。说明更高学历的管理层认为,较低的现金股利支付水平才是有利于企业发展的股利支付水平。男性管理层和女性管理者对企业支付现金股利的高低并没有明显的差异。进一步研究发现,企业的股权越集中,管理者的特征对现金股利政策的影响会被弱化。也就是说,股权集中度会显著削弱管理者特征对公司现金股利政策的影响,该实证结果也印证了上市公司中代理问题的普遍存在。研究结果可为企业管理团队的合理配置提出可以借鉴的依据以及实证结果的支持。     

现金股利、股权结构和组织特征:一个Logistic分析

本文以763家上海证券交易所A股上市公司2003年的横截面数据为观察值,运用logistic回归分析分别考察了股权结构和组织特征对现金股利发放概率的实证影响。本文发现,股权结构(第一大股东持股、前二大股东持股和前三大股东持股)对现金股利发放概率具有显著的正向影响。公司各项组织特征(成长性机会、每股收益、每股留存盈余、资产规模和财务杠杆)也对现金股利发放概率具有显著的影响。本文的结论支持自由现金流假说。     

股权结构与企业股利政策选择关系:理论与实证分析

本文从公司治理视角出发,以中国上市公司为样本,对股权结构与企业股利政策关系进行了理论与实证分析。结果表明,管理者持股比例、股权集中度(包括第一大股东持股比例)与现金股利支付率显著正相关;国有股比例与现金股利支付率正相关;法人股比例和流通A股比例对现金股利支付率的影响可能是负向的,且极不显著。     

The Global Preference for Dividends in Declining Markets

Investors globally prefer dividend‐paying stocks over nondividend‐paying stocks more in declining than in advancing markets, even accounting for firm‐level growth opportunities, size and risk effects. Dividend‐paying stocks outperform nondividend‐paying stocks, from 0.63% (China) to 3.79% (Canada) more per month in declining than in advancing markets. In declining markets, dividend‐paying firms outperform by more than any underperformance in advancing markets. The results are robust across dividend taxation regimes, legal environments, emerging and developed markets, periods prior to and after the 2008 global financial crisis, the exclusion of the dividend declaration month and in respect to segmented or integrated international capital markets.
