高速铁路站台雨棚运维管理系统可视化监测E-BIM应用研究

高速铁路站台雨棚结构监测是保证列车行车与旅客候车安全的重要环节。为提高站台雨棚的运维管理与监测效率,针对高速铁路站台雨棚运维管理系统可视化监测进行设计,建立高速铁路站台雨棚运维管理系统可视化监测实施流程。以广州局集团公司海南环岛高速铁路海口东站站台钢结构雨棚为依托,引入基于BIM技术的E-BIM结构进行可视化监测,开发适用于大跨度空站台雨棚运维管理系统的可视化监测模块,实现高速铁路站台雨棚的结构风险管控,确保高速铁路列车与旅客的安全。     

铁路企业建立职业经理人制度探索

为进一步深化铁路企业改革,加快完善市场化经营机制,应积极探索建立职业经理人制度。在阐述职业经理人制度政策依据的基础上,提出推进职业经理人制度建设的基本条件,即建立公司化的法人治理结构,并从优化产权结构、明确权责划分、推进董事会建设、发挥职业经理人作用等方面对建立健全铁路企业法人治理结构进行论述。从管理机制、激励约束机制、引进退出机制3个方面,探讨铁路企业建立职业经理人制度形成机制,提出铁路企业应按照分层分类改革原则,逐步推行职业经理人制度。     

技术创业型企业孵化资本投入的风险管控——来自多案例对比

待孵化的技术创业型企业同时具有概念性技术向差异化产品转化的高风险与产品异质性被认同后溢价评估的高收益特点，导致其投资者多处于隔岸观火却欲罢不能的的孵化投资矛盾中。对孵化资本实施有效的风险管控，成为吸引外部资本投入的关键。基于此，选择在可创概念选育与技术创业孵化领域探索出高成功率路径的概念证明中心、YCombinator和创新工场为研究案例，分析其在创业项目筛选、孵化资金运营等关键环节的风险管控方式，以期完善我国孵化资本管控理论、助力我国商业孵化器提高资金风险管控能力、促进外部资本投入。     

Board faultlines and the value of cash holdings: Evidence from Chinese listed companies

Faultlines can affect a board of director’s effectiveness in supervising senior managers, which in turn affects the value of a company’s cash holdings. Based on sample data from Chinese A-share listed companies from 2004 to 2016, we examine the relationship between board faultlines and the value of cash holdings. The empirical results indicate that board faultlines have a significant inhibitory effect on cash holding value. This inhibitory effect is stronger for board faultlines resulting from deep-level attributes. Furthermore, the inhibitory effect of board faultlines is stronger in state-owned enterprises (SOEs) than in non-SOEs. As an important governance mechanism, management shareholdings can reduce agency costs and mitigate the negative impact of board fissures on cash holdings. Overall, we enrich the literature on the economic consequences of board faultlines and their influence on cash holding value. We also offer companies practical suggestions for improving the supervisory mechanism of their board of directors.     

双元视角下调节聚焦对国防研发人员创新行为的影响机制

调节聚焦作为个体实现目标的动机调节系统，对个体创新行为具有重要作用，是组织行为学领域关注的热点。基于调节聚焦等相关理论，从二维视角深入考察个体调节聚焦对其双元创新的过程机理与边界机制。对527名国防科技研发人员进行问卷调研分析，结果发现：①促进聚焦和防御聚焦均正向预测双元创新及其平衡性与互补性，促进聚焦的预测作用更强；②探索式失败学习和利用式失败学习同时中介上述关系；③正向组织差错管理氛围正向调节促进聚焦与双元创新及其互补性的关系，负向组织差错管理氛围正向调节防御聚焦与双元创新及其互补性的关系。     

Drivers of management control systems in tourism start-ups firms

This study examines the use of Management Control Systems (MCS) in travel and tourism start-ups. The study empirically examines 176 European tourism start-ups; data are collected via an online survey of start-up CEOs, and supplemented by financial statements of early-stage tourism firms. The results show that travel and tourism start-ups use formal systems for management control. We observe a relationship between the usage of these systems with specific internal and external environment characteristics. Finally, the results show that the historical financial performance of travel and tourism start-up firms affects MCS usage.     

《土地管理法》成片开发征收标准的体系阐释

研究目的:阐明《土地管理法》成片开发征收标准的核心要旨及其体系构成。研究方法:规范分析法,文献分析法。研究结果:成片开发标准应当以促成公益目的实现为核心要义,并秉持系统思维,既要明确其面积范围、用地构成及类型、补偿方式等基本构成要素,还应建立征收权行使之事前、事中、事后全过程动态监控机制。研究结论:成片开发征收入法本身具有权宜性,待土地要素市场化配置机制更加健全,成片开发征收完成特定历史时期使命之后应退出公益征收范围。     

基于过程管理视角的开放式创新关系治理研究

开放式创新集价值创造与价值获取于一体，对于促进合作研发与创新成果转化具有积极作用。但是，创新主体间目标分歧、利益冲突等关系治理问题影响创新绩效与商业化成败，已成为制约开放式创新实践的主要障碍。基于“知识搜索→知识整合→商业化”的过程管理视角，考察了开放式创新关系治理问题的表现与产生机理，发现解决关系治理问题的关键是维护价值创造与价值获取间动态均衡，提出了以信任及关系规范为主体的关系治理机制理论框架，并从合作关系的内在规则与外在行为两个方面论证了关系治理机制的作用效果。     

绿色人力资源管理实践感知、资质过高感与员工绿色行为

企业绿色人力资源管理实践旨在通过激发员工绿色环保行为，实现企业绿色可持续发展。员工资质过高感虽然是影响员工行为的重要因素之一，但绿色人力资源管理研究对其关注甚少。为此，以员工为调查对象，基于个体层面，从资质过高感研究绿色人力资源管理实践感知与员工绿色行为的关系。结果发现：绿色人力资源管理实践感知与员工绿色行为显著正相关，资质过高感发挥U型调节作用。结论可为组织绿色人力资源管理实践提供有益参考。     

Contagion between real estate and financial markets: A Bayesian quantile-on-quantile approach

We study contagion between Real Estate Investment Trusts (REITs) and the equity market in the U.S. over four sub-samples covering January, 2003 to December, 2017, by using Bayesian nonparametric quantile-on-quantile (QQ) regressions with heteroskedasticity. We find that the spillovers from the REITs on to the equity market has varied over time and quantiles defining the states of these two markets across the four sub-samples, thus providing evidence of shift-contagion. Further, contagion from REITs upon the stock market went up during the global financial crisis particularly, and also over the period corresponding to the European sovereign debt crisis, relative to the pre-crisis period. Our main findings are robust to alternative model specifications of the benchmark Bayesian QQ model, especially when we control for omitted variable bias using the heteroskedastic error structure. Our results have important implications for various agents in the economy namely, academics, investors and policymakers.
