高速公路作为我国交通运输行业的重要枢纽,关乎广大人民的出行和交通运输行业的发展.作为交通运输行业建设中的关键,高速公路的施工质量显得尤为重要.路基路面病害是影响高速公路质量的主要因素,病害问题的出现不仅会影响高速公路的施工,还会产生一些安全隐患,对人民的日常出行造成威胁.针对施工过程中的一些常见病害进行把握,制定了针对性较强的应对措施,能够有效规避一些施工问题.本文结合我国高速公路施工的实际,针对一些常见病害进行探析.     

政府投资工程建设项目预算评审问题及对策

为了城市建设得到更好的发展,政府会对一些工程建设项目进行投资,在投资前需要对工程项目进行相关的预算评审,从而让其工程建设的市场环境保持相应秩序,并以此对工程标价掌控在理想范围内,提高财政资金的使用效益,避免投资预算出现超支的现象.     

瑞幸咖啡内部控制失效案例分析及措施研究

内部控制,作为如今企业最重要的内部机构组成部分,在公开财务报表、保证资产的安全、提升经营效率、优化经营效果、制定企业持续经营战略、保证企业经营管理方面的合法与合规等方面的重要性很高.本文运用文献分析、案例分析法等,对瑞幸咖啡在内控方面存在的问题进行分析.内控制度不完善,营运模式的不恰当,缺乏信息沟通造成的信息不对称,内部控制评价体系不健全,监督管理的失效,都是其进行虚假交易、虚增利润的推动力.     

基于Canopy-K-means算法的半挂汽车列车行驶数据分析

为实时监测车辆行驶状态,建立了基于Canopy-K-means算法的车辆行驶安全特征分类模型.采用Canopy-K-means聚类算法对车辆行驶数据进行挖掘分析,以欧氏距离大小作为数据集属性间的相似性分类指标,得到表征不同行驶安全特征的离线聚类质心;搭建T ruckSim与Simulink联合仿真平台,设置定半径变车速和方向盘斜阶跃输入仿真工况对车辆行驶状态进行在线识别;同时为验证该方法在实车上的应用效果,设置相同工况对离线聚类质心进行验证分析.仿真和实车结果表明:基于Canopy-K-means算法的数据挖掘方法可以对不同行驶状态数据进行分类,得到的表征不同行驶安全特征的聚类质心能在一定程度上对车辆行驶稳定性进行评价,可以作为车辆控制和预警的判定依据.     

R&D investment and future firm performance: The role of managerial overconfidence and government ownership

We investigate the relationship among managerial overconfidence (MO), government ownership, and research and development (R&D) investment using data from Vietnamese public companies for the period 2007–2016. We also investigate how R&D investment, given MO and government ownership, affect future firm performance. Our results indicate that MO and government ownership are positively related to R&D investment. Conceptually, this study investigates novel factors affecting of R&D investment and their role in improving firm performance. Overall, this study emphasizes the importance of R&D investment in the corporate world, improving firm performance and, ultimately, economic prosperity.     

Empathic cultural consumers: Pay what you want in the theater

Pay what you want (PWYW) is an increasingly popular sales strategy in which consumers voluntarily decide how much to pay for a product or service. PWYW has often been described as an exercise in the “empathy economy,” where consumers' payment choices might be seen as empowered expressions of their tastes and preferences, and sellers have a stronger incentive for empathizing with them. Beyond their economic interest, PWYW experiences also deserve significant attention in the social sciences given that they challenge several key assumptions of rational choice and neoclassical economic theory, as well as conventional consumer behavior and pricing theories. This paper analyzes three plays performed at the Beckett Theater in Barcelona using PWYW with very profitable outcomes. Our analysis shows that socio-psychological factors, such as payments attributed to others and satisfaction with the play, are the best predictors of customer payments.     

Energy prices and investment in energy efficiency: evidence from Chinese industry 1997–2004

The paper develops and implements a methodology for assessing the role of energy prices and new investment in reducing energy intensity in Chinese industry. Analysing a unique panel data set which reports firm-level energy consumption and price from 1997 to 2004, the paper finds: the energy prices, not only the current but also the past energy prices, are key factors that driving down firms' energy intensity for all three types of firms: state-owned enterprises (SOEs), domestic non-SOEs (NSOEs) and foreign-funded firms (FFEs); furthermore, SOEs exhibit a robust price-investment channel: responding to rising energy prices, SOEs tend to invest in new energy-efficient capital, through which SOEs reduce energy intensity; the same price-investment channels are less robust for non-SOEs or foreign-funded firms.     

基于内向开放式创新调节的组织柔性与领先企业持续成长能力研究

随着智能互联推动的第四次产业变革的到来与环境不确定性的加剧,近年来一些行业领先的大企业突然崩塌而另一些领先企业则实现了转型与持续成长。组织柔性、开放式创新是影响领先企业实现转型与持续成长的重要因素。引入内向开放式创新作为调节变量,通过问卷调查与数据分析,证实组织柔性是影响领先企业持续成长能力获取的重要因素,其中能力柔性影响最大,文化柔性和结构柔性次之,内向开放式创新则在两者关系中发挥正向调节效应。结合单案例研究发现,平台协同、利益共同体机制、市场导向是组织柔性、内向开放式创新促进领先企业持续成长的实践路径。     

基本医保城乡统筹新政实施状况研究——基于北京市居民政策知晓度与满意度的实证分析

本文基于“北京市城乡居民基本医保制度一体化理论与实证研究”重大项目调查数据， 通过对2017 年、2018 年居民政策知晓率、满意度差异性检验、因子分析与Ordinal 回归分析，对 比北京市城乡居民对“实施整合城乡居民基本医保”新政的反映（知晓率、满意度）及其影响因素， 发现：北京市城乡居民医保整合后满意度总体水平略微低于整合前，报销程序、定点医疗机构（可 及性、服务质量与态度）和报销比例是影响居民医保满意度的主要因子；其中，报销地点远近程度、 报销程序规定了解程度、定点医疗机构满意度、缴费额度规定了解程度、缴费额度满意度、门诊 报销比例满意度、报销比例规定了解程度、继续参加现参医保制度意愿是基本医保满意度外部因 素中的共性因素。本文研究揭示了城乡居民对医保新政的实际需求有共性（需要政府作为全局规 划时重点考虑的因素），但也呈现多样化和差异化（应该作为政府因地制宜制定政策时所需要权 衡的因素），对北京市乃至全国建立健全城乡统筹医保提供了实证资料、科学依据和政策参考。     

热钱流入的途径、规模及影响

2005年到2007年,中国股市冲向6000点高峰,而2008年以来却一泄千里。大量数据表明,中国境内流入的不明用途资本急剧增加。近年来大量热钱流入我国境内,对我国的金融市场和宏观经济带来了潜在的风险。防范国际短期资本大规模流入对我国造成的冲击,关键在于调控流入规模的同时有效地预测其迅速逆转的可能性。
